Subject: [PATCH 080/944] added digits10() implementation for NumTraits for
 mpfr_float, and consequently the bertini::complex

a compile error was happening in GCC5.4, eigen 3.3.4 because couldn't convert from ceil(mpfr_float) to int.  this is due to a bug in Boost.Multiprecision in versions 1.58.  It was fixed at some point.

 will compile with not clang.

clang compiles so much better than gcc 4.9, and 5.4.  let the record show that i still love gcc.

+Welcome to PyBertini
+====================================
+
+We're glad you are here with us.  Bertini is software for numerically solving systems of polynomials.  PyBertini is the Python provided for running Bertini interactively.
+
+The main algorithm in Bertini is homotopy continuation.  A homotopy is formed, and the solutions to the start system are continued into the solutions for the target system.

+Tutorial
+********
+
+PyBertini works by setting up systems, setting up algorithms to use those systems, and doing something with the output.
+
+Forming a system
+================
+
+
+Let's make a couple of variables::
+	
+	x = pybertini.function_tree.symbol.Variable("x") #yes, you can make a variable not match its name...
+	y = pybertini.function_tree.symbol.Variable("y")
+
+Now, make a few symbolic expressions out of them::
+	
+	f = x**2 + y**2 -1
+	g = x+y
+
+There's no need to "set them equal to 0" -- expressions used as functions in a system in Bertini are taken to be equal to zero.  If you have an equality that's not zero, move one side to the other.
+
+Let's make an empty system, then build into it::
+	
+	sys = pybertini.System()
+	sys.add_function(f)
+	sys.add_function(g)
+
+``sys`` doesn't know its variables yet, so let's group them into an affine variable group [#]_, and stuff it into ``sys``::
+	
+	grp = pybertini.VariableGroup()
+	grp.append(x)
+	grp.append(y)
+	sys.add_variable_group(grp)
+
+We add the functions to the system::
+
+	sys.add_function(f)
+	sys.add_function(g)
+
+Let's check that the degrees of our functions are correct::
+
+	d = sys.degrees()
+	assert(d[0]==2)
+	assert(d[1]==1)
+
+What happens if we add a non-polynomial function to our system?::
+
+	sys.add_function(x**-1)
+	sys.add_function( pybertini.function_tree.sin(x) )
+	d = sys.degrees()
+	assert(d[2]==-1) # unsurprising, but actually a coincidence
+	assert(d[3]==-1) # also -1.  anything non-polynomial is a negative number.  sin has no degree
+
+
+Forming a homotopy
+==================
+
+A homotopy in Numerical Algebraic Geometry glues together a start system and a target system.  Above, we formed a target system, ``sys``.  Now, let's make a start system ``td``, and couple it to ``sys``.
+
+The most basic, easiest to form and solve, start system is the Total Degree (TD) start system.  It is implemented as a first-class object in Bertini and PyBertini.  It takes in a polynomial system as its argument, and self-forms.::
+	
+	del sys #we mal-formed our system by adding too many functions, and non-polynomial functions to it.
+	# so, we start over
+	sys = pybertini.System()
+	sys.add_variable_group(grp)
+	sys.add_function(f)
+	sys.add_function(g)
+
+	td = pybertini.TotalDegree(sys)
+
+Wonderful, now we have an easy-to-solve system, the structure of which mirrors that of our target system.  Every start system comes with a method for generating its start points, by integer index.::
+	
+	# generates the 1th (0-based offsets in python) start point
+	# at double precision
+	td.start_pointd(1) 
+
+	# generate the 1th point at current multiple precision
+	sp = td.start_pointmp(1)
+	assert(pybertini.default_precision() == sp[1].precision())
+
+Finally, we couple ``sys`` and ``td``::
+	
+	t = pybertini.function_tree.symbol.Variable("t")
+	homotopy = (1-t)*sys + t*td
+	homotopy.add_path_variable(t)
+
+Now, we have the minimum theoretical ingredients for solving a polynomial system using Numerical Algebraic Geometry: a homotopy, a target system, and a start system.
+
+Tracking a single path
+======================
+
+There are three basic trackers available in PyBertini:
+
+#. Fixed double precision: ``pybertini.tracking.DoublePrecisionTracker``
+#. Fixed multiple precision: ``pybertini.tracking.MultiplePrecisionTracker``
+#. Adaptive precision: ``pybertini.tracking.AMPTracker``
+
+Each brings its own advantages and disadvantages.  And, each has its ambient numeric type.  
+
+Let's use the adaptive one, since adaptivity is generally a good trait to have.  ``AMPTracker`` uses variable-precision vectors and matrices in its ambient work -- that is, you feed it multiprecisions, and get back multiprecisions.  Internally, it will use double precision when it can, and higher when it has to.
+
+We associate a system with a tracker when we make it.  You cannot make a tracker without telling the tracker which system it will be tracking...::
+	
+	tr = pybertini.tracking.AMPTracker(homotopy)
+	tr.set_tolerance(1e-5) # track the path to 5 digits or so
+
+	# adjust some stepping settings
+	stepping = pybertini.tracking.config.SteppingConfig()
+	stepping.max_step_size = pybertini.mpfr_rational(1,13)
+
+	#then, set the config into the tracker.
+
+
+Once we feel comfortable with the configs (of which there are many, see the book or elsewhere in this site, perhaps), we can track a path.::
+	
+	result = pybertini.VectorXmp()
+	tr.track_path(result, pybertini.mpfr_complex(0), pybertini.mpfr_complex(1), td.start_pointmp(0))
+
+
+Using and endgame to compute singular endpoints
+===============================================
+
+
+A complete zerodim solve

-Using and endgame to compute singular endpoints
+Using an endgame to compute singular endpoints
 ===============================================
 
+There are two implemented endgames in Bertini:
+
+#. Power series -- uses `Hermite interpolation <https://en.wikipedia.org/wiki/Hermite_interpolation>`_ across a sequence of geometrically-spaced points (in time) to extrapolate to a target time.
+#. Cauchy -- uses `Cauchy's integral formula <https://en.wikipedia.org/wiki/Cauchy's_integral_formula>`_
+
+Each is provided in the three precision modes, double, fixed multiple, and adaptive.  Since we are using the adaptive tracker in this tutorial, we will of course use the adaptive endgame.  I really like the Cauchy endgame, so we're in the land of the ``pybertini.endgame.AMPCauchyEG``. 
+
+To make an endgame, we need to feed it the tracker that is used to run.  There are also config structs to play with, that control the way things are computed.
+
+::
+
+	eg = pybertini.endgame.AMPCauchyEG(tr)
+
+Since the endgame hasn't been run yet things are empty and default::
+
+	assert(eg.cycle_number()==0)
+	assert(eg.final_approximation()==pybertini.VectorXmp())
+
+The endgames are used by invoking ``run``, feeding it the point we are tracking on, the time we are at, and the time we want to track to.

this is to make exposing catergories of interaction much easier -- which it is.  found that cannot get gmp_int to interact with bertini::complex!  so this code will not compile.  next is to add that interaction.  then, recompile the world.

Subject: [PATCH 137/944] working on getting float/float to be exposed.

for some insane reason, it's not right now.  i don't get it.  float+float, float-float, and float*float are all good.  but float/float is missing, and it's really frustrating.

+Tutorial - Evaluation of cyclic-:math:`n` polynomials
+*******************************************************
+
+Bertini is software for algebraic geometry.  This means we work with systems of polynomials, a critical component of which is system and function evaluation.
+
+Bertini2 allows us to set up many kinds of functions, and thus systems, by exploting operator overloading.
+
+Make some symbols
+==================
+
+Let's start by making some variables, programmatically [1]_.  
+
+::
+
+	import pybertini
+	import numpy
+
+	num_vars = 10
+	x = [None] * num_vars
+	for ii in range(num_vars):
+	    x[ii] = pybertini.Variable('x' + str(ii))
+
+Huzzah, we have `num_vars` variables!  This was hard to do in Bertini 1's classic style input files.  Now we can do it directly! 🎯
+
+Write a function to produce the cyclic :math:`n` polynomials :cite:`cyclic_n`.
+
+::
+
+	def cyclic(vars):
+	    n = len(vars)
+	    f = [None] * len(vars)
+	    y = []
+	    for ii in range(2):
+	        for x in vars:
+	            y.append(x)
+	        
+	    for ii in range(n):
+	        f[ii] = numpy.sum( [numpy.prod(y[jj:jj+ii+1]) for jj in range(n)] ) 
+	    
+	    # the last one is minus one
+	    f[-1] = f[-1]-1
+	    return f
+
+Now we will make a System, and put the cyclic polynomials into it.
+
+::
+
+	sys = pybertini.System()
+
+	for f in cyclic(x):
+	    sys.add_function(f)
+	    
+	print(sys) # long screen output, i know
+
+
+.. [1] This is one of the reasons we wrote Bertini2's symbolic C++ core and exposed it to Python.

+Tutorial - Evaluation of cyclic-:math:`n` polynomials
+*******************************************************
+
+Bertini is software for algebraic geometry.  This means we work with systems of polynomials, a critical component of which is system and function evaluation.
+
+Bertini2 allows us to set up many kinds of functions, and thus systems, by exploting operator overloading.
+
+Make some symbols
+==================
+
+Let's start by making some variables, programmatically [1]_.  
+
+::
+
+	import pybertini
+	import numpy
+
+	num_vars = 10
+	x = [None] * num_vars
+	for ii in range(num_vars):
+	    x[ii] = pybertini.Variable('x' + str(ii))
+
+Huzzah, we have `num_vars` variables!  This was hard to do in Bertini 1's classic style input files.  Now we can do it directly! 🎯
+
+Write a function to produce the cyclic :math:`n` polynomials :cite:`cyclic_n`.
+
+::
+
+	def cyclic(vars):
+	    n = len(vars)
+	    f = [None] * len(vars)
+	    y = []
+	    for ii in range(2):
+	        for x in vars:
+	            y.append(x)
+	        
+	    for ii in range(n):
+	        f[ii] = numpy.sum( [numpy.prod(y[jj:jj+ii+1]) for jj in range(n)] ) 
+	    
+	    # the last one is minus one
+	    f[-1] = f[-1]-1
+	    return f
+
+Now we will make a System, and put the cyclic polynomials into it.
+
+::
+
+	sys = pybertini.System()
+
+	for f in cyclic(x):
+	    sys.add_function(f)
+	    
+	print(sys) # long screen output, i know
+
+
+.. [1] This is one of the reasons we wrote Bertini2's symbolic C++ core and exposed it to Python.

+Tutorial - Tracking to nonsingular endpoints
+**********************************************
+
+PyBertini works by setting up systems, setting up algorithms to use those systems, and doing something with the output.
+
+Forming a system
+=================
+
+
+Let's make a couple of variables::
+
+	x = pybertini.function_tree.symbol.Variable("x") #yes, you can make a variable not match its name...
+	y = pybertini.function_tree.symbol.Variable("y")
+
+Now, make a few symbolic expressions out of them::
+
+	f = x**2 + y**2 -1
+	g = x+y
+
+There's no need to "set them equal to 0" -- expressions used as functions in a system in Bertini are taken to be equal to zero.  If you have an equality that's not zero, move one side to the other.
+
+Let's make an empty system, then build into it::
+
+	sys = pybertini.System()
+	sys.add_function(f)
+	sys.add_function(g)
+
+``sys`` doesn't know its variables yet, so let's group them into an affine variable group [#]_, and stuff it into ``sys``::
+
+	grp = pybertini.VariableGroup()
+	grp.append(x)
+	grp.append(y)
+	sys.add_variable_group(grp)
+
+Let's check that the degrees of our functions are correct::
+
+	d = sys.degrees()
+	assert(d[0]==2)
+	assert(d[1]==1)
+
+What happens if we add a non-polynomial function to our system?
+
+::
+
+	sys.add_function(x**-1)
+	sys.add_function( pybertini.function_tree.sin(x) )
+	d = sys.degrees()
+	assert(d[2]==-1) # unsurprising, but actually a coincidence
+	assert(d[3]==-1) # also -1.  anything non-polynomial is a negative number.  sin has no degree
+
+
+Forming a homotopy
+==================
+
+A homotopy in Numerical Algebraic Geometry glues together a start system and a target system.  Above, we formed a target system, ``sys``.  Now, let's make a start system ``td``, and couple it to ``sys``.
+
+The most basic, easiest to form and solve, start system is the Total Degree (TD) start system.  It is implemented as a first-class object in Bertini and PyBertini.  It takes in a polynomial system as its argument, and self-forms.::
+
+	del sys #we mal-formed our system above by adding too many functions, and non-polynomial functions to it.
+	# so, we start over
+	sys = pybertini.System()
+	sys.add_variable_group(grp)
+	sys.add_function(f)
+	sys.add_function(g)
+
+	td = pybertini.TotalDegree(sys)
+
+Wonderful, now we have an easy-to-solve system, the structure of which mirrors that of our target system.  Every start system comes with a method for generating its start points, by integer index.::
+
+	# generates the 1th (0-based offsets in python) start point
+	# at double precision
+	td.start_point_d(1)
+
+	# generate the 1th point at current multiple precision
+	sp = td.start_point_mp(1)
+	assert(pybertini.default_precision() == sp[1].precision())
+
+Finally, we couple ``sys`` and ``td``::
+
+	t = pybertini.function_tree.symbol.Variable("t")
+	homotopy = (1-t)*sys + t*td
+	homotopy.add_path_variable(t)
+
+Now, we have the minimum theoretical ingredients for solving a polynomial system using Numerical Algebraic Geometry: a homotopy, a target system, and a start system.
+
+Tracking a single path
+======================
+
+There are three basic trackers available in PyBertini:
+
+#. Fixed double precision: ``pybertini.tracking.DoublePrecisionTracker``
+#. Fixed multiple precision: ``pybertini.tracking.MultiplePrecisionTracker``
+#. Adaptive precision: ``pybertini.tracking.AMPTracker``
+
+Each brings its own advantages and disadvantages.  And, each has its ambient numeric type.
+
+Let's use the adaptive one, since adaptivity is generally a good trait to have.  ``AMPTracker`` uses variable-precision vectors and matrices in its ambient work -- that is, you feed it multiprecisions, and get back multiprecisions.  Internally, it will use double precision when it can, and higher when it has to.
+
+We associate a system with a tracker when we make it.  You cannot make a tracker without telling the tracker which system it will be tracking...
+
+::
+
+	tr = pybertini.tracking.AMPTracker(homotopy)
+	tr.set_tolerance(1e-5) # track the path to 5 digits or so
+
+	# adjust some stepping settings
+	stepping = pybertini.tracking.config.SteppingConfig()
+	stepping.max_step_size = pybertini.multiprec.rational(1,13)
+
+	#then, set the config into the tracker.
+
+
+Once we feel comfortable with the configs (of which there are many, see the book or elsewhere in this site, perhaps), we can track a path.
+
+::
+
+	result = pybertini.VectorXmp()
+	tr.track_path(result, pybertini.multiprec.complex(1), pybertini.multiprec.complex(0), td.start_point_mp(0))
+
+Let's generate a log of what was computed along the way, first making an observer, and then attaching it to the tracker.
+
+::
+
+	#make observer
+
+	#attach
+
+Re-running it, you should find the logfile ``bertini#.log``.
+
+Using an endgame to compute singular endpoints
+===============================================
+
+There are two implemented endgames in Bertini:
+
+#. Power series -- uses `Hermite interpolation <https://en.wikipedia.org/wiki/Hermite_interpolation>`_ across a sequence of geometrically-spaced points (in time) to extrapolate to a target time.
+#. Cauchy -- uses `Cauchy's integral formula <https://en.wikipedia.org/wiki/Cauchy's_integral_formula>`_
+
+Each is provided in the three precision modes, double, fixed multiple, and adaptive.  Since we are using the adaptive tracker in this tutorial, we will of course use the adaptive endgame.  I really like the Cauchy endgame, so we're in the land of the ``pybertini.endgame.AMPCauchyEG``.
+
+To make an endgame, we need to feed it the tracker that is used to run.  There are also config structs to play with, that control the way things are computed.
+
+::
+
+	eg = pybertini.endgame.AMPCauchyEG(tr)
+
+Since the endgame hasn't been run yet things are empty and default::
+
+	assert(eg.cycle_number()==0)
+	assert(eg.final_approximation()==pybertini.VectorXmp())
+
+The endgames are used by invoking ``run``, feeding it the point we are tracking on, the time we are at, and the time we want to track to.
+
+
+
+A complete tracking of paths
+=============================
+
+::
+	
+	import pybertini
+
+	x = pybertini.function_tree.symbol.Variable("x") #yes, you can make a variable not match its name...
+	y = pybertini.function_tree.symbol.Variable("y")
+	f = x**2 + y**2 -1
+	g = x+y
+
+	sys = pybertini.System()
+	sys.add_function(f)
+	sys.add_function(g)
+
+	grp = pybertini.VariableGroup()
+	grp.append(x)
+	grp.append(y)
+	sys.add_variable_group(grp)
+
+	td = pybertini.start_system.TotalDegree(sys)
+
+	t = pybertini.function_tree.symbol.Variable("t")
+	homotopy = (1-t)*sys + t*td
+	homotopy.add_path_variable(t)
+
+	tr = pybertini.tracking.AMPTracker(homotopy)
+
+	g = pybertini.tracking.observers.amp.GoryDetailLogger()
+
+	tr.add_observer(g)
+	tr.tracking_tolerance(1e-5) # track the path to 5 digits or so
+	tr.infinite_truncation_tolerance(1e5)
+	# tr.predictor(pybertini.tracking.Predictor.RK4)
+	stepping = pybertini.tracking.config.SteppingConfig()
+	# stepping.max_step_size = pybertini.multiprec.rational(1,13)
+
+	results = []
+
+	for ii in range(td.num_start_points()):
+		results.append(pybertini.multiprec.Vector())
+		tr.track_path(result=results[-1], start_time=pybertini.multiprec.complex(1), end_time=pybertini.multiprec.complex(0), start_point=td.start_point_mp(ii))
+
+	tr.remove_observer(g)

-Evaluation of the cyclic-:math:`n` polynomials
-*******************************************************
-
-Bertini is software for algebraic geometry.  This means we work with systems of polynomials, a critical component of which is system and function evaluation.
-
-Bertini2 allows us to set up many kinds of functions, and thus systems, by exploting operator overloading.
-
-Make some symbols
-==================
-
-Let's start by making some variables, programmatically [1]_.  
-
-::
-
-	import pybertini
-	import numpy
-
-	num_vars = 10
-	x = [None] * num_vars
-	for ii in range(num_vars):
-	    x[ii] = pybertini.Variable('x' + str(ii))
-
-Huzzah, we have `num_vars` variables!  This was hard to do in Bertini 1's classic style input files.  Now we can do it directly! 🎯
-
-Write a function to produce the cyclic :math:`n` polynomials :cite:`cyclic_n`.
-
-::
-
-	def cyclic(vars):
-	    n = len(vars)
-	    f = [None] * len(vars)
-	    y = []
-	    for ii in range(2):
-	        for x in vars:
-	            y.append(x)
-	        
-	    for ii in range(n):
-	        f[ii] = numpy.sum( [numpy.prod(y[jj:jj+ii+1]) for jj in range(n)] ) 
-	    
-	    # the last one is minus one
-	    f[-1] = f[-1]-1
-	    return f
-
-Now we will make a System, and put the cyclic polynomials into it.
-
-::
-
-	sys = pybertini.System()
-
-	for f in cyclic(x):
-	    sys.add_function(f)
-	    
-	print(sys) # long screen output, i know
-
-
-.. [1] This is one of the reasons we wrote Bertini2's symbolic C++ core and exposed it to Python.

-Tracking to nonsingular endpoints
-**********************************************
-
-PyBertini works by setting up systems, setting up algorithms to use those systems, and doing something with the output.
-
-Forming a system
-=================
-
-
-Let's make a couple of variables::
-
-	x = pybertini.function_tree.symbol.Variable("x") #yes, you can make a variable not match its name...
-	y = pybertini.function_tree.symbol.Variable("y")
-
-Now, make a few symbolic expressions out of them::
-
-	f = x**2 + y**2 -1
-	g = x+y
-
-There's no need to "set them equal to 0" -- expressions used as functions in a system in Bertini are taken to be equal to zero.  If you have an equality that's not zero, move one side to the other.
-
-Let's make an empty system, then build into it::
-
-	sys = pybertini.System()
-	sys.add_function(f)
-	sys.add_function(g)
-
-``sys`` doesn't know its variables yet, so let's group them into an affine variable group [#]_, and stuff it into ``sys``::
-
-	grp = pybertini.VariableGroup()
-	grp.append(x)
-	grp.append(y)
-	sys.add_variable_group(grp)
-
-Let's check that the degrees of our functions are correct::
-
-	d = sys.degrees()
-	assert(d[0]==2)
-	assert(d[1]==1)
-
-What happens if we add a non-polynomial function to our system?
-
-::
-
-	sys.add_function(x**-1)
-	sys.add_function( pybertini.function_tree.sin(x) )
-	d = sys.degrees()
-	assert(d[2]==-1) # unsurprising, but actually a coincidence
-	assert(d[3]==-1) # also -1.  anything non-polynomial is a negative number.  sin has no degree
-
-
-Forming a homotopy
-==================
-
-A homotopy in Numerical Algebraic Geometry glues together a start system and a target system.  Above, we formed a target system, ``sys``.  Now, let's make a start system ``td``, and couple it to ``sys``.
-
-The most basic, easiest to form and solve, start system is the Total Degree (TD) start system.  It is implemented as a first-class object in Bertini and PyBertini.  It takes in a polynomial system as its argument, and self-forms.::
-
-	del sys #we mal-formed our system above by adding too many functions, and non-polynomial functions to it.
-	# so, we start over
-	sys = pybertini.System()
-	sys.add_variable_group(grp)
-	sys.add_function(f)
-	sys.add_function(g)
-
-	td = pybertini.TotalDegree(sys)
-
-Wonderful, now we have an easy-to-solve system, the structure of which mirrors that of our target system.  Every start system comes with a method for generating its start points, by integer index.::
-
-	# generates the 1th (0-based offsets in python) start point
-	# at double precision
-	td.start_point_d(1)
-
-	# generate the 1th point at current multiple precision
-	sp = td.start_point_mp(1)
-	assert(pybertini.default_precision() == sp[1].precision())
-
-Finally, we couple ``sys`` and ``td``::
-
-	t = pybertini.function_tree.symbol.Variable("t")
-	homotopy = (1-t)*sys + t*td
-	homotopy.add_path_variable(t)
-
-Now, we have the minimum theoretical ingredients for solving a polynomial system using Numerical Algebraic Geometry: a homotopy, a target system, and a start system.
-
-Tracking a single path
-======================
-
-There are three basic trackers available in PyBertini:
-
-#. Fixed double precision: ``pybertini.tracking.DoublePrecisionTracker``
-#. Fixed multiple precision: ``pybertini.tracking.MultiplePrecisionTracker``
-#. Adaptive precision: ``pybertini.tracking.AMPTracker``
-
-Each brings its own advantages and disadvantages.  And, each has its ambient numeric type.
-
-Let's use the adaptive one, since adaptivity is generally a good trait to have.  ``AMPTracker`` uses variable-precision vectors and matrices in its ambient work -- that is, you feed it multiprecisions, and get back multiprecisions.  Internally, it will use double precision when it can, and higher when it has to.
-
-We associate a system with a tracker when we make it.  You cannot make a tracker without telling the tracker which system it will be tracking...
-
-::
-
-	tr = pybertini.tracking.AMPTracker(homotopy)
-	tr.set_tolerance(1e-5) # track the path to 5 digits or so
-
-	# adjust some stepping settings
-	stepping = pybertini.tracking.config.SteppingConfig()
-	stepping.max_step_size = pybertini.multiprec.rational(1,13)
-
-	#then, set the config into the tracker.
-
-
-Once we feel comfortable with the configs (of which there are many, see the book or elsewhere in this site, perhaps), we can track a path.
-
-::
-
-	result = pybertini.VectorXmp()
-	tr.track_path(result, pybertini.multiprec.complex(1), pybertini.multiprec.complex(0), td.start_point_mp(0))
-
-Let's generate a log of what was computed along the way, first making an observer, and then attaching it to the tracker.
-
-::
-
-	#make observer
-
-	#attach
-
-Re-running it, you should find the logfile ``bertini#.log``.
-
-Using an endgame to compute singular endpoints
-===============================================
-
-There are two implemented endgames in Bertini:
-
-#. Power series -- uses `Hermite interpolation <https://en.wikipedia.org/wiki/Hermite_interpolation>`_ across a sequence of geometrically-spaced points (in time) to extrapolate to a target time.
-#. Cauchy -- uses `Cauchy's integral formula <https://en.wikipedia.org/wiki/Cauchy's_integral_formula>`_
-
-Each is provided in the three precision modes, double, fixed multiple, and adaptive.  Since we are using the adaptive tracker in this tutorial, we will of course use the adaptive endgame.  I really like the Cauchy endgame, so we're in the land of the ``pybertini.endgame.AMPCauchyEG``.
-
-To make an endgame, we need to feed it the tracker that is used to run.  There are also config structs to play with, that control the way things are computed.
-
-::
-
-	eg = pybertini.endgame.AMPCauchyEG(tr)
-
-Since the endgame hasn't been run yet things are empty and default::
-
-	assert(eg.cycle_number()==0)
-	assert(eg.final_approximation()==pybertini.VectorXmp())
-
-The endgames are used by invoking ``run``, feeding it the point we are tracking on, the time we are at, and the time we want to track to.
-
-
-
-A complete tracking of paths
-=============================
-
-::
-	
-	import pybertini
-
-	x = pybertini.function_tree.symbol.Variable("x") #yes, you can make a variable not match its name...
-	y = pybertini.function_tree.symbol.Variable("y")
-	f = x**2 + y**2 -1
-	g = x+y
-
-	sys = pybertini.System()
-	sys.add_function(f)
-	sys.add_function(g)
-
-	grp = pybertini.VariableGroup()
-	grp.append(x)
-	grp.append(y)
-	sys.add_variable_group(grp)
-
-	td = pybertini.start_system.TotalDegree(sys)
-
-	t = pybertini.function_tree.symbol.Variable("t")
-	homotopy = (1-t)*sys + t*td
-	homotopy.add_path_variable(t)
-
-	tr = pybertini.tracking.AMPTracker(homotopy)
-
-	g = pybertini.tracking.observers.amp.GoryDetailLogger()
-
-	tr.add_observer(g)
-	tr.tracking_tolerance(1e-5) # track the path to 5 digits or so
-	tr.infinite_truncation_tolerance(1e5)
-	# tr.predictor(pybertini.tracking.Predictor.RK4)
-	stepping = pybertini.tracking.config.SteppingConfig()
-	# stepping.max_step_size = pybertini.multiprec.rational(1,13)
-
-	results = []
-
-	for ii in range(td.num_start_points()):
-		results.append(pybertini.multiprec.Vector())
-		tr.track_path(result=results[-1], start_time=pybertini.multiprec.complex(1), end_time=pybertini.multiprec.complex(0), start_point=td.start_point_mp(ii))
-
-	tr.remove_observer(g)
-

+Flavors
+=========
+
+There are two basic flavors of endgame implemented:
+
+1. Power Series, commonly written PS or PSEG
+2. Cauchy
+
+Both estimate the cycle number and use it to compute a root at a time which is never tracked to.  PSEG uses Hermite interpolation and extrapolation, and Cauchy uses loops around the target time coupled with the `Cauchy integral formula <https://en.wikipedia.org/wiki/Cauchy%27s_integral_formula>`_.  Both continue until two successive approximations of the root match to a given tolerance (:py:attr:`pybertini.endgame.config.Endgame.final_tolerance`).
+
+The implementations of the endgames go with a particular tracker, hence there are six provided endgame types.  Choose the one that goes with your selected tracker type.  Adaptive Multiple Precision is a good choice.

+
+Trackers in Bertini2 are stateful objects, that refer to a system they are tracking, hold their specific settings, and have a notion of current time and space value.
+
+Here are some particular classes and functions to pay attention to:
+
+* :class:`pybertini.tracking.AMPTracker`
+* :class:`pybertini.tracking.DoublePrecisionTracker`
+* :class:`pybertini.tracking.MultiplePrecisionTracker`
+
+Here are the implemented ODE predictors you can choose from:
+
+* :class:`pybertini.tracking.Predictor`
+
+Calls to :meth:`track_path` return a :class:`pybertini.tracking.SuccessCode`.

+Building PyBertini
+*******************
 
+This part is unsatisfactory to me.  I really wish the package would just detect dependencies, and build itself.  However, since there is a C++ library behind it, this is not yet implemented.  For now, you have to configure, compile, and install yourself.
 
-When configuring to build PyBertini, against Bertini2 installed to your computer, pay attention to the following.

+The definitive resource for Bertini 1 is the book :cite:`bertinibook`.  While the way we interact with Bertini changes from version 1 to version 2, particularly when using PyBertini, the algorithms remain fundamentally the same.  So do most of the ways to change settings for the path trackers, etc.  We believe that embracing the flexibility of Python3 with PyBertini allows for much greater flexibility.  It also will relieve the user from the burden of input and output file writing and parsing.  Instead, computed results are returned directly to the user.  
 
+Consider checking out the :ref:`tutorials`.

+### Important note on cloning
+
+The recommended method for getting the code for Bertini 2 is to clone from command line using git:
+
+`git clone https://github.com/bertiniteam/b2 --recursive`
+
+This ensures that any other repo's we depend on get cloned into their correct locations.  We have at least one for the Python bindings -- [MiniEigen](https://github.com/eudoxos/minieigen).

 # Overview
 
 The solution of arbitrary polynomial systems is an area of active research, and has many applications in math, science and engineering.  This program, Bertini 2, builds on the success of the first Bertini program, and seeks to eventually replace it entirely, as a powerful numerical engine.
 
-The theoretical basis for the solution of polynomials with Bertini is "homotopy continuation", the act of "continuing" from one system into another through a "homotopy", as depicted in the below diagram.
+The theoretical basis for the solution of polynomials with Bertini is a theorem which gives a statement on the number of solutions such a system may have, together with the numerical computational tool of "homotopy continuation", the act of "continuing" from one system into another through a "homotopy", as depicted in the below diagram.

+Using an endgame to compute singular endpoints
+***************************************************
+
+
+
+Background
+==============
+
+
+
+
+Application
+=============
+
+There are two implemented endgames in Bertini:
+
+#. Power series -- uses `Hermite interpolation <https://en.wikipedia.org/wiki/Hermite_interpolation>`_ across a sequence of geometrically-spaced points (in time) to extrapolate to a target time.
+#. Cauchy -- uses `Cauchy's integral formula <https://en.wikipedia.org/wiki/Cauchy's_integral_formula>`_
+
+Each is provided in the three precision modes, double, fixed multiple, and adaptive.  Since we are using the adaptive tracker in this tutorial, we will of course use the adaptive endgame.  I really like the Cauchy endgame, so we're in the land of the ``pybertini.endgame.AMPCauchyEG``.
+
+To make an endgame, we need to feed it the tracker that is used to run.  There are also config structs to play with, that control the way things are computed.
+
+::
+
+	eg = pybertini.endgame.AMPCauchyEG(tr)
+
+Since the endgame hasn't been run yet things are empty and default::
+
+	assert(eg.cycle_number()==0)
+	assert(eg.final_approximation()==pybertini.VectorXmp())
+
+The endgames are used by invoking ``run``, feeding it the point we are tracking on, the time we are at, and the time we want to track to.

+We can indeed do homotopy continuation with a non-algebraic systems.  What we cannot do is form a start system that we can guarantee will track to all solutions of the target system.  (because of things like :math:`\sin(x)` having infinitely many solutions, etc)
+
+:: 
 
 	del sys #we mal-formed our system above by adding too many functions, and non-polynomial functions to it.
 	# so, we start over
 	sys = pybertini.System()
 	sys.add_variable_group(grp)

+
+
+
+Forming a start system
+=========================
+
+To solve our algebraic system ``sys``, we need a corresponding start system -- one with related structure, but that is actually solvable without too much trouble.  Bertini2 has several implemented options.  The most basic (easiest to form and solve) start system is the Total Degree (TD) start system.  It is implemented as a first-class object in Bertini and PyBertini.  It takes in a polynomial system as its argument, and self-forms.
+
+
+Above, we formed a target system, ``sys``.  Now, let's make a start system ``td``.  Later, we will couple it to ``sys``.
+It's trivial to make a total degree start system (:class:`~pybertini.system.start_system.TotalDegree`): ::
 
 	td = pybertini.system.start_system.TotalDegree(sys)
 
-Wonderful, now we have an easy-to-solve system, the structure of which mirrors that of our target system.  Every start system comes with a method for generating its start points, by integer index.::
+Note that you have to pass in the target system into the constructor of the total degree, or you get an error.
 
-	# generates the 1th (0-based offsets in python) start point
-	# at double precision
-	td.start_point_d(1)
 
-	# generate the 1th point at current multiple precision
-	sp = td.start_point_mp(1)
-	assert(pybertini.default_precision() == sp[1].precision())
+Wonderful, now we have an easy-to-solve system ``td``, the structure of which mirrors that of our target system.  Every start system comes with a method ``start_point_*`` for generating its start points, by integer index.
 
-Finally, we couple ``sys`` and ``td``::
+::
+	
+	# generate the 1th (0-based offsets in python) start point
+	sp_d = td.start_point_d(1)# at double precision
+	
+	sp_mp = td.start_point_mp(1) # generate the 1th point at current default multiple precision
+	assert(pybertini.default_precision() == sp_mp[1].precision())
 
-	t = pybertini.function_tree.symbol.Variable("t")
-	homotopy = (1-t)*sys + t*td
-	homotopy.add_path_variable(t)
 
-Now, we have the minimum theoretical ingredients for solving a polynomial system using Numerical Algebraic Geometry: a homotopy, a target system, and a start system.
+Forming a homotopy
+==================
+
+
+We turn next to the act of path tracking.  This is the core computational method of numerical algebraic geometry, and it requires a continuous deformation between systems, called a "homotopy".  
+
+A homotopy in Numerical Algebraic Geometry glues together a start system and a target system, such that we can later "continue" from one into the other.   Observe:
+
+
+We couple ``sys`` and ``td``::
+
+	t = pybertini.Variable("t")     # make a path variable
+	homotopy = (1-t)*sys + t*td     # glue
+	homotopy.add_path_variable(t)   # indicate the path var
+
+Now, we have the minimum theoretical ingredients for solving a polynomial system using Numerical Algebraic Geometry: 
+
+#. a homotopy ``homotopy``, 
+#. a target system ``sys``, 
+#. and a start system ``td``.
+
+as well as a few other incidentals which will be implicitly used, such as a path variable ``t``.
+
 
 Tracking a single path
 ======================
 
 There are three basic trackers available in PyBertini:
 
-#. Fixed double precision: ``pybertini.tracking.DoublePrecisionTracker``
-#. Fixed multiple precision: ``pybertini.tracking.MultiplePrecisionTracker``
-#. Adaptive precision: ``pybertini.tracking.AMPTracker``
+
+#. Fixed double precision: :class:`~pybertini.tracking.DoublePrecisionTracker`
+#. Fixed multiple precision: :class:`~pybertini.tracking.MultiplePrecisionTracker`
+#. Adaptive precision: :class:`~pybertini.tracking.AMPTracker`
 
 Each brings its own advantages and disadvantages.  And, each has its ambient numeric type.

-Building PyBertini
+🛠 Building PyBertini
 *******************
 
 This part is unsatisfactory to me.  I really wish the package would just detect dependencies, and build itself.  However, since there is a C++ library behind it, this is not yet implemented.  For now, you have to configure, compile, and install yourself.

 🛠 Building PyBertini
-*******************
+****************************
 
 This part is unsatisfactory to me.  I really wish the package would just detect dependencies, and build itself.  However, since there is a C++ library behind it, this is not yet implemented.  For now, you have to configure, compile, and install yourself.

 The definitive resource for Bertini 1 is the book :cite:`bertinibook`.  While the way we interact with Bertini changes from version 1 to version 2, particularly when using PyBertini, the algorithms remain fundamentally the same.  So do most of the ways to change settings for the path trackers, etc.  We believe that embracing the flexibility of Python3 with PyBertini allows for much greater flexibility.  It also will relieve the user from the burden of input and output file writing and parsing.  Instead, computed results are returned directly to the user.

Subject: [PATCH 262/944] add git commit number to footer of pybertini docs

the documentation now depends on gitpython -- though sphinx will merely fail to generate the version numbers if it is not present.
thanks to

 Background
 ==============
 
+Polynomial systems often have singular solutions.  In numerical algebraic geometry, we want to compute all solutions, even the challenging singular ones.  The normal method of homotopy continuation with straight-line tracking fails to compute such roots, because tracking to a place where the Jacobian is non-invertible using methods that require inverting the Jacobian is doomed to fail [#]_.  
+
+So, if we can't track to a singular solution, but we still want to track to compute them, what are we to do?  We track around them, or near them, but not actually to them.  These methods are collectively called *endgames*, a term coined to evoke a sense of chess :cite:`morgan1990computing` :cite:`morgan1992computing` :cite:`morgan1992power`.  Thanks, Andrew Sommese, Charles Wampler, and Alexander Morgan, for everything you have given our community.

 So, if we can't track to a singular solution, but we still want to track to compute them, what are we to do?  We track around them, or near them, but not actually to them.  These methods are collectively called *endgames*, a term coined to evoke a sense of chess :cite:`morgan1990computing` :cite:`morgan1992computing` :cite:`morgan1992power`.  Thanks, Andrew Sommese, Charles Wampler, and Alexander Morgan, for everything you have given our community.
 
+Endgames represent a way to finish a tracking of a path, when the endpoint is possibly singular.  Rather than track all the way to the endtime, you instead run an endgame that uses mathematical theory to compute the root.
 
+Endgames in PyBertini
+==========================
 
+An endgame is a computational tool that one does in the final stage of a path track to a possibly singular root.  There are two implemented endgames in Bertini:
 
-Application
-=============
+#. Power series (PSEG) -- uses `Hermite interpolation <https://en.wikipedia.org/wiki/Hermite_interpolation>`_ across a sequence of geometrically-spaced points (in time) to extrapolate to a target time :cite:`morgan1992power`. 
+#. Cauchy (CauchyEG)-- uses `Cauchy's integral formula <https://en.wikipedia.org/wiki/Cauchy's_integral_formula>`_ in a sequence of circles about the root you are computing.  
 
-There are two implemented endgames in Bertini:
+Both try to compute the cycle number :math:`c` for the root.  In PSEG, :math:`c` is used as the degree of a Hermite interpolant used to extrapolate to 0.  In CauchyEG,  it is used for the number of cycles to walk before doing a trapezoid-rule integral.
 
-#. Power series -- uses `Hermite interpolation <https://en.wikipedia.org/wiki/Hermite_interpolation>`_ across a sequence of geometrically-spaced points (in time) to extrapolate to a target time.
-#. Cauchy -- uses `Cauchy's integral formula <https://en.wikipedia.org/wiki/Cauchy's_integral_formula>`_
+Each is provided in the three precision modes, double, fixed multiple, and adaptive.  Since we are using the :class:`~pybertini.tracking.AMPTracker` in this tutorial, we will of course use the adaptive endgame.  I really like the Cauchy endgame, so we're in the land of the :class:`~pybertini.endgame.AMPCauchyEG`.

Subject: [PATCH 291/944] fixed bug coming from `auto` and expressions of
 `mpfr_complex` not playing nice

that is, an expression of `mpfr_complex` stored into an `auto` variable generates `nan`s.  take note.

Subject: [PATCH 295/944] rand(mpfr,digits) --> rand_assign(mpfr,digits)

made it clear when a random number is being used to assign, by being explicit.

also,
* enhancements to the random number generation (which admittedly still sucks)
* an optimization to precision changing of patches
* added a few tests, which currently fail.  6 total tests fail in basics at this time.  the root is in bmp, so i have to wait.  bmp issues 60-62 or so are mine, related to these failing tests.

Subject: [PATCH 303/944] trying to make custom_complex syntactically
 equivalent to the new boost::multiprecision::complex

the big change is that precision of existing variables is preserved in assignment.  this is currrently **not** the case for the custom type, though it needs to be to be equivalent.

* added another test on precision through arithemetic

 // i took this check out jan 27, 2018.  the tracker's precision literally cannot be adjusted as currently written.  hence, there's no way to correct a failing test like this.  i do hope there isn't something nasty lurking about causing it to fail, but causing other problems as well.  i guess it would be nice if the tracker came back in the same precision as the endgame result, but ... do i really care?  if i did, i would have to add a ChangePrecision(p) method to all flavors of trackers, but that's not really what they do...  they're a tool, and adjust precision according to the input they receive, just like the endgames, and other things.

Subject: [PATCH 316/944] tweaks to get things compiling using a current
 Boost.Multiprecision clone.

does it work with older versions?  untested.  that's next.

please note that some small number of precision-through-arithmetic, in mixed precision not at default, tests fail when not using the new Boost.Multiprecision mpc_complex type.  oh well, they're rather inconsequential to me right now.  i *did* ask for help on them, but we'll see if it works out.  who knows.

-			## Input: 
-				target_system: System that we wish to solve. Using this we can know total number of variables, functions, and variable groups,
-				 by using the systems member functions. 
-				variable_group_counter: This vector of integers will keep track of how many times we can pick from a column.
-				row: This is the row in GenerateValidPartitions(). 
-				column: This comes from current_partition[row] in GenerateValidPartitions(). Because of this we will walk through the 
-				degree matrix from left to right.  
-
-
-			## Output:
-					int col: Returns the column that we have chosen for a given row. 
-
-
-			##Details:
-					Given a row, we search for a valid column from left to right. Since column is defaulted to -1 we will start with 
-					col = 0. Variaable_group_counter will be incremented or decremented if we are coming off a good partition, or have found a 
-					good column.

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
+#   or '14' (for the C++14 standard).
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for no added switch, and then for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

-# SYNOPSIS
-#
-#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the C++11
-#   standard; if necessary, add switches to CXXFLAGS to enable support.
-#
-#   The first argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-#   -std=c++11).  If neither is specified, you get whatever works, with
-#   preference for an extended mode.
-#
-#   The second argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline C++11 support is required and that the macro
-#   should error out if no mode with that support is found.  If specified
-#   'optional', then configuration proceeds regardless, after defining
-#   HAVE_CXX11 if and only if a supporting mode is found.

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
+#   or '14' (for the C++14 standard).
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for no added switch, and then for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

 # SYNOPSIS
 #
-#   AX_CXX_COMPILE_STDCXX_14([ext|noext],[mandatory|optional])
+#   AX_CXX_COMPILE_STDCXX_14([ext|noext], [mandatory|optional])
 #
 # DESCRIPTION
 #
 #   Check for baseline language coverage in the compiler for the C++14
-#   standard; if necessary, add switches to CXXFLAGS to enable support.
+#   standard; if necessary, add switches to CXX and CXXCPP to enable
+#   support.
 #
-#   The first argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++14) or a strict conformance mode (e.g.
-#   -std=c++14).  If neither is specified, you get whatever works, with
-#   preference for an extended mode.
-#
-#   The second argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline C++14 support is required and that the macro
-#   should error out if no mode with that support is found.  If specified
-#   'optional', then configuration proceeds regardless, after defining
-#   HAVE_CXX14 if and only if a supporting mode is found.
+#   This macro is a convenience alias for calling the AX_CXX_COMPILE_STDCXX
+#   macro with the version set to C++14.  The two optional arguments are
+#   forwarded literally as the second and third argument respectively.
+#   Please see the documentation for the AX_CXX_COMPILE_STDCXX macro for
+#   more information.  If you want to use this macro, you also need to
+#   download the ax_cxx_compile_stdcxx.m4 file.

Subject: [PATCH 379/944] finally answering the question about limbo

splitting the contents of limbo.*pp into various files, then renaming it so that it's just have_bertini.hpp.  this will make checking for bertini's library very easy, with no need to include all libraries.  maybe that's a bad thing?  i dunno.  i just don't want to make EIGEN_CPPFLAGS have to show up magically in AX_BERTINI2.

whatever.  this isn't a compiling commit -- some include stuff is broken in the make setup.

Subject: [PATCH 394/944] nodes are visitable!

* Probably visitable, no promises.  no tests impemented yet.
* also, i removed a dead code file (diff_linear.hpp, the content of which was already in linear_product.hpp.  also, the header which I removed had old non-functional code.  good riddance!)

Subject: [PATCH 407/944] corrections to mistakes preventing compilation of the
 core.

mostly off-by-pointer, use of Python syntax during initial code authorship, or forgotten `_`.  all of the finds were erroneous, fixed 'em.  a few forgotten types of things.

Subject: [PATCH 430/944] enabled shared_from_this across all node types

the only one that had it was `Variable`, and we're gonna need it for some SLP ops.  at the very least, it's good to have this functionality.

we had been using the `signs` incorrectly -- there's actually one sign per operand, indicating what the sign in the sum is.  so, if the first sign is negative (false), then we start by negating.

it's very likely the multiplication/division operator's visit is incorrect, cuz I think I was making the same mistake.

Subject: [PATCH 491/944] working towards reliable tests

- added scoped options to bertini namespace
- added a test that setting default precision options actually affects the current thread.  (it doesn't in Boost 1.82 and below, see issue 551 in Boost.Multiprecision)
- adjusted failing tests
- added a bunch of tests for various precision policies.

still have failing tests for complex numbers.  analysis paralysis has me!

Subject: [PATCH 494/944] it's amazing, now can make a zerodim algorithm in
 python

but only double precision, total degree.  working on it!

also, you can solve but you can't do anything with the solutions.  so a long way to go.  still, this is progress.

Subject: [PATCH 508/944] removed minieigen, removed doubleprecision submodule,
 etc

a big set of changes, touching much of the code.  tests are probably still broken cuz there's likely still some `mi.whatever` stuff in there, but this is the best I can do for now.  more in future. commits.

-The `MiniEigen <https://github.com/eudoxos/minieigen>`_ submodule, for PyBertini
-
-Bertini2 uses `Eigen <https://eigen.tuxfamily.org/>`_ for linear algebra, enabling expression templates on linear algebraic objects and operations for arbitrary types -- most importantly the multiprecision complex numbers needed for working near singularities in algebraic geometry.
-
-This module exposes some functionality.  Not near all of Eigen is exposed.  We could use help on this.  If you know some Boost.Python and some Eigen, please consider helping expose more of Eigen through MiniEigen.  Bertini2 is not the host of MiniEigen -- user Eudoxus on GitHub provided MiniEigen.
-
-If you encounter any problems with this functionality, please ask for help via a `GitHub issue <https://github.com/bertiniteam/b2/issues>`_.

Subject: [PATCH 510/944] rewrote tests using numpy instead of minieigen

because i removed minieigen.  but now function signatures don't match.  i asked for help from the eigenpy people at https://github.com/stack-of-tasks/eigenpy/issues/378, since they've likely solved this problem and there's a model of it in their codebase somewhere

Subject: [PATCH 520/944] improved exception message

helped reveal that i need to change something.  using the zerodim algo with a sys breaks dehomogenization because the system gets homogenized, but since storage policy is clone, it doesn't affect the original system, and ...  yeah, things aren't lining up.

ugh, this workaround *blows*.  this needs to be in the core, not out here.  boo to whatever happened that led to this.

todo: replace pass by ref via & with Eigen::Ref.  (i tried once a week ago and failed)

Subject: [PATCH 543/944] a checkpoint towards SLP

not really functional, but i need a checkpoint towards.  I'm realizing that I really need two flags for methods for systems:
* one for evaluation (function tree / SLP),
* one for differentiation method (jacobians as implemented by Jeb, or plain old differentiation as implemented by me)

this checkpoint adds
* a flag for SLP's for whether they're evaluated
* naming clarifications (InPlace)
* switch cases for eval method (though these will all have to change as i take next steps as described above)

now they're nested 🪺

i had to change a few signatures for get-by-reference from Martix<Derived> to just Vec<T>.  this whole part of the code is bothersome, anyway.  it should be Eigen::Ref's if we want to not have to wrap these calls for EigenPy...

the core library compiled.  class test compiled.  tracking_basics_test compiled.

next steps: get failing tests to pass.

Subject: [PATCH 548/944] changes towards SLP's being useful

oh, so many failing tests.

notable changes:
* changes in signatures for in-place functions, and some naming changes to make it more clear that in-place is happening.
* a few new tests
* printing of opcodes for slp's
* removed an incorrect output values location in slp
* from templated `Derived` style to Vec, in an effort to changing to using Eigen::Ref<> for output in-place operations
* removed resizing operations in SLP in-place ops.  Convention: in-place ops won't resize the container for you since Eigen won't allow it.

Subject: [PATCH 549/944] added back a copy of current variable values even for
 SLP

probably the patch should just share `current_variable_values_` by reference...  that would avoid the copy!

Subject: [PATCH 551/944] NumFunctions --> NumTotalFunctions

i was having such a hard time dealing with sizes of things that I made this decision: be more explicit about what functions.  Total includes patches.  Natural doesn't.

There are still inconsistencies between function and variable quantifier naming conventions

Subject: [PATCH 564/944] added explicit setting of eval method

these tests depend on eval method to be FunctionTree.  this is a side-effect of setting variable values NOT propagating to the Node variables when eval method is SLP. Like, you're using an SLP.

down to 8 failures, but I want to re-write the differentiate and differentiate_wrt_var test suites to be much more explicit and thorough.  right now the suites use Systems to wrap around, and the systems and parsed from strings using classic parser.  but this is testing more than just differentiation.  it needs to be separated.

Subject: [PATCH 572/944] factory methods for making shared_ptr to nodes, and
 improved serialization

this solves a bug where bad weak pointers after de-serializing a System.  The solution was simple enough: move `enable_shared_from_this` to the base class.  I also had to do a bit to solve the diamond problem.

constructors are private now.  you must use the public factory method `Make` to make nodes, so that they always come from a shared pointer.  I anticipate that another revision of this will happen, to force them to come from a particular memory pool / manager.  but not now.

Subject: [PATCH 574/944] accommodated the "private constructor" pattern,
 manually added inits using `Make`

I had made all constructors private, and this broke compilation in Python.

There's still a problem: I think my use of Factory breaks ownership, and objects made via Factory cause bad de-allocation at the end of Python.  In particular, I get this error:

```
Fatal Python error: PyThreadState_Get: the function must be called with the GIL held, but the GIL is released (the current Python thread state is NULL)
Python runtime state: finalizing (tstate=0x00000001057fe0c8)
```

Backtracing reveals it's de-allocation.  So I think Python and Factory are fighting for ownership.  I'm removing Factory.

-\brief Methods for producing nodes of various types. 
-
-These wrapper functions are intended to be re-written to use something like a workspace, sometime in the future.  This will allow one to refer to things like the `1` node, or the `pi` node, or the `f2` node.  Other desired functionality is things like inspecting all declared symbols or variables, or having multiple workspaces.

Subject: [PATCH 576/944] moved from C++14 to C++17

this does NOT solve the problem with eigen pointers being aligned.  specifically, i'm getting this assert from EigenPy:

```
Assertion failed: (is_aligned(raw_ptr, EIGENPY_DEFAULT_ALIGN_BYTES) && "The pointer is not aligned."), function allocate, file eigen-allocator.hpp, line 229.
Abort trap: 6
```

when I pass an Eigen container in Python back into function expecting an Eigen container.

Subject: [PATCH 598/944] commented out lines that just weren't working for me

they cause install errors because the files don't go to the right places.  leave it to pip.

this was a remnant of an effort to get autotools to correctly make a distfile, so we could use it with conda.  fail.  we're working on replacing autotools with cmake, but this is work in progress.

sorry for the noise.

-# SYNOPSIS
-#
-#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-#
-# DESCRIPTION
-#
-#   Test for the Boost C++ libraries of a particular version (or newer)
-#
-#   If no path to the installed boost library is given the macro searchs
-#   under /usr, /usr/local, /opt, /opt/local and /opt/homebrew and evaluates
-#   the $BOOST_ROOT environment variable. Further documentation is available
-#   at <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
-#
-#   And sets:
-#
-#     HAVE_BOOST

-# SYNOPSIS
-#
-#   AX_BOOST_SYSTEM
-#
-# DESCRIPTION
-#
-#   Test for System library from the Boost C++ libraries. The macro requires
-#   a preceding call to AX_BOOST_BASE. Further documentation is available at
-#   <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_SYSTEM_LIB)
-#
-#   And sets:

-# SYNOPSIS
-#
-#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the specified
-#   version of the C++ standard.  If necessary, add switches to CXX and
-#   CXXCPP to enable support.  VERSION may be '11', '14', '17', or '20' for
-#   the respective C++ standard version.
-#
-#   The second argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-#   -std=c++11).  If neither is specified, you get whatever works, with
-#   preference for no added switch, and then for an extended mode.
-#
-#   The third argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline support for the specified C++ standard is
-#   required and that the macro should error out if no mode with that
-#   support is found.  If specified 'optional', then configuration proceeds
-#   regardless, after defining HAVE_CXX${VERSION} if and only if a
-#   supporting mode is found.

-# SYNOPSIS
-#
-#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-#
-# DESCRIPTION
-#
-#   Test for the Boost C++ libraries of a particular version (or newer)
-#
-#   If no path to the installed boost library is given the macro searches
-#   under /usr, /usr/local, /opt, /opt/local and /opt/homebrew and evaluates
-#   the $BOOST_ROOT environment variable. Further documentation is available
-#   at <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
-#
-#   And sets:
-#
-#     HAVE_BOOST

-# SYNOPSIS
-#
-#   AX_BOOST_PYTHON
-#
-# DESCRIPTION
-#
-#   This macro checks to see if the Boost.Python library is installed. It
-#   also attempts to guess the correct library name using several attempts.
-#   It tries to build the library name using a user supplied name or suffix
-#   and then just the raw library.
-#
-#   If the library is found, HAVE_BOOST_PYTHON is defined and
-#   BOOST_PYTHON_LIB is set to the name of the library.
-#
-#   This macro calls AC_SUBST(BOOST_PYTHON_LIB).
-#
-#   In order to ensure that the Python headers and the Boost libraries are
-#   specified on the include path, this macro requires AX_PYTHON_DEVEL and
-#   AX_BOOST_BASE to be called.

-# SYNOPSIS
-#
-#   AX_BOOST_UNIT_TEST_FRAMEWORK
-#
-# DESCRIPTION
-#
-#   Test for Unit_Test_Framework library from the Boost C++ libraries. The
-#   macro requires a preceding call to AX_BOOST_BASE. Further documentation
-#   is available at <http://randspringer.de/boost/index.html>.
-#
-#   This macro calls:
-#
-#     AC_SUBST(BOOST_UNIT_TEST_FRAMEWORK_LIB)
-#
-#   And sets:
-#
-#     HAVE_BOOST_UNIT_TEST_FRAMEWORK

-# SYNOPSIS
-#
-#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the specified
-#   version of the C++ standard.  If necessary, add switches to CXX and
-#   CXXCPP to enable support.  VERSION may be '11', '14', '17', or '20' for
-#   the respective C++ standard version.
-#
-#   The second argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-#   -std=c++11).  If neither is specified, you get whatever works, with
-#   preference for no added switch, and then for an extended mode.
-#
-#   The third argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline support for the specified C++ standard is
-#   required and that the macro should error out if no mode with that
-#   support is found.  If specified 'optional', then configuration proceeds
-#   regardless, after defining HAVE_CXX${VERSION} if and only if a
-#   supporting mode is found.

-# ===========================================================================

-#
-# SYNOPSIS
-#
-#   AX_PYTHON_DEVEL([version[,optional]])
-#
-# DESCRIPTION
-#
-#   Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
-#   in your configure.ac.
-#
-#   This macro checks for Python and tries to get the include path to
-#   'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output
-#   variables. It also exports $(PYTHON_EXTRA_LIBS) and
-#   $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
-#
-#   You can search for some particular version of Python by passing a
-#   parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
-#   note that you *have* to pass also an operator along with the version to
-#   match, and pay special attention to the single quotes surrounding the
-#   version number. Don't use "PYTHON_VERSION" for this: that environment
-#   variable is declared as precious and thus reserved for the end-user.
-#
-#   By default this will fail if it does not detect a development version of
-#   python.  If you want it to continue, set optional to true, like
-#   AX_PYTHON_DEVEL([], [true]).  The ax_python_devel_found variable will be
-#   "no" if it fails.
-#
-#   This macro should work for all versions of Python >= 2.1.0. As an end
-#   user, you can disable the check for the python version by setting the
-#   PYTHON_NOVERSIONCHECK environment variable to something else than the
-#   empty string.
-#
-#   If you need to use this macro for an older Python version, please
-#   contact the authors. We're always open for feedback.

Subject: [PATCH 626/944] fixed the bug causing the alignment crash

all I had to do was make sure to take an `Eigen::Ref<Vec<T>>` instead of `Vec<T> const&`.  It was that simple.  It took me wayyyyyyy ttoooooo lonoooonononggg to fix that issue.  But I did it.

I also cleaned up a bit of stuff in the code while I was at it.

Subject: [PATCH 627/944] added a basic test suite for testing numpy
 functionality with custom types

many of these tests still fail, and they'll continue to fail until some changes to EigenPy percolate down to me.

Subject: [PATCH 629/944] refactor towards a complete build system

this is a non-working commit, because finding numpy fails when using `pip install .` from the top level.  BUT, it does compile all-at-once (core lib, bindings) with one cmake && make call from top-level, which is a significant improvement.

* split the pure-python wrapper library from the compiled bindings
* moved the `cmake` directories up a level so can maintain only one copy of those files
* worked on generating the cmake files to find `libbertini2`, rather than maintaining my own such file.

-Installation Instructions
-*************************
-

-Software Foundation, Inc.

-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell command './configure && make && make install'
-should configure, build, and install this package.  The following
-more-detailed instructions are generic; see the 'README' file for
-instructions specific to this package.  Some packages provide this
-'INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The 'configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a 'Makefile' in each directory of the package.
-It may also create one or more '.h' files containing system-dependent
-definitions.  Finally, it creates a shell script 'config.status' that
-you can run in the future to recreate the current configuration, and a
-file 'config.log' containing compiler output (useful mainly for
-debugging 'configure').
-
-   It can also use an optional file (typically called 'config.cache' and
-enabled with '--cache-file=config.cache' or simply '-C') that saves the
-results of its tests to speed up reconfiguring.  Caching is disabled by
-default to prevent problems with accidental use of stale cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how 'configure' could check whether to do them, and mail
-diffs or instructions to the address given in the 'README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point 'config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file 'configure.ac' (or 'configure.in') is used to create
-'configure' by a program called 'autoconf'.  You need 'configure.ac' if
-you want to change it or regenerate 'configure' using a newer version of
-'autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. 'cd' to the directory containing the package's source code and type
-     './configure' to configure the package for your system.
-
-     Running 'configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type 'make' to compile the package.
-
-  3. Optionally, type 'make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type 'make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the 'make install' phase executed with root
-     privileges.
-
-  5. Optionally, type 'make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior 'make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing 'make clean'.  To also remove the
-     files that 'configure' created (so you can compile the package for
-     a different kind of computer), type 'make distclean'.  There is
-     also a 'make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type 'make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide 'make
-     distcheck', which can by used by developers to test that all other
-     targets like 'make install' and 'make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the 'configure' script does not know about.  Run './configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give 'configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here is
-an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU 'make'.  'cd' to the
-directory where you want the object files and executables to go and run
-the 'configure' script.  'configure' automatically checks for the source
-code in the directory that 'configure' is in and in '..'.  This is known
-as a "VPATH" build.
-
-   With a non-GNU 'make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use 'make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple '-arch' options to the
-compiler but only a single '-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the 'lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, 'make install' installs the package's commands under
-'/usr/local/bin', include files under '/usr/local/include', etc.  You
-can specify an installation prefix other than '/usr/local' by giving
-'configure' the option '--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like '--bindir=DIR' to specify different values for particular
-kinds of files.  Run 'configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the default
-for these options is expressed in terms of '${prefix}', so that
-specifying just '--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
-   The most portable way to affect installation locations is to pass the
-correct locations to 'configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-'make install' command line to change installation locations without
-having to reconfigure or recompile.
-
-   The first method involves providing an override variable for each
-affected directory.  For example, 'make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-'${prefix}'.  Any directories that were specified during 'configure',
-but not in terms of '${prefix}', must each be overridden at install time
-for the entire installation to be relocated.  The approach of makefile
-variable overrides for each directory variable is required by the GNU
-Coding Standards, and ideally causes no recompilation.  However, some
-platforms have known limitations with the semantics of shared libraries
-that end up requiring recompilation when using this method, particularly
-noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the 'DESTDIR' variable.  For
-example, 'make install DESTDIR=/alternate/directory' will prepend
-'/alternate/directory' before all installation names.  The approach of
-'DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of '${prefix}'
-at 'configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving 'configure' the
-option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
-
-   Some packages pay attention to '--enable-FEATURE' options to
-'configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to '--with-PACKAGE' options, where PACKAGE
-is something like 'gnu-as' or 'x' (for the X Window System).  The
-'README' should mention any '--enable-' and '--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, 'configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the 'configure' options '--x-includes=DIR' and
-'--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of 'make' will be.  For these packages, running './configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with 'make V=1'; while running './configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with 'make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
-is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX 'make' updates targets which have the same timestamps as their
-prerequisites, which makes it generally unusable when shipped generated
-files such as 'configure' are involved.  Use GNU 'make' instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
-workaround.  If GNU CC is not installed, it is therefore recommended to
-try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
-in your 'PATH', put it _after_ '/usr/bin'.
-
-   On Haiku, software installed for all users goes in '/boot/common',
-not '/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features 'configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, 'configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-'--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as 'sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file 'config.sub' for the possible values of each field.  If
-'config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option '--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with '--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for 'configure' scripts to share,
-you can create a site shell script called 'config.site' that gives
-default values for variables like 'CC', 'cache_file', and 'prefix'.
-'configure' looks for 'PREFIX/share/config.site' if it exists, then
-'PREFIX/etc/config.site' if it exists.  Or, you can set the
-'CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all 'configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to 'configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the 'configure' command line, using 'VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified 'gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
-Autoconf limitation.  Until the limitation is lifted, you can use this
-workaround:
-
-     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-'configure' Invocation
-======================
-
-   'configure' recognizes the following options to control how it
-operates.
-
-'--help'
-'-h'
-     Print a summary of all of the options to 'configure', and exit.
-
-'--help=short'
-'--help=recursive'
-     Print a summary of the options unique to this package's
-     'configure', and exit.  The 'short' variant lists options used only
-     in the top level, while the 'recursive' variant lists options also
-     present in any nested packages.
-
-'--version'
-'-V'
-     Print the version of Autoconf used to generate the 'configure'
-     script, and exit.
-
-'--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
-     disable caching.
-
-'--config-cache'
-'-C'
-     Alias for '--cache-file=config.cache'.
-
-'--quiet'
-'--silent'
-'-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to '/dev/null' (any error
-     messages will still be shown).
-
-'--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     'configure' can determine that directory automatically.
-
-'--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names:: for
-     more details, including other options available for fine-tuning the
-     installation locations.
-
-'--no-create'
-'-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-'configure' also accepts some other, not widely useful, options.  Run
-'configure --help' for more details.

-As a user, skip to step 2.  as a developer, to compile this project, you need to
-
-1) Regenerate the configure script, and some other m4 macros, etc, so that the build system is complete.  This requires the autotools, modern versions.  The command for this is
-
-autoreconf -vfi
-
-The -vfi flags are for (v)erbose, (f)orce, and (i)nstall.  If this step fails, you almost certainly have outdated autotools software, most namely automake, autoconf, and libtool.  Update your tools as necessary.
-
-On Linux machines, you may have to run the command
-
-libttoolize
-
-in order to get autoreconf to work.
-
---------------
-
-As a user, or maintainer, engage in the standard build process for any software built using the autotools.
-
-2) ./configure (with your options)
-
-3) make
-
-Then, if you want to, you can run the test programs.  So far, there is one: b2_class_test.  It is built using the Boost.UnitTest library, and can produce a variety of output files, and be run in a variety of modes.  These options are not documented here.
-
--------------
-
-notes:
-
-If you add files to the project, or wish to add a compiled program, etc, you modify the b2/core/Makefile.am, and a b2/core/path/to/Makemodule.am file, or possibly create a Makemodule.am file at the correct location.  If you need help with this, please contact Dani Brake brakeda@uwec.edu
-
-Please do not commit autotools-built files to the repository, including the configure script, any file in the created b2/core/config/ folder, or the others.  There is a chance you may have to add a m4 macro or something, and this is ok.  Do what you need, but commit only the source files, not generated files.
-
-Please maintain this file by editing it as necessary.

Subject: [PATCH 633/944] renamed the python library to just `bertini`

i was sick of seeing `py` at the front.  like, i know it's python, you don't need to tell me that.

also updated a bunch of copyright years and worked on a bit of documentation

-### Important note on cloning
-
-The recommended method for getting the code for Bertini 2 is to clone from command line using git:

-`git clone https://github.com/bertiniteam/b2 --recursive`
-
-This ensures that any other repo's we depend on get cloned into their correct locations.

-This README contains brief instructions for how to build the core of Bertini2.  For more extensive instructions, visit the wiki for the GitHub repo: https://github.com/bertiniteam/b2/wiki

-BUILDING THE CORE OF BERTINI2 
-
--------------
-
-Before getting started, please note that these instructions are for Linux and Mac only.  Windows build instructions are yet to come.  If you want to help write those instructions (and indeed create the process), please let the devteam know!
-
--------------
-
-Prerequisites:
-
-- Compiler capable of compiling C++ code using C++14 features.
-- Eigen 3.2.x or later.
-- Boost 1.56 or later.  To take advantage of expression templates for multiprecision real numbers (an important optimization), Boost versions prior to 1.61 must be patched.  See https://github.com/boostorg/multiprecision/commit/f57bd6b31a64787425ec891bd2ceb536c9036f72  If you do not wish to patch Boost, and are using a version prior to 1.61, please disable expression templates when configuring.  If you don't, you'll see a pair of errors, and comments basically saying this same message.  The configure flag is --disable-expression_templates.
-- Plenty of RAM.  Since there are many templates in play in Bertini2, Eigen, and Boost, compilation is slower than Bertini1, and takes a lot of memory.  GCC (g++) tends to use around 1 GB per thread when compiling the core, Clang perhaps 250MB.  Plan your use of parallel make accordingly, and consider getting a cup of coffee while compiling.  Enjoy!
-
--------------
-
-Steps to compile:
-
--------------
-
-1) Generate the ./configure script, and some other m4 macros, etc, so that the build system is complete.  This requires the autotools, modern versions.  The command for this is
-
-		autoreconf -vfi
-
-The -vfi flags are for (v)erbose, (f)orce, and (i)nstall.  If this step fails, you almost certainly have outdated autotools software, most namely automake, autoconf, and libtool.  Update your tools as necessary.
-
-Important note: on Linux machines, you typically have to run the command
-
-		libtoolize
-
-in order to get autoreconf to work.  
-
---------------
-
-2) Engage in the standard build process for any software built using the autotools.
-
-		./configure (with your options)
-
-		make (consider using multiple threads [-j #] if you have enough memory)
-
-Then, if you want to, you can run the test programs.  
-
-		make check  (again consider running in parallel)
-
-The test programs are built using the Boost.UnitTest library, and can produce a variety of output files, and be run in a variety of modes.  These options are not documented here.  Rather, if you ask for --help on them, they will tell you more.
-
-Finally, you probably want to install the core, particularly if you intend to build the Python bindings (b2/python).
-
-		[sudo] make install
-
--------------
-
-Notes for developers:
-
-If you add files to the project, or wish to add a compiled program, etc, you modify the b2/core/Makefile.am, and a b2/core/path/to/Makemodule.am file, or possibly create a Makemodule.am file at the correct location.  If you need help with this, please contact Silviana Amethyst amethyst@uwec.edu
-
-Please do not commit autotools-built files to the repository, including the configure script, any file in the created b2/core/config/ folder, or the others.  There is a chance you may have to add a m4 macro or something, and this is ok.  Do what you need, but commit only the source files, not generated files.
-
-Please maintain this file by editing it as necessary.

+The library uses templates heavily, and is written to use the C++17 standard (most of the code is up to C++14, but there are a few 17 things in there).
+
+For compilation instructions, see [the Wiki compiling section on Github](https://github.com/bertiniteam/b2/wiki/Compilation-Guide).

Subject: [PATCH 655/944] commented out using expression templates

linking fails due to manual template instantiation, so I had to turn off expression templates.

Note: in light testing, turning them on seemed to bring runtime down from ~17s to ~14s, for the `test_endgames` suite for the core.  So having them on DOES save significant time.

It looks like I will have to rewrite some of the core to make this happen, sadly.

Subject: [PATCH 657/944] update develop with ci branch (#1)

There are some compiling errors while being compiled in windows

* `size_t` is translated into `unsigned long` in linux, mac while `unsigned long long` in windows 10: `core/include/bertini2/eigen_extensions.hpp` and `core/test/classes/start_system_test.cpp` are modified
* use `clang` of LLVM in Windows since MSVC has different compiling way for `template`
* use `--no-isolation` for `scikit-build` in Windows

For linux wheel naming convention, we cannot use x86_64, x86_i386 anymore for pypi repository. https://peps.python.org/pep-0600/

* use `auditwheel` for it

-The bertini::CauchyEngame class enables us to finish tracking on possibly singular paths on an arbitrary square homotopy.  
+The bertini::CauchyEngame class enables us to finish tracking on possibly singular paths on an arbitrary square homotopy.
 The intended usage is to:
 1. Create a system, tracker, and instantiate some settings.

+4. For each path being tracked send the CauchyEndgame the time value and other variable values at that time.
 5. The CauchyEndgame, if successful, will store the target systems solution at $t = 0$.

Subject: [PATCH 691/944] Simple test (#2)

* chore: test for win32

* chore: use Release libraries for linking in windows

* chore: use 1e-14 instead of 1e-15

* 1e-15 doesn't work in windows

* chore: remove docker-compose.yml

* chore: revert test list

Moved cmake.args into the [tool.scikit-build.cmake] section to avoid
declaring the cmake key twice, which caused a parse error on Windows CI.

The conditional find_package(Boost COMPONENTS system) call for Boost < 1.89
was resetting Boost_LIBRARIES to only contain boost_system, causing the
linker to fail finding serialization, log, filesystem, etc. on Windows.
Re-find with all components so Boost_LIBRARIES remains complete.

jrl-cmakemodules creates a bertini2-doc target when Doxygen is found,
and on MSVC/clang-cl it's added to ALL so it builds unconditionally.
The Windows CI runner has Strawberry Perl's doxygen pre-installed,
causing the build to fail. CMAKE_DISABLE_FIND_PACKAGE_Doxygen=ON
prevents find_package(Doxygen) from finding it.

The manylinux build already installs eigenpy from source via cmake.
Without --no-deps, pip tries to install eigenpy from PyPI, which
pulls scipy from source requiring OpenBLAS compilation that fails.

On Eigen 3.3.x (manylinux2014), EIGEN_MAKE_ALIGNED_OPERATOR_NEW defines
operator new/delete. Placed in the private section, it made destructors
of derived classes (StartSystem, MHomogeneous, User) ill-formed.
Moving to public section fixes the access error.

- Move Boost and eigenpy builds outside Python version loop (built once)
- Add set -e for fail-fast behavior
- Add -j$(nproc) for parallel compilation
- Use glob for auditwheel instead of hardcoded version string
- Drop EOL Python versions (cp38-310), keep cp311-312
- Include both /usr/local/lib and lib64 in LD_LIBRARY_PATH

b2 auto-detects Python 2.7 from the manylinux2014 container and tries
to build Boost.Python for it, which fails (missing pyconfig.h).
Write a user-config.jam and pass python=<ver> to b2 to restrict
the build to only the target Python 3.11.

PYBIN is the bin/ directory (e.g., /opt/python/cp312-cp312/bin).
PYTHON_EXECUTABLE needs the actual binary, not the directory.

- Removed unescaped ${PYBIN}/${DIR} lines that the host shell expanded
  to empty before reaching the Docker container
- Replaced hardcoded pybertini-1.0a8 filename with glob pattern
- Use full path /io/wheelhouse/ for auditwheel input
- Escape $LD_LIBRARY_PATH so it resolves inside Docker
- Clean up wheelhouse between loop iterations

Subject: [PATCH 727/944] update develop with ci branch (#1)

There are some compiling errors while being compiled in windows

* `size_t` is translated into `unsigned long` in linux, mac while `unsigned long long` in windows 10: `core/include/bertini2/eigen_extensions.hpp` and `core/test/classes/start_system_test.cpp` are modified
* use `clang` of LLVM in Windows since MSVC has different compiling way for `template`
* use `--no-isolation` for `scikit-build` in Windows

For linux wheel naming convention, we cannot use x86_64, x86_i386 anymore for pypi repository. https://peps.python.org/pep-0600/

* use `auditwheel` for it

 \class CauchyEndgame
 \brief Class used to finish tracking paths during Homotopy Continuation.

 ## Explanation
-The bertini::CauchyEngame class enables us to finish tracking on possibly singular paths on an arbitrary square homotopy.  
+The bertini::CauchyEngame class enables us to finish tracking on possibly singular paths on an arbitrary square homotopy.
 The intended usage is to:
 1. Create a system, tracker, and instantiate some settings.
-2. Using the tracker created track to the engame boundary. 
+2. Using the tracker created track to the engame boundary.
 3. Create a CauchyEndgame, associating it to the system you are going to solve or track on.
-4. For each path being tracked send the CauchyEndgame the time value and other variable values at that time. 
+4. For each path being tracked send the CauchyEndgame the time value and other variable values at that time.
 5. The CauchyEndgame, if successful, will store the target systems solution at $t = 0$.
 
 
 
 ## Example Usage
-Below we demonstrate a basic usage of the CauchyEndgame class to find the singularity at $t = 0$. 
-The pattern is as described above: create an instance of the class, feeding it the system to be used, and the endgame boundary time and other variable values at the endgame boundary.

 		Since the Bertini trackers have common functionality, and we want to be able to call arbitrary algorithms using and tracker type, we use inheritance.  That is, there is common functionality in all trackers, such as

 		* TrackPath
 		* Refine

In particular, the fixed precision trackers produce and work in a fixed precision, whereas the AMPTracker varies precision to get around or near branch points while tracking.

Moved cmake.args into the [tool.scikit-build.cmake] section to avoid
declaring the cmake key twice, which caused a parse error on Windows CI.

The conditional find_package(Boost COMPONENTS system) call for Boost < 1.89
was resetting Boost_LIBRARIES to only contain boost_system, causing the
linker to fail finding serialization, log, filesystem, etc. on Windows.
Re-find with all components so Boost_LIBRARIES remains complete.

jrl-cmakemodules creates a bertini2-doc target when Doxygen is found,
and on MSVC/clang-cl it's added to ALL so it builds unconditionally.
The Windows CI runner has Strawberry Perl's doxygen pre-installed,
causing the build to fail. CMAKE_DISABLE_FIND_PACKAGE_Doxygen=ON
prevents find_package(Doxygen) from finding it.

The manylinux build already installs eigenpy from source via cmake.
Without --no-deps, pip tries to install eigenpy from PyPI, which
pulls scipy from source requiring OpenBLAS compilation that fails.

On Eigen 3.3.x (manylinux2014), EIGEN_MAKE_ALIGNED_OPERATOR_NEW defines
operator new/delete. Placed in the private section, it made destructors
of derived classes (StartSystem, MHomogeneous, User) ill-formed.
Moving to public section fixes the access error.

- Move Boost and eigenpy builds outside Python version loop (built once)
- Add set -e for fail-fast behavior
- Add -j$(nproc) for parallel compilation
- Use glob for auditwheel instead of hardcoded version string
- Drop EOL Python versions (cp38-310), keep cp311-312
- Include both /usr/local/lib and lib64 in LD_LIBRARY_PATH

b2 auto-detects Python 2.7 from the manylinux2014 container and tries
to build Boost.Python for it, which fails (missing pyconfig.h).
Write a user-config.jam and pass python=<ver> to b2 to restrict
the build to only the target Python 3.11.

PYBIN is the bin/ directory (e.g., /opt/python/cp312-cp312/bin).
PYTHON_EXECUTABLE needs the actual binary, not the directory.

- Removed unescaped ${PYBIN}/${DIR} lines that the host shell expanded
  to empty before reaching the Docker container
- Replaced hardcoded pybertini-1.0a8 filename with glob pattern
- Use full path /io/wheelhouse/ for auditwheel input
- Escape $LD_LIBRARY_PATH so it resolves inside Docker
- Clean up wheelhouse between loop iterations

- Uncomment add_subdirectory(python_bindings) in root CMakeLists.txt
  so scikit-build-core builds the _pybertini native extension
- Fix eigenpy cmake: use Python3_EXECUTABLE and Python3_NumPy_INCLUDE_DIR
  so numpy is found correctly inside the manylinux container
- Switch docker script to single quotes to avoid host shell expansion
- Build for single Python version (cp311) matching the matrix
- Remove redundant per-iteration boost/eigenpy rebuilds

Replace manual Docker manylinux script with pypa/cibuildwheel@v2.23.
CIBW_BUILD targets cp39, cp310, cp311, cp312 on manylinux_x86_64.
CIBW_BEFORE_ALL installs system deps, Boost, and eigenpy once.
CIBW_BEFORE_BUILD installs Python build deps per version.

Also fix publish steps to collect wheels from both wheelhouse/
(cibuildwheel) and dist/ (macOS/Windows) into dist/ for PyPI upload.

Same fix as core/CMakeLists.txt — Boost 1.90 (Homebrew) removed
boost_system as a library. Only request it for Boost < 1.89.
Re-find with all components to avoid overwriting Boost_LIBRARIES.

- Unified build_wheels job uses pypa/cibuildwheel@v2.23 for both
  ubuntu-latest and macos-14 with CIBW_BUILD cp39-* through cp312-*
- CIBW_SKIP *-musllinux_* to avoid unsupported builds
- CIBW_BEFORE_ALL_LINUX installs system deps, Boost, eigenpy from source
- CIBW_BEFORE_ALL_MACOS uses Homebrew for all native deps
- Separate build_windows job kept with conda + clang-cl
- Simplified artifact upload and publish step paths

python_add_library was gated behind PROJECT_IS_TOP_LEVEL but all target
configuration ran unconditionally. Now that python_bindings is included
as a subdirectory, the target must always be created.

cibuildwheel on macOS creates isolated Python environments that are
incompatible with Homebrew's boost-python3 and eigenpy (compiled
against Homebrew Python 3.14, not cibuildwheel's Python).

- Linux: cibuildwheel with cp311/cp312 (cp39/cp310 skipped by requires-python >= 3.11)
- macOS: direct build with actions/setup-python@v5 + Homebrew deps
- Windows: unchanged (conda + clang-cl)

When python_bindings is a subdirectory, ${PROJECT_NAME} resolves to the
root project 'bertini2', not 'pybertini'. The boost python linking must
target _pybertini explicitly.

Homebrew libraries on macos-14 are compiled for macOS 14.0 minimum.
delocate-wheel fails when the wheel is tagged for macOS 11.0 because
bundled dylibs have a higher minimum target than the wheel claims.

CIBW_BEFORE_ALL runs before cibuildwheel sets up any Python environment,
so the system python3 doesn't have numpy. pip3 install numpy ensures
eigenpy's cmake can detect it during configuration.

scipy is a runtime dependency, not a build dependency. Building it from
source fails on manylinux2014 due to missing OpenBLAS. Only scikit-build-core
and numpy are needed to build the wheel.

manylinux2014_i686 doesn't have eigen3-devel and the project only
targets 64-bit platforms. Skip *-manylinux_i686 alongside musllinux.

The windows_dll_manager.py existed but was never called from __init__.py.
On Windows, Python 3.8+ requires os.add_dll_directory() for DLL search.
Without it, _pybertini.pyd can't find Boost/GMP/eigenpy DLLs from conda.

Subject: [PATCH 825/944] using `SYSTEM` on external libraries, so warnings
 from THIS library

I was overwhelmed by the warnings I'm not responsible for, coming from Boost, MPFR, etc.  I cannot fix those.  But, I CAN fix the warnings from my own software.  So, by marking the external libraries as SYSTEM, the warnings don't appear.

Also, explicitly include mpfr headers, they were missing.  also, be target specific.

several tests were failing on Ubuntu (so gcc) when using compiler optimization, so relaxing the tolerances.  In particular `manual_construction_x_pow_lnum1_times_num2l` produces noise in the last 2-3 digits.  i added comments for what i got for "exact" values from vpa in Matlab.  I also note that both of the tests I modified involve `pow` for complex numbers.

+## Project Overview
+
+Bertini 2 (b2) is a C++17 numerical algebraic geometry library with Python bindings. It implements homotopy continuation for solving polynomial systems, including path tracking, endgames (power series, Cauchy), and start systems (total degree, multihomogeneous). The Python package is published to PyPI as `bertini`.
+
+## Build Commands
+
+### C++ Core Library (CMake + Ninja)
+
+```bash
+# Configure (from repo root)
+cmake -DENABLE_UNIT_TESTING=ON -G Ninja -B build -S .
+
+# Build
+cmake --build build --target all --config Release
+
+# Run all C++ tests
+ctest --test-dir build/core
+```
+
+### Python Wheel (scikit-build-core)
+
+```bash
+python3 -m build --wheel
+```
+
+The build system uses `scikit-build-core` (configured in `pyproject.toml`). The wheel build invokes CMake internally.
+
+### macOS Dependencies (Homebrew)
+
+```bash
+brew install gmp mpfr libmpc eigen@3 eigenpy boost boost-python3
+```
+
+### Linux/CI Dependencies (conda)
+
+Use `environment.yml` (Ubuntu) or `environment-win.yml` (Windows) with conda/mamba/micromamba.
+
+## Running Tests
+
+### C++ Tests (Boost.Test)
+
+Tests are defined in `core/CMakeLists.txt`. Each test suite is a separate executable:
+
+```bash
+# All tests
+ctest --test-dir build/core
+
+# Individual test executables (after build)
+./build/core/test_classes
+./build/core/test_blackbox
+./build/core/test_classic
+./build/core/test_endgames
+./build/core/test_generating
+./build/core/test_nag_algorithms
+./build/core/test_nag_datatypes
+./build/core/test_tracking_basics
+./build/core/test_settings
+```
+
+### Python Tests
+
+```bash
+pytest python/test/
+```
+
+## Architecture
+
+The project has three layers, built in order:
+
+1. **`core/`** -- C++ shared library (`libbertini2`). Header-only-heavy design under `core/include/bertini2/`. Key subsystems:
+   - `function_tree/` -- Expression tree (nodes, operators, symbols) for representing polynomial systems
+   - `system/` -- Polynomial system construction, start systems (`start/total_degree.hpp`, `start/mhom.hpp`), patches, slices
+   - `trackers/` -- Path tracking (fixed-precision and adaptive-precision trackers, predictors, Newton correctors)
+   - `endgames/` -- Power series and Cauchy endgames for singular endpoint handling
+   - `nag_algorithms/` -- Higher-level algorithms (zero-dim solve, numerical irreducible decomposition)
+   - `io/parsing/` -- Boost.Spirit Qi parsers for classic Bertini input format
+   - `blackbox/` -- CLI executable entry point (`bertini2_exe`)
+
+2. **`python_bindings/`** -- Boost.Python + eigenpy bindings producing `_pybertini` native module. Each `*_export.cpp` wraps the corresponding C++ subsystem. Depends on `eigenpy` for NumPy/Eigen interop.
+
+3. **`python/bertini/`** -- Pure Python package that wraps `_pybertini` into a user-friendly API. Submodules mirror the C++ structure: `function_tree`, `system`, `tracking`, `endgame`, `parse`, `nag_algorithm`, `multiprec`, etc.
+
+## Key Dependencies
+
+- **GMP/MPFR/MPC** -- Arbitrary-precision arithmetic (found via custom CMake modules in `cmake/`)
+- **Eigen 3.3** -- Linear algebra (pinned to v3.3)
+- **Boost** (serialization, filesystem, log, graph, regex, timer, chrono, thread, unit_test_framework, python) -- Boost >= 1.82 required; `boost_system` is conditionally linked for Boost < 1.89
+- **eigenpy** -- Eigen/NumPy bridge for Python bindings
+- **jrl-cmakemodules** -- CMake helper macros (auto-fetched via FetchContent if not found)
+
+## Build System Notes
+
+- The root `CMakeLists.txt` uses `jrl-cmakemodules` (fetched automatically). It currently only adds `core/` as a subdirectory; `python_bindings/` and `python/` subdirectory calls are commented out (the wheel build via scikit-build-core handles them).
+- `pyproject.toml` configures scikit-build-core: wheel packages from `python/bertini/`, build dir is `bld/`.
+- Cross-platform: Linux uses manylinux Docker + `auditwheel`; macOS uses Homebrew; Windows uses conda + clang-cl (MSVC has template compilation issues).
+- `-Werror` is disabled globally. `-pedantic` is stripped from flags.
+
+## CI/CD
+
+- `.github/workflows/build-and-publish-to-pypi.yml` -- Builds wheels on Ubuntu/macOS/Windows, publishes to TestPyPI on `develop` push, PyPI on version tags (`v*.*.*`).
+- Pushes to `develop` trigger TestPyPI publish; tagged releases go to PyPI with Sigstore signing and GitHub Releases.
+
+## Conventions
+
+- C++ standard: C++17. Headers use `.hpp` extension.
+- License: GPL v3 with additional terms (see `licenses/`, `core/ADDITIONAL_GPL_TERMS`).
+- Version is tracked in `python/bertini/_version.py` and `pyproject.toml`.

 The definitive resource for Bertini 1 is the book :cite:`bertinibook`.  While the way we interact with Bertini changes from version 1 to version 2, particularly when using PyBertini, the algorithms remain fundamentally the same.  So do most of the ways to change settings for the path trackers, etc.  We believe that embracing the flexibility of Python3 with PyBertini allows for much greater flexibility.  It also will relieve the user from the burden of input and output file writing and parsing.  Instead, computed results are returned directly to the user.

* Added a bunch of missing docstrings.
* Changed the rtd theme, because its sidebar better handles long strings
* removed c++ signatures, they were not helpful.
* added `:no_index:` in some places (configs) to eliminate duplicate indexing
* trimmed duplicate class/containing names for sidebar by using `toc_object_entries_show_parents = 'hide'`.
* added some custom css

Boost.Python is ABI-locked to a single CPython version. The previous
CIBW_BEFORE_ALL_LINUX built it once against the manylinux2014 system
python3 (3.9), so every wheel — cp39 through cp313 — bundled the same
libboost_python39.so. cp310/cp311/cp312/cp313 imports failed at module
init with "SystemError: initialization of _pybertini failed without
raising an exception".

Move the Boost + eigenpy build into CIBW_BEFORE_BUILD_LINUX so it runs
once per target Python against $(which python). BEFORE_ALL is reduced
to yum install + tarball downloads to /tmp.

Same ABI mismatch as the Linux fix. Homebrew's boost-python3 / eigenpy
bottles track the current Homebrew default Python (now 3.14), so a
cp313 wheel built against them ships libboost_python314.dylib and
segfaults at import in a 3.13 interpreter (Fatal Python error: SIGSEGV).

Restore the per-Python source build of Boost.Python + eigenpy that the
workflow used pre-1f3dccf6, mirroring the Linux structure: brew install
the version-independent libs (gmp/mpfr/libmpc/eigen@3) plus tarball
downloads in BEFORE_ALL_MACOS, then build Boost+eigenpy into
/tmp/deps-py per target Python in BEFORE_BUILD_MACOS.

Now that Boost.Python and eigenpy are rebuilt per target Python in
BEFORE_BUILD_MACOS, the macOS path can produce wheels for the same
Python matrix as Linux instead of just cp313. Test matrix is
collapsed back to a cross-product of {ubuntu-latest, macos-14} ×
{3.9..3.13}.

eigenpy's CMake calls find_scipy() unconditionally from
unittest/CMakeLists.txt, even with -DBUILD_TESTING=OFF, and aborts
configure with "Failed to detect scipy". The pre-1f3dccf6 workflow
installed scipy alongside numpy; restore that in BEFORE_BUILD_{LINUX,MACOS}.

scipy stopped shipping manylinux_2_17 wheels in 1.14, so the per-Python
'pip install scipy' (needed for eigenpy's find_scipy at configure time)
fell back to source-building scipy on cp310/311/312/313 inside the
manylinux2014 container and failed on missing OpenBLAS.

manylinux_2_28 (glibc 2.28, AlmaLinux 8 base) has scipy binary wheels
for cp39–cp313. Tradeoff: produced wheels require glibc 2.28+ (Ubuntu
18.04+, RHEL/CentOS 8+, Debian 10+) instead of 2.17.

a74ca563 added --no-index to the wheel install, which is the right
intent (force the local wheel) but blocks pip from reaching PyPI for
the transitive numpy dependency: "No matching distribution found for
numpy". Install numpy from PyPI first, then bertini offline from dist/.

* 📝 docs: add GitHub Pages site combining Doxygen (C++) and Sphinx (Python)

Adds a unified docs site deployed under one github.io: a small landing
page links to the existing Sphinx site at /python/ and a new Doxygen
reference for the C++ core at /cpp/. Sphinx imports `bertini` from PyPI
to keep CI fast; C++ docs use doxygen-awesome-css for a modern theme.
Triggered on pushes to develop and version tags.

* 📚 docs: update push branch in workflow to 'docs'

* 📚 docs: update push branch in workflow from 'docs' to 'develop'

* 🐛 docs(ci): create Doxygen output directory before build

Doxygen only auto-creates a single directory level. The nested
`build/docs/cpp` path needs `mkdir -p` first to avoid the
"Output directory ... does not exist and cannot be created" error.

* 🐛 docs(ci): only deploy to GitHub Pages from develop or tags

The github-pages environment's branch-protection rule rejects
deployments from non-default branches, so PR runs were failing at
the deploy step despite a successful build. Gate the deploy job on
the ref so PRs build for validation but don't attempt to publish.

* 📚 docs: update workflow to trigger on 'docs' branch instead of 'develop'

* 📚 docs: update workflow condition to trigger on 'docs' branch

* 📝 docs: surface git commit hash and build date across the docs

Compute the commit SHA and build date once in CI and inject into all
three doc surfaces so users can identify which revision a deployed
docs page reflects:
- Doxygen: PROJECT_NUMBER override via stdin (no Doxyfile changes)
- Sphinx: env vars BERTINI_GIT_SHA / BERTINI_BUILD_DATE override the
  existing gitpython lookup; appended to `release` so the sidebar
  shows `<sha7> (YYYY-MM-DD HH:MM UTC)`
- Landing page: footer line links the short SHA to the GitHub commit

Also switches the checkout to fetch-depth: 0 so gitpython works for
local builds too.

* 🐛 docs(sphinx): only inject local source paths if they have _pybertini.so

Sphinx autodoc was producing empty stubs for every Python class and
function on the deployed site. Root cause: conf.py unconditionally
inserted the repo's `python/` source tree at the front of sys.path,
which shadowed the pip-installed `bertini` package in CI. The source
tree's `__init__.py` re-exports from `bertini._pybertini`, but the
compiled `.so` only exists next to the installed package -- so
`import bertini._pybertini` fell over and autodoc swallowed the error.

Now we only prepend the source tree (or `bld/python_bindings`) if the
binary extension actually lives there. CI's pip-installed package is
no longer shadowed; local builds with `BERTINI_BUILD_DIR=/path/to/bld`
or a populated source tree still work.

Verified locally: detailed/multiprec.html went from a near-empty shell
to a 556-line page with full autodoc'd class signatures.

* 📝 docs(sphinx): show git commit info in PyBertini doc footer

Override sphinx_rtd_theme's footer.html via the `extrafooter` block so
every Python docs page shows "Built from <short-sha> on <date>" with
a link to the GitHub commit. Values come from the html_context dict
populated by the same env vars CI already sets.

Adds matching styling to _static/custom.css. Falls back to no-op when
env vars aren't set (local builds without git metadata).

* 📚 docs: update GitHub repository links and workflow conditions

* 🔧 chore: update publish conditions for TestPyPI and PyPI in workflow

* ♻️ refactor(docs): enhance concurrency group naming for deployments

notably, this caused some example code (also committed in this PR) to not freeze caught in this process, but instead crash.  i'd rather have crashes than freezes.

also notably, the denominator in `StepsizeSatisfyingCriterionB` changed from `predictor_order+1` to `predictor_order+1.0` -- this was probably a source of integer arithmetic problems, and now we guarantee that it's not integer arithmetic down there

⚡ 👷  make the workflow parallel

Extend the GitHub Actions build matrix to include Python 3.9–3.13 and make cibuildwheel runs Python-version aware. Add version-specific cache keys and include temporary Boost/eigenpy tarballs in the cache. Set CIBW_BUILD per matrix.python-version (cpXY) via a step that writes to GITHUB_ENV, and use that env value in the pypa/cibuildwheel action. Update artifact upload/download names to include the Python version so wheels are stored and retrieved per-Python build.

👷 merge doc generation into the workflow

so the docs always use the current version

👷 factor out building of boost for faster CI builds

👷 remove unnecessary deps for building docs

hopefully lets docs build much faster

👷 better caching for ubuntu

by using the github workspace.

🚧 debugging cache missing during workflow

by printing

👷 another attempt to get cacheing to work

👷 restrict to linux

👷 bug fixing small error w container

a trivial commit, to trigger a build on github action

👷 working towards cache correctness on macos

👷 publish to testpypi / real pypi conditionally

and the dispatch is controlled by the version, set in the pyproject.toml file.  if there's a `.dev#`  in the version number, then it will go to test.  otherwise, if on main, and it's a semver, then it goes to real pypi.

🚧 more debugging cuz cache not working on macos

🚧 separate debug step

👷 yet another attempt to get caching of boost/deps

🙈 ignore dist folder

⚰️ delete old dead pyproject.toml file

👷 remove caching

it was a failure. but at least i got parallel jobs working for macos and linux.  plus other important fixes along the way

👷 remove dupe scipy, add missing pytest options

🚧 debugging test running on windows

👷 getting away from the proprietary channels

force version of python for windows

👷 ✨ add ability to re-use wheels on manually triggered run

here's how to trigger a reuse run:

1. Go to your repo on GitHub
2. Click Actions in the top nav
3. Click your workflow name in the left sidebar ("Build, publish, and document Python 🐍 distribution 📦")
4. Click the Run workflow button (top right of the runs list)
5. A dropdown appears — paste the run ID from your previous successful build into the "Run ID to reuse wheels from" field
6. Click Run workflow

To find the run ID from a previous run, click on that run and look at the URL:
https://github.com/yourorg/b2/actions/runs/14926731284
                                                ↑
                                          this number
So for example you'd paste 14926731284 into the input field.
One thing to be aware of: artifacts expire after 90 days by default, and on some GitHub plans they expire sooner. If you try to reuse a run that's too old, the download step will fail. But for day-to-day iteration on tests this won't be an issue.

👷 improved names

👷 Make sure pytest is the one from THIS python, not default

Praying this fixes running on Windows.

date bump to trigger a run

so much learning to do...

👷 fixing paths for pip etc in windows

combine some steps.

🚧 yet another attempt to fix paths. also, update versions.

yes, i'm mixing concerns.

🚧 fixed erroneous appl of conda run.  hopefully correct `delvewheel` in powershell

maddening, this is.

😢

fixed messed up line

yet another attempt

added strict to build step

👷 split workflows to help reason

publish depends on build and test.  factored out some checks.

i hope this helps keep the workflow understandable and maintainable

👷 action bump.  added pip to env

👷 added option to not build python part

👷 added macos-13, so i get intel mac wheels

👷 action bumps

🚧 👷 trying to get c++ testing in the mix

and also trying to get boost re-used between things.

🚧 better caching of boost?

👷 correct os's for mac

reduce number of processors on linux.  fix boost path

cuz it was toooo much

copy around the cmake files

one more attempt to get caching to work and then i give up

🚧 un-did the factoring out of boost.

i will simply accept that Claude is incapable of doing this, and i don't want to learn how to do it right.  i do hope this works.

make runners conditional on branch

👷 disable documentation building when testing

and back to macos 15.  i'm leaving it there, runner avail be damned

👷 added an env var to help c++ testing in unix

cap parallel for building tests to 2. back to macos-14

because macos-14 is compatible with later.  i think the only reason to later go to 15 is because i have to, due to a deprecation or force.  but that's later, not now.  committing and praying.  the jobs take a long time...  the last one was 1 hr 45 minutes in total.  so it's really expensive to run these all.

add library path for macos

again reducing level of parallelism

due to liekly OOM while building on runner

yet more reduction in parallel

let python versions be different on branches and tags

allow manual triggering of full matrix workflow

and also building boost full parallel is back.  sorry for the vacillation on that.

Boost.Multiprecision >= 1.87 reads thread_default_precision when
default-constructing mpfr_float/mpfr_complex temporaries, including
those created by boost::python const& argument extractors. Left at 0,
mpfr_init2 aborts the process.

Two-part fix:
- DefaultPrecision(unsigned) now propagates to thread_default_precision
  for both mpfr_float and mpfr_complex. (Re-applies commit 3111255b,
  which was reverted in 295d0827 without stated reason.)
- mpfr_export ExposeFreeNumFns() seeds thread_default_precision on
  the interpreter thread at module load, covering tests whose setUp
  does not call default_precision (e.g. SystemTest.test_add_systems).

Surfaces as a Fatal Python error: Aborted on macos-15-intel inside
System.eval, where boost::python instantiates Vec<mpfr> temporaries
during numpy->Eigen conversion.

Adds five C++ regression tests for the precision contract that the
macos-15-intel SIGABRT exposed:

complex_test.cpp:
- default_precision_aligns_thread_local_with_static: after
  bertini::DefaultPrecision(N), both mpfr_float and mpfr_complex
  report N for default_precision() and thread_default_precision().
- default_constructed_{mpfr_float,mpfr_complex}_inherits_default_precision:
  default-constructed values pick up the current default, not 0.
- default_precision_recovers_thread_local_from_zero: direct regression
  test for the fix — explicitly set thread_default to 0 (the state of
  a freshly-spawned thread on Boost 1.87+), call DefaultPrecision(50),
  verify thread_default is now 50 and default-constructed temporaries
  use that precision rather than aborting in mpfr_init2.

system_test.cpp:
- add_two_systems_evaluated_in_mpfr: C++ mirror of the Python
  test_add_systems, exercising Vec<mpfr> evaluation through System +=
  System. The existing add_two_systems only covered Vec<dbl>, which
  is why the C++ suite never caught the Boost-1.87 regression.

Six new C++ tests against System operator semantics. Three pass cleanly;
two are marked utf::expected_failures because they expose a real bug that
warrants a follow-up fix.

Passing:
- eval_wrong_size_input_throws: System::Eval throws runtime_error on
  variable vectors of the wrong size (both too small and too big).
- add_systems_chain: a += b += c accumulates as (a+b+c, b+c), exercising
  operator+= return-by-reference and the right-associative grouping.
- add_incompatible_systems_throws: operator+= throws on mismatched
  function counts, variable counts, and variable-group counts.
- add_system_to_self_doubles_under_function_tree_eval: with
  EvalMethod::FunctionTree, sys += sys correctly doubles every function.

Bug surfaced (expected_failures):
- operator_plus_equals_invalidates_slp_cache (expected_failures(2))
- operator_mult_equals_invalidates_slp_cache (expected_failures(1))

Both operator+= and operator*= mutate Function::entry_node_ via SetRoot
but leave is_differentiated_ true, so the cached StraightLineProgram
(the default eval method) keeps the pre-mutation representation. Any
Eval performed before the mutation primes that cache; subsequent Evals
return stale values. The existing add_two_systems test passes only
because it never Evals before the mutation — the SLP is built fresh
from the post-mutation trees on the first (and only) Eval.

Drop the expected_failures decorators once operator+= and operator*=
set is_differentiated_ = false (and invalidate any other dependent
cached state) before returning.

Both operators mutate Function::entry_node_ via SetRoot but previously
left is_differentiated_ unchanged. The default eval method
(EvalMethod::SLP) caches a StraightLineProgram built lazily on first
Differentiate(); without invalidation, any Eval performed before the
mutation primes that cache and subsequent Evals read stale values.

Match the canonical invalidation pattern used by AddFunction,
AddVariableGroup, etc.: setting is_differentiated_ = false triggers
Differentiate() on the next access, which rebuilds the SLP along with
jacobian_, space_derivatives_, and time_derivatives_.

Tests previously marked utf::expected_failures now pass without the
decorator, so the decorators are removed.

Audit of System mutators surfaced four more public methods with the same
stale-SLP / stale-derivatives pattern as operator+= and operator*=:

- ReorderFunctionsByDegreeDecreasing / ReorderFunctionsByDegreeIncreasing
  swap entries in functions_; without invalidation, the SLP keeps the old
  index → function mapping, and jacobian_ entries become misaligned with
  the new function order.
- SimplifyFunctions rewrites each function tree via Simplify(); without
  invalidation, the SLP retains the un-simplified structure (a
  performance leak, not a correctness one, since Simplify preserves math).
- ClearVariables wipes variable groups; without invalidation the SLP
  refers to vanished variables and the cached variable ordering is stale.

All four follow the canonical pattern used by AddFunction, Homogenize,
etc.: set is_differentiated_ = false (and have_ordering_ = false where
variables are also affected).

New tests:
- reorder_functions_decreasing_invalidates_slp_cache
- reorder_functions_increasing_invalidates_slp_cache
Both Eval before and after the reorder to verify the SLP follows the new
ordering. SimplifyFunctions and ClearVariables are not directly testable
through Eval (math-preserving / mask-by-downstream-AddVariableGroup) so
no test is added for those — the fixes are by analogy to the established
pattern.

Two-part fix for the macos-15-intel SIGABRT in System.eval:

1. mpfr_export.cpp ExposeFreeNumFns():
   Replace `DefaultPrecision(DefaultPrecision())` with a direct read of
   the static default. On Boost 1.87 the getter may delegate to the
   thread-local (which is 0), causing DefaultPrecision(0) -> mpfr abort.
   Now: read mpfr_float::default_precision() directly, fall back to 50
   (Boost's library default) if 0, and set thread_default_precision
   unconditionally.

2. system_export.cpp eval overload registration order:
   Register mpfr overloads before dbl so boost::python tries dbl first
   (LIFO resolution). A numpy int64 array previously caused eigenpy to
   probe Vec<mpfr> construction first; with thread_default_precision=0
   on Boost>=1.87 that aborts before we even reach the dbl path.
   Explicitly passing Vec<mpfr_complex> still resolves to the mpfr
   overload — only ambiguous/numeric inputs are affected.

1.87 lets thread_default_precision() return 0 on fresh threads and passes
it straight to mpfr_init2 with no guard → SIGABRT. 1.90 pre-seeds thread-
local precision from the global default and also guards against 0, matching
the Homebrew version used in local development.

Previously the full matrix (macos-15-intel, all Python versions) only ran
on pushes to main/develop and tags — too late to catch issues before merge.
PRs targeting develop now get the full matrix so every platform is verified
before the merge happens.

SLPCompiler::Compile() grows the mpfr_complex memory block via
std::vector::resize(), which default-constructs each new slot via
mpfr_init2(x, thread_default_precision()). On Boost 1.87+ that
thread-local value can be 0 on fresh threads, causing mpfr_init2 to
abort with SIGABRT.

Call DefaultPrecision(slp.precision_) just before the resize so both
the static and thread-local defaults match the SLP's own precision.
This makes the memory growth independent of whatever the thread default
happened to be.

This path is now hit by test_add_systems on macos-15-intel after the
operator+= fix started invalidating is_differentiated_, which causes
s1.eval() to trigger Differentiate() -> SLPCompiler::Compile().

An MPFR/Boost interaction causes a SIGABRT in pytest on macos-15-intel
that we cannot reproduce locally. Pausing Intel macOS support pending
a reproducer or an upstream fix. The release notes should call this
out so users on Intel Macs know the wheels are not built or tested
for that platform right now.

The fast_matrix branch was already Intel-free; only the full_matrix
branch needed editing. Re-add "macos-15-intel" to that branch's `os`
list when ready to revisit.

Summarize the work that has accumulated on pr/212 since 1.0.3: PyPI
wheels across Linux / macOS-arm / Windows for py3.9-3.13, the package
rename to bertini2, scikit-build-core packaging, version unification
via pyproject.toml, the GitHub Pages docs site, Boost 1.87->1.90 bump,
this session's precision-handling fixes in System / SLP, and the
removal of macos-15-intel from the supported matrix.

Also rename the changelog header from "bertini" to "bertini2" to match
the PyPI package name.

+## [2.0.1] - 2026-05-16
+
+First release under the `bertini2` PyPI name. This is the consolidation of
+several months of cross-platform packaging work, dependency-compatibility
+fixes, documentation, and a final round of precision-handling fixes in the
+system / SLP path. Intel macOS is dropped from the supported platform list
+for this release (see Removed below).
+
+### Added
+
+- Wheel distributions on PyPI for Linux, macOS (Apple Silicon), and Windows
+  across Python 3.9 – 3.13. Linux wheels use the `manylinux_2_28` image; macOS
+  and Linux wheels are produced via `cibuildwheel`; Windows wheels bundle
+  required DLLs via `delvewheel` and a `windows_dll_manager.py` helper that
+  registers DLL search paths before importing `_pybertini`.
+- GitHub Pages documentation site: C++ API via Doxygen, Python API via Sphinx.
+- Version numbers (b2, GMP, MPFR, Eigen, Boost) exposed from the Python
+  package so users can query them at runtime.
+- `CHANGELOG.md` itself, following the *Keep a Changelog* format.
+
+### Changed
+
+- **Package renamed: `pybertini` → `bertini` → `bertini2`.** The current PyPI
+  name is `bertini2`. Update your `pip install` and import statements
+  accordingly; the Python module still imports as `import bertini`.
+- Version is now read from `pyproject.toml` by CMake, removing the two-place
+  manual sync that previously drifted.
+- Build system: `scikit-build-core` configures CMake for the wheel build;
+  `pyproject.toml` is the single source of truth for build inputs. The Linux
+  wheel build rebuilds Boost.Python and eigenpy per target Python version so
+  each wheel ships a matching `libboost_python3X`.
+- CI matrix expanded to cover Ubuntu, macOS (Apple Silicon), and Windows for
+  Python 3.9 – 3.13. PRs targeting `develop` and pushes to `develop` / `main`
+  run the full matrix; other branches run a fast Ubuntu + macos-14 + Python
+  3.11 matrix.
+- CI build now uses Boost 1.90 (was 1.87). Boost 1.90 pre-seeds
+  `thread_default_precision` from the global default and guards against 0,
+  removing a class of MPFR abort hazards.
+- `boost_system` is now conditionally linked for Boost < 1.89 only (Boost 1.89
+  dropped the separate library).
+- Eigen requirement updated to `3.3...3.4` with the macOS install switched to
+  Homebrew's `eigen@3` formula.
+- Tests across platforms now use a unified precision-handling pattern,
+  eliminating per-platform skips and conditional precision rituals.
+- `MACOSX_DEPLOYMENT_TARGET` co-varies with the runner version so wheels
+  produced on macos-14 are loadable on the same OS family.
+- TestPyPI publishes on every push to `develop`; PyPI publishes on tagged
+  releases (`v*.*.*`) with Sigstore signing and a GitHub Release.
+
+### Fixed
+
+- `System::operator+=` and `System::operator*=` now invalidate the cached
+  derivatives flag (`is_differentiated_`), so a subsequent `eval` rebuilds the
+  SLP instead of evaluating against stale derivatives. The companion mutators
+  `Reorder`, `Simplify`, and `ClearVariables` also invalidate the cache.
+- `SLPCompiler::Compile` now seeds the mpfr default precision from the SLP's
+  own `precision_` immediately before growing the `mpfr_complex` memory block.
+  This prevents a `mpfr_init2(x, 0)` abort when `thread_default_precision()`
+  is left at 0 on a fresh thread under Boost ≥ 1.87.
+- Python module init seeds `thread_default_precision` so the first MPFR
+  construction on the interpreter thread is always valid.
+- `eval` overload registration order in the Python bindings changed so the
+  double-precision overload is tried before the multi-precision overload for
+  ambiguous inputs (e.g. NumPy int64 arrays); this avoids the eigenpy
+  `Vec<mpfr>` extractor probing MPFR construction with precision 0.
+- `EIGEN_MAKE_ALIGNED_OPERATOR_NEW` moved to the `public` section of the
+  `System` class (was incorrectly placed in a non-public section).
+- A second `find_package(Boost)` no longer clobbers `Boost_LIBRARIES`.
+- The `_pybertini` target is always created (previously it was only created
+  when bertini was the top-level CMake project, breaking out-of-tree builds).
+- Various MSVC-specific build fixes: `/bigobj`, `/EHsc`, explicit-type
+  workarounds for template instantiation issues, Release-config library
+  linking.
+
+### Removed
+
+- **Intel macOS (`macos-15-intel`) is not built or tested in this release.**
+  A SIGABRT in pytest involving MPFR/Boost surfaces only on Intel runners and
+  cannot be reproduced on the maintainer's development hardware. Intel wheels
+  will return once a reproducer or upstream fix is in hand. Users on Intel
+  Macs should pin to a 1.0.x release or build from source.
+- Stale build artifacts and outdated Python-binding documentation removed
+  from the repo.
+

 # Overview
