Enable speed optimisation for a fixed route#195
Merged
Conversation
Raise ValueErrors for pure speed optimisation if initial population is not read via geojson and more than one file is provided.
…ation Every individual of the initial population gets a different, constant velocity. The velocity values are determined as quantiles from a gaussian distribution centered around the user-defined boat speed. A unit test is added, accordingly.
Implement crossover function that replaces the speed of a random sequence of waypoints of one individual by the average speed of a random sequence of another individual. Replace SpeedCrossover by TwoPointCrossoverSpeed as default crossover for speed optimisation.
Adjust parameters n_updates and sigma to reduce strong speed fluctuations in output routes. Add smoothening function to allow only speed differences of consecutive waypoints up to a certain limit.
Add tests for: TwoPointCrossoverSpeed, utils.smoothen_speed, utils.check_speed_diff
