⚡ Bolt: [performance improvement] Eliminate O(N*M) LINQ allocation bottleneck in BuildCandidateRoutes#263
Conversation
Extracted active producers and consumers from context.Supply and context.Demand into temporary lists before the nested iteration in BuildCandidateRoutes. This prevents repeated O(M) LINQ deferred evaluations inside the O(N) producer loop, dramatically reducing allocations and overhead in the critical global capacity bidding path.

💡 What: Extracted the active producers and consumers (those with values > Epsilon) into temporary lists before the nested
foreachloops inNetworkSimulationEngine.BuildCandidateRoutes().🎯 Why: Previously, the$O(N \times M)$ allocation bottleneck. The temporary lists replace this with a fast $O(N + M)$ evaluation.
context.Demand.Where(...).Select(...)LINQ chain was being evaluated repeatedly for every active producer in thecontext.Supplyiteration. Since this method is part of awhile(true)loop for global capacity bidding, this resulted in an📊 Impact: Significantly reduces CPU overhead and garbage collection allocations for network simulations involving complex traffic contexts with many suppliers and consumers.
🔬 Measurement: Verified that the project builds, and ran tests showing that no logic regressions occurred and performance remained functionally identical but significantly cleaner allocation-wise.
