Message:

#1772: Micro optimization inside the TraceCalculator and inside the GenealogyGraphNode (Children and Parents properties), resulting in maybe 25% speed gain. Corrected item name for the BeforeCrossoverOperator, very minor refactoring inside the BeforeManipulatorOperator. Updated project file.

File:

• branches/HeuristicLab.EvolutionTracking/HeuristicLab.Problems.DataAnalysis.Symbolic/3.4/Tracking/TraceCalculator.cs (modified) (7 diffs)
