Message:

#2269

• Removed AgeInheritance enum and used a double [0-1] instead.
• Added a WeightingReducer that uses the new double-weight for weighting between the lower and higher value.

Location:

branches/ALPS/HeuristicLab.Algorithms.ALPS/3.3

Files:

• AgeInheritance.cs (deleted)
• AlpsGeneticAlgorithm.cs (modified) (9 diffs)
• AlpsGeneticAlgorithmMainLoop.cs (modified) (2 diffs)
• HeuristicLab.Algorithms.ALPS-3.3.csproj (modified) (1 diff)
• WeightingReducer.cs (added)
