Changeset 5352 for trunk/sources/HeuristicLab.Algorithms.GeneticAlgorithm

Timestamp:

01/21/11 22:51:59 (14 years ago)

Author:

Message:

#1333

• Removed changes to IntCounter that would make it thread-safe, if a thread-safe operator is needed a separate one should be implemented
• Moved counting of evaluated solutions out of the parallel region

Location:

trunk/sources/HeuristicLab.Algorithms.GeneticAlgorithm/3.3

Files:

• GeneticAlgorithm.cs (modified) (3 diffs)
• GeneticAlgorithmMainLoop.cs (modified) (5 diffs)
