I have looked over the changes and have some minor comments:

  • I think in the IntegerVectorCreator the AfterDeserialization method should throw an exception if min and max are null (though this will probably be never the case?)
  • The documentation comments for the Apply method in UniformRandomIntegerVectorCreator should be updated.
  • StdDevStrategyVectorCrossover.cs as well as StdDevStrategyVectorCreator.cs are in the Manipulators source folder. Shouldn't they be located in the Creators and Crossovers folders?
  • Round/Floor/CeilingFeasible is contained in the Crossover and the Manipulator base classes. Maybe we should move them to an own source file so that the code doesn't get duplicated.
  • BoundedIntegerVectorManipulator: The exception thrown by the Manipulate method says UniformSomePositionsManipulator.

Thank you for the review and the comments!

r8184:8185

  • Updated documentation and error messages
  • Added an extra base class to unify the implementation of the round methods
  • Moved strategy parameter vectors to separate folder (as in RealVectorEncoding)

Regarding the other comment:

  • Throwing an exception in IntegerVectorCreator.AfterDeserialization would break backwards compatibility. Because they're ValueLookupParameters it is feasible to assume that their value can be null.

If you have no further comments, please set the ticket as readytorelease.
