Message:

#2521:

• Adapted single-objective test function problem to new problem infrastructure
• Added additional interfaces to RealVectorEncoding
• Fixed IParticleUpdater interface (must implement IStochasticOperator if it contains a Random parameter)

Location:

Files:

• . (moved) (moved from branches/ProblemRefactoring/HeuristicLab.Problems.TestFunctions/3.3/Evaluators)
• Multinormal.cs (copied) (copied from branches/ProblemRefactoring/HeuristicLab.Problems.TestFunctions/3.3/Evaluators/MultinormalEvaluator.cs) (4 diffs)
