Changeset 17695 for branches/2521_ProblemRefactoring/HeuristicLab.Problems.DataAnalysis.Symbolic.Classification/3.4/SingleObjective/SymbolicClassificationSingleObjectiveProblem.cs

Message:

#2521:

• Moving solution creator parameter from problems to algorithms (breaking wiring in some HeuristicOptimizationProblems)
• Disallowing evaluator or encoding changes in encoding-specific base problems (to avoid confusion in derived problems whether this needs to be handled or not)
• Added private set to ReferenceParameter property (serialization)
