Message:

#2697:

• renaming of folder "Transformation" to "Converters" to distinguish between transformations for variables (from data preprocessing) and classes for transformation of trees.
• renamed SymbolicDataAnalysisExpressionTreeSimplifier -> TreeSimplifier
• Implemented a converter to create a linar model as a symbolic expression tree

File:

• trunk/sources/HeuristicLab.Problems.DataAnalysis.Symbolic.Regression/3.4/SingleObjective/Evaluators/SymbolicRegressionConstantOptimizationEvaluator.cs (modified) (4 diffs)
