[gkronber]

TODO:

• ShapeConstraintsView shows warning about "Unparsed changes" when opening the view
• Label about "Unparsed changes" is moved behind parse button when the view is not wide enough
• Exception wenn "OptimizeParameters = false" in NMSE Evaluator with constraints
• Maximization array in MultiObjectiveEvaluator should use the Maximization flag from problem instead
• Maximization should be automatically updated when constraints are changed (added, removed, enabled, disabled)
• rounding for constraint violation values in multi-objective evaluator
• line spaces in help for shape constraints (.rtf file)
• Data Preprocessing View cannot be opened
• It seems the variable intervals are lost when solutions are combined to an ensemble (use Cross-validation to test this)
• Add a new class ShapeConstrainedRegressionProblemData derived from RegressionProblemData
• Prepare a sample for shape-constrained symbolic regression with GP
