Shape Constraint Transformations

[dpiringe]

Implementing user defined transformations on symbolic expression trees whereby every transformation has a set of shape constraints.

• merged trunk into branch

r18181

• added the class ExtendedConstraint which represents an expression (the transformation of the found model) and the corresponding shape constraints
• added a list of ExtendedConstraint in NMSESingleObjectiveConstraintsEvaluator to make future tests/experiments (exists only temporarily in NMSESingleObjectiveConstraintsEvaluator, will be moved later)

r18213

• reimplemented extended constraints with an interface and an implementation, because of project reference troubles
• moved the extended shape constraints into IShapeConstrainedRegressionProblemData
• added thresholds for shape constraints -> the error is linear between 0 and 1, error caps at 1 when error >= (intervalbound + thresholdbound)
  • adapted ShapeConstraint and ShapeConstraintsParser to identify and store thresholds
• adapted IntervalUtil to work with thresholds
• adapted NMSESingleObjectiveConstraintsEvaluator and ShapeConstraintsAnalyzer to work with extended constraints
• added a new chart in ShapeConstraintsAnalyzer to show the average constraint violation

• fixed a bug with NaN values for constraint validations
• added a result collection for all shape constraint violations in SymbolicRegressionSolution
