SymReg functionality to remove for HeuristicLab 4.0

[gkronber]

HeuristicLab provides several features for Genetic Programming / Symbolic Regression that are either not implemented very well, seldomly used, or unsupported. In this ticket we collect which things should be removed for HeuristicLab 4.0

Definitely remove:

• Automatically defined functions (ADF), ArchitectureAlteringOperators
• Integral and derivative symbol
• ILEmitting interpreter
• ExpressionCompiled interpreter

Candidates:

• VariableCondition symbol
• Special functions (airy, erf, erfc, ...)
• GrammarEnumeration
• Formatters: Smalltalk, ...
• Tree grammars
• TimeSeries & Symbols
• Evaluators: LogResiduals, ....
• LM-BFGS as HL algorithm
• Combination of covariance functions for Gaussian processes
• tSNE
• ResponseFunctionView, 'GradientView'
• SymbolicTrading
• GPR covariance optimization problem
• GBM (alternativ: für alle regression algs öffnen)
• Robocode
• NN, NN ensemble (alglib)
• Interpreter: check solution with interval arithmetic (can be accomplished via shape-constrained SymReg)
• SymRegProblem: Apply linear scaling (do it via grammar)
• Transformations (for features)
• Pearson R² evaluator
• Power symbol
• BinaryFactorVariable symbol
• Robocode problem
• OverfittingAnalyzer
• ResidualsLineChart
• ResidualsHistogram
