12:54 Changeset [10076] by ascheibe

#2110 updated list of problems and algorithms

11:29 Changeset [10075] by sawinkle


  • For each newly created node, ResetLocalParameters() has to be called, if possible. Otherwise 'Variable' symbols won't be initialized correctly. (E.g. internal ValueName is null and causes exceptions.)
  • Method MapDepthFirstRecursively() of DepthFirstMapper.cs checks subtree boundaries by using the MinimumArity instead of the MaximumArity. Otherwise e.g. adding the 'Addition' symbol will cause very short trees, because this symbol has got a MaximumArity of 255! This would cause, that the tree is immediately full, after insertion of one 'Addition' symbol, if the genotype length is e.g. just 100.
  • Several bug fixes.
  • Unresolved issues:
    • Changes in the selected grammar are not taken into account during a run (e.g. 'Addition' symbols will be inserted into the tree, although its checkbox was unchecked previously).
    • Exception, if a division by zero is tried.
    • Wrapping mechanism.

#2026: finished tree searcher for artifical ant, multiplexer and even parity examples. (+ performance tweak in Artificial Ant.txt)

20:18 Changeset [10073] by sawinkle


  • Renamed all identifiers within the files to include 'GE', where necessary.
  • Changed the namespaces of all files to 'HeuristicLab.Problems.GrammaticalEvolution'.
  • Added the parameters IntegerVector, GenotypeToPhenotype and SymbolicExpressionTreeGrammar to the Evaluator classes, where necessary.
  • Changed the SolutionCreator from ISymbolicDataAnalysisSolutionCreator to IIntegerVectorCreator; changed the Evaluator from ISymbolicDataAnalysisEvaluator<T> to IGESymbolicDataAnalysisEvaluator<T>; the problem data class/interface IDataAnalysisProblemData stays the same.
  • The methods Evaluate() and Calculate() of the specific Evaluators won't change -> the genotype-to-phenotype mapping process is done within the Apply() method.
19:52 Changeset [10072] by sawinkle

#2109: added copies of files of the SymbolicAnalysis projects and the SymbolicRegression projects and renamed them to include 'GE'

#2109: resolved switch error

19:21 Changeset [10069] by sawinkle

#2109: an error occurred, when trying to switch GEArtificialAntEvaluator.cs to the sub folder ArtificialAnt; GEArtificialAntEvaluator.cs was switched as folder (!) to branches\GrammaticalEvolution\HeuristicLab.Problems.GrammaticalEvolution

18:44 Changeset [10068] by sawinkle


  • Removed the parameters MaxFunctionDefinitions and MaxFunctionArguments from GEArtificialAntProblem.cs, because automatically defined functions (adf) won't be supported by the Grammatical Evolution implementation of the Artificial Ant problem.
  • Switched from SharpDevelop to Visual Studio 2012 and installed 'Productivity Power Tools 2012'. This extension includes the options 'Format Document on save' and 'Remove and Sort Usings on save', so that some usings were deleted, sorted and the formating changed slightly. Furthermore 'Visual Studio 2010 text editor settings.vssettings' were included.
  • Added new folders ArtificialAnt and Symbolic to separate the files for the ArtificialAnt problem and the Symbolic Regression problem (single objective).
