Last change on this file since 10276 was 10068, checked in by sawinkle, 9 years ago

#2109:

  • 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).
