Changeset 2843 for trunk/sources/HeuristicLab.GP.StructureIdentification/3.3/FunctionLibraryInjectors/SimpleFunctionLibraryInjector.cs

Timestamp:

Message:

Removed max. and min. time offset constraints as algorithm parameters and from all engines. The time constraints were added to the relevant terminal symbols (variable & differential) instead. The time offset constraint can be changed by editing the symbols in the function library. #880 (Max and min time offsets for variable symbols are not set correctly by FunctionLibraryInjectors)
