#1980:

  • fixed several bugs (crossover, subsumption, serialization etc.)
  • added ModuloOperator
  • CombinedIntegerVectorClassificationProblem\Data and VariableVectorClassificationProblem\Data inherit from ConditionActionClassificationProblem\Data
  • it can now be set how often the analyzers have to be executed
  • VariableVectorAction, VariableVectorCondition and VariableVectorInput now inherit from Item
