#2174: Worked on programmable problem

  • Changed ProblemBase to IProblemDefinition and SingleObjectiveProblemBase to ISingleObjectiveProblemDefinition
  • Derived ParameterVectorCreater, -Crossover, and -Manipulator from MultiOperator<> instead of InstrumentedOperator
  • Split the megamoth ScriptOnInstanceChanged to multiple methods dealing with single-vector and multi-vector encodings separately, it's still a lot of tedious code

  • General support for multi-vector encoding

11:36 Changeset [10843] by rstoll
  • Fixed or combination filter, default value was set to true and thus all rows where filtered (regardless of the actual filter)
