Last change on this file since 13396 was 13396, checked in by abeham, 4 years ago

#2521:

  • Refactored QuadraticAssignmentProblem to use new SingleObjectiveProblem
    • Removed QAPEvaluator
    • Adapted RobustTabooSearch
  • Introduced several interfaces in PermutationEncoding necessary for wiring
  • Changed all Encodings to use IItem instead of IOperator in ConfigureOperators (name still unchanged)
  • Added a protected MaximizationParameter property in SingleObjectiveProblem (necessary for wiring)
  • Changed AlleleFrequnencyAnalyzer to use ISolution interface instead of IItem
  • Added a comment to ISolutionCreator<TSolution> of some changes that would be welcomed
