Last change on this file since 14547 was 13404, checked in by abeham, 9 years ago

#2521:

  • Adapted Knapsack problem to new problem infrastructure
  • Introduced additional interfaces in binary vector encoding
  • Improved KnapsackImprovementOperator which requires less evaluated solutions in case of an infeasible start solution

Loosely related change:

  • All LookupParameters are now shown by default
  • Wiring code should make sure that wired parameters are hidden
