Solver description

The following components are representation-dependent:

  • eoRealVectorBounds: Solution encoding
  • eoRealInitBounded: The initializer
  • WFGXEval (X is the number of the problem (1 to 9): Evaluator containing the objective function
  • SBXCrossover: crossover
  • PolynomialMutation: mutation

The three algorithms used:

  • WFG_IBEA
  • WFG_NSGAII
  • WFG_SPEA2
