  jmetal.core.Operator
      jmetal.operators.crossover.Crossover
          jmetal.operators.crossover.PMXCrossover

All Implemented Interfaces:

java.io.Serializable

public class PMXCrossover
extends Crossover

This class allows to apply a PMX crossover operator using two parent solutions. NOTE: the operator is applied to the first encodings.variable of the solutions, and the type of those variables must be VariableType_.Permutation.
