Class DifferentialEvolutionCrossover

java.lang.Object
  jmetal.core.Operator
      jmetal.operators.crossover.Crossover
          jmetal.operators.crossover.DifferentialEvolutionCrossover

All Implemented Interfaces:

java.io.Serializable

public class DifferentialEvolutionCrossover
extends Crossover

Differential evolution crossover operators Comments: - The operator receives two parameters: the current individual and an array of three parent individuals - The best and rand variants depends on the third parent, according whether it represents the current of the "best" individual or a randon one. The implementation of both variants are the same, due to that the parent selection is external to the crossover operator. - Implemented variants: - rand/1/bin (best/1/bin) - rand/1/exp (best/1/exp) - current-to-rand/1 (current-to-best/1) - current-to-rand/1/bin (current-to-best/1/bin) - current-to-rand/1/exp (current-to-best/1/exp)
