Package org.uma.jmetal.operator.crossover.impl

Class HUXCrossover<S extends BinarySolution>

java.lang.Object

org.uma.jmetal.operator.crossover.impl.HUXCrossover<S>

All Implemented Interfaces:

Serializable, CrossoverOperator<S>, Operator<List<S>,List<S>>

public class HUXCrossover<S extends BinarySolution>
extends Object
implements CrossoverOperator<S>

This class allows to apply a HUX crossover operator using two parent solutions. NOTE: the operator is applied to the first encoding.variable of the solutions, and the type of the solutions must be Binary
