Class HUXCrossover

java.lang.Object

org.uma.jmetal.operator.impl.crossover.HUXCrossover

All Implemented Interfaces:

Serializable, CrossoverOperator<BinarySolution>, Operator<List<BinarySolution>,List<BinarySolution>>

public class HUXCrossover
extends Object
implements CrossoverOperator<BinarySolution>

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
