Class HUX

java.lang.Object
  org.moeaframework.core.operator.binary.HUX

All Implemented Interfaces:

Variation

public class HUX
extends Object
implements Variation

Half-uniform crossover (HUX) operator. Half of the non-matching bits are swapped between the two parents.

This variation operator is type-safe.

Constructor Summary

HUX(double probability)
Constructs a HUX operator.

Method Summary

static void	evolve(BinaryVariable v1, BinaryVariable v2) Evolves the specified variables using the HUX operator.
Solution[]	evolve(Solution[] parents) Evolves one or more parent solutions (specified by getArity) and produces one or more child solutions.
int	getArity() Returns the number of solutions that must be supplied to the evolve method.

Constructor Detail

HUX

public HUX(double probability)

Constructs a HUX operator.

Parameters:

probability - the probability of applying this operator

Method Detail

evolve

public Solution[] evolve(Solution[] parents)

Description copied from interface: Variation

Evolves one or more parent solutions (specified by getArity) and produces one or more child solutions. By contract, the parents must not be modified. The copy constructor should be used to create copies of the parents with these copies subsequently modified.

Specified by:

evolve in interface Variation

Parameters:

parents - the array of parent solutions

Returns:

an array of child solutions

evolve

public static void evolve(BinaryVariable v1,
                          BinaryVariable v2)

Evolves the specified variables using the HUX operator.

Parameters:

v1 - the first variable

v2 - the second variable

getArity

public int getArity()

Description copied from interface: Variation

Returns the number of solutions that must be supplied to the evolve method.

Specified by:

getArity in interface Variation

Returns:

the number of solutions that must be supplied to the evolve method
