All Implemented Interfaces:

Variation

public class UniformCrossover
extends Object
implements Variation

Crossover operator where each index is swapped with a specified probability.

Constructor Summary

UniformCrossover(double probability)
Constructs a uniform crossover operator with the specified probability an index is swapped between two solutions.

Method Summary

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.
double	getProbability() Returns the probability an index is swapped between two solutions.

Constructor Detail

UniformCrossover

public UniformCrossover(double probability)

Constructs a uniform crossover operator with the specified probability an index is swapped between two solutions.

Parameters:

probability - the probability an index is swapped between two solutions

Method Detail

getProbability

public double getProbability()

Returns the probability an index is swapped between two solutions.

Returns:

the probability an index is swapped between two solutions

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

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
