public class CrossoverReproducer<GenomeType>
extends Object
implements Reproducer<GenomeType>

The CrossoverReproducer takes a population of genomes, and applies the supplied CrossoverFunction to produce a new population.

Constructor Detail

CrossoverReproducer

public CrossoverReproducer(Selector<GenomeType> selector,
                           CrossoverFunction<GenomeType> crossoverFunction)

Creates a new instance of CrossoverReproducer

Parameters:

selector - The selector for the population to use.

crossoverFunction - The crossover function to use.

Method Detail

reproduce

public ArrayList<GenomeType> reproduce(Collection<EvaluatedGenome<GenomeType>> genomes)

Produces a new population of genomes from the supplied population using crossover. It works by using the selector to select two sets of genomes and then crosses them over.

Specified by:

reproduce in interface Reproducer<GenomeType>

Parameters:

genomes - The population to reproduce.

Returns:

The new population.

getSelector

public Selector<GenomeType> getSelector()

Gets the selector.

Returns:

The selector.

getCrossoverFunction

public CrossoverFunction<GenomeType> getCrossoverFunction()

Gets the CrossoverFunction.

Returns:

The CrossoverFunction.

setSelector

public void setSelector(Selector<GenomeType> selector)

Sets the selector.

Parameters:

selector - The new selector.

setCrossoverFunction

public void setCrossoverFunction(CrossoverFunction<GenomeType> crossoverFunction)

Sets the CrossoverFunction.

Parameters:

crossoverFunction - The new CrossoverFunction.
