Class SpliceNoRepeat

java.lang.Object

org.encog.ml.genetic.crossover.SpliceNoRepeat

All Implemented Interfaces:

EvolutionaryOperator

public class SpliceNoRepeat
extends java.lang.Object
implements EvolutionaryOperator

A simple cross over where genes are simply "spliced". Genes are not allowed to repeat. This method only works with IntegerArrayGenome.

Method Detail

performOperation

public void performOperation(java.util.Random rnd,
                             Genome[] parents,
                             int parentIndex,
                             Genome[] offspring,
                             int offspringIndex)

Perform the evolutionary operation.

Specified by:

performOperation in interface EvolutionaryOperator

Parameters:

rnd - A random number generator.

parents - The parents.

parentIndex - The index into the parents array.

offspring - The offspring.

offspringIndex - An index into the offspring array.

offspringProduced

public int offspringProduced()

Specified by:

offspringProduced in interface EvolutionaryOperator

Returns:

The number of offspring produced, which is 2 for splice crossover.

parentsNeeded

public int parentsNeeded()

Specified by:

parentsNeeded in interface EvolutionaryOperator

Returns:

The number of parents needed.

init

public void init(EvolutionaryAlgorithm theOwner)

Called to setup the evolutionary operator.

Specified by:

init in interface EvolutionaryOperator

Parameters:

theOwner - The evolutionary algorithm used with this operator.
