Constructor Detail

Splice

public Splice(int theCutLength)

Create a slice crossover with the specified cut length.

Parameters:

theCutLength - The cut length.

Method Detail

performOperation

public void performOperation(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.
