updateApplicableClass

private void updateApplicableClass()

getApplicableClass

public java.lang.Class getApplicableClass()

Description copied from interface: ReproductionAlgorithm

Returns the class of individuals handled by this reproduction algorithm.

Specified by:

getApplicableClass in interface ReproductionAlgorithm

Returns:

The required type of the array-members in the parameter parents to the method ReproductionAlgorithm.reproduce.

reproduce

public Individual[] reproduce(Individual[] parents,
                              GAParameterSet params)

Description copied from interface: ReproductionAlgorithm

Reproduces the specified individuals.

Specified by:

reproduce in interface ReproductionAlgorithm

Parameters:

parents - The individuals to reproduce. The type of objects in this array must be the class returned by getApplicableClass. The number of objects in this array must be the same as returned by getRequiredNumberOfParents.

params - Experiment parameters.

Returns:

The children - i.e. the result of the reproduction of parents.

getRequiredNumberOfParents

public int getRequiredNumberOfParents()

Description copied from interface: ReproductionAlgorithm

Returns, how many individuals are required to produce one new individual whwn using this reproduction algorithm. If any number of parents is permitted (e.g. for most kinds of mutation), this method should return -1.

Specified by:

getRequiredNumberOfParents in interface ReproductionAlgorithm

Returns:

The required length of the array-parameter parents to the method reproduce or -1 if any length is parmitted.
