public class GPSpecies
extends Species

GPSpecies is a simple individual which is suitable as a species for GP subpopulations. GPSpecies' individuals must be GPIndividuals, and often their pipelines are GPBreedingPipelines (at any rate, the pipelines will have to return members of GPSpecies!).

Method Summary

Parameter	defaultBase() Returns the default base for this prototype.
Individual	newIndividual(EvolutionState state, java.io.DataInput dataInput) Provides an individual read from a DataInput source, including the fitness.
Individual	newIndividual(EvolutionState state, int thread) Provides a brand-new individual to fill in a population.
Individual	newIndividual(EvolutionState state, java.io.LineNumberReader reader) Provides an individual read from a stream, including the fitness; the individual will appear as it was written by printIndividual(...).
void	setup(EvolutionState state, Parameter base) The default version of setup(...) loads requested pipelines and calls setup(...) on them and normalizes their probabilities.

Method Detail

defaultBase

public Parameter defaultBase()

Description copied from interface: Prototype

Returns the default base for this prototype. This should generally be implemented by building off of the static base() method on the DefaultsForm object for the prototype's package. This should be callable during setup(...).

setup

public void setup(EvolutionState state,
                  Parameter base)

Description copied from class: Species

The default version of setup(...) loads requested pipelines and calls setup(...) on them and normalizes their probabilities. If your individual prototype might need to know special things about the species (like parameters stored in it), then when you override this setup method, you'll need to set those parameters BEFORE you call super.setup(...), because the setup(...) code in Species sets up the prototype.

newIndividual

public Individual newIndividual(EvolutionState state,
                                int thread)

Description copied from class: Species

Provides a brand-new individual to fill in a population. The default form simply calls clone(), creates a fitness, sets evaluated to false, and sets the species. If you need to make a more custom genotype (as is the case for GPSpecies, which requires a light rather than deep clone), you will need to override this method as you see fit.

Overrides:

newIndividual in class Species

newIndividual

public Individual newIndividual(EvolutionState state,
                                java.io.LineNumberReader reader)
                         throws java.io.IOException

Description copied from class: Species

Provides an individual read from a stream, including the fitness; the individual will appear as it was written by printIndividual(...). Doesn't close the stream. Sets evaluated to false and sets the species. If you need to make a more custom mechanism (as is the case for GPSpecies, which requires a light rather than deep clone), you will need to override this method as you see fit.

Overrides:

newIndividual in class Species

Throws:

java.io.IOException

newIndividual

public Individual newIndividual(EvolutionState state,
                                java.io.DataInput dataInput)
                         throws java.io.IOException

Description copied from class: Species

Provides an individual read from a DataInput source, including the fitness. Doesn't close the DataInput. Sets evaluated to false and sets the species. If you need to make a more custom mechanism (as is the case for GPSpecies, which requires a light rather than deep clone), you will need to override this method as you see fit.

Overrides:

newIndividual in class Species

Throws:
