java.lang.Objectec.Species
public abstract class Species
Species is a prototype which defines the features for a set of individuals in the population. Typically, individuals may breed if they belong to the same species (but it's not a hard-and-fast rule). Each Subpopulation has one Species object which defines the species for individuals in that Subpopulation.
Species are generally responsible for creating individuals, through their newIndividual(...) method. This method usually clones its prototypical individual and makes some additional modifications to the clone, then returns it. Note that the prototypical individual does not need to be a complete individual -- for example, GPSpecies holds a GPIndividual which doesn't have any trees (the tree roots are null).
Species also holds a prototypical breeding pipeline meant to breed this individual. To breed individuals of this species, clone the pipeline and use the clone.
Parameters
base.ind classname, inherits and != ec.Individual |
(the class for the prototypical individual for the species) |
base.numpipes int >= 1 |
(total number of breeding pipelines for the species) |
base.pipe classname, inherits and != ec.BreedingPipeline |
(the class for the prototypical Breeding Pipeline) |
Parameter bases
base.ind | i_prototype (the prototypical individual) |
base.pipe | pipe_prototype (breeding pipeline prototype) |
base.fitness | f_prototype (the prototypical fitness) |

java.lang.Object |
clone()
Creates a new individual cloned from a prototype, and suitable to begin use in its own evolutionary context. |
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. |

public java.lang.Object clone()
Prototype
Typically this should be a full "deep" clone. However, you may share certain elements with other objects rather than clone hem, depending on the situation:
