public class SimpleBreeder
extends Breeder

Breeds each subpopulation separately, with no inter-population exchange, and using a generational approach. A SimpleBreeder may have multiple threads; it divvys up a subpopulation into chunks and hands one chunk to each thread to populate. One array of BreedingPipelines is obtained from a population's Species for each operating breeding thread.

public void setup(EvolutionState state,
                  Parameter base)
Description copied from interface: Setup
Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.

breedPopulation

public Population breedPopulation(EvolutionState state)
                           throws java.lang.CloneNotSupportedException
A simple breeder that doesn't attempt to do any cross- population breeding. Basically it applies pipelines, one per thread, to various subchunks of a new population.

breedPopChunk

public void breedPopChunk(Population newpop,
                          EvolutionState state,
                          int[] numinds,
                          int[] from,
                          int threadnum)
                   throws java.lang.CloneNotSupportedException
A private helper function for breedPopulation which breeds a chunk of individuals in a subpopulation for a given thread. Although this method is declared public (for the benefit of a private helper class in this file), you should not call it.
