- All Implemented Interfaces:
- Setup, Singleton, java.io.Serializable
public class SpatialBreeder
- extends SimpleBreeder
A slight modification of the simple breeder for spatially-embedded EAs.
Breeds each subpopulation separately, with no inter-population exchange,
and using a generational approach. A SpatialBreeder 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.
