Interface SelectionOperator

All Known Implementing Classes:

TournamentSelection, TruncationSelection

public interface SelectionOperator

Provides the interface to a selection operator. This allows genomes to be selected for offspring production or elimination.

Method Summary

EvolutionaryAlgorithm	getTrainer()
int	performAntiSelection(Random rnd, Species species) Selects an unfit genome.
int	performSelection(Random rnd, Species species) Selects an fit genome.
