Class MuLambdaBreederCGP

java.lang.Object
  ec.Breeder

All Implemented Interfaces:

ec.Setup, ec.Singleton, java.io.Serializable

public class MuLambdaBreederCGP
extends ec.es.MuPlusLambdaBreeder

The CGP implementation requires this slightly modified MuPlusLambdaBreeder when using Evolutionary Strategies. Its sole purpose is to reset string representations of the expressions represented by all genomes in the population. Resetting forces re-computation of each expression during evaluation of CGP nodes, but only for the first such evaluation.
