- public class MuPlusLambdaBreeder
- extends MuCommaLambdaBreeder
MuPlusLambdaBreeder is a Breeder which, together with ESEvolutionState
and ESSelection, implements the (mu + lambda) breeding strategy and gathers
the comparison data you can use to implement a 1/5-rule mutation mechanism.
Note that MuPlusLambdaBreeder increases subpopulation sizes by their mu
values in the second generation and keep them at that size thereafter.
For more information, see the ESEvolutionState class documentation.
