Engine.Setup<G,C>
public final class MLEvolutionStrategy<G extends Gene<?,G>,C extends Comparable<? super C>> extends Object implements Engine.Setup<G,C>
Setup for a (μ, λ)-Evolution Strategy. Applying this setup is done in the following way.And is equivalent to the following builder setup.final var engine = Engine.builder(problem) .setup(new MLEvolutionStrategy<>(μ, λ, p) .build();
final var engine = Engine.builder(problem) .populationSize(λ) .survivorsSize(0) .offspringSelector(new TruncationSelector<>(μ)) .alterers(new Mutator<>(p)) .build();
