Class MpLEvolutionStrategy<G extends Gene<?,G>,C extends Comparable<? super C>>

java.lang.Object
io.jenetics.ext.MpLEvolutionStrategy<G,C>
Type Parameters:
G - the gene type
C - the fitness result type
All Implemented Interfaces:
Engine.Setup<G,C>

public final class MpLEvolutionStrategy<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.
final var engine = Engine.builder(problem)
    .setup(new MpLEvolutionStrategy<>(μ, λ, p))
    .build();
And is equivalent to the following builder setup.
final var engine = Engine.builder(problem)
    .populationSize(λ)
    .survivorsSize(μ)
    .offspringSelector(new TruncationSelector<>(μ))
    .alterers(new Mutator<>(p))
    .build();
