MpLEvolutionStrategy (Jenetics 6.1.0)

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();

Since:

6.0

Version:

6.0
