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

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

public class WeaselSelector<G extends Gene<?,G>,C extends Comparable<? super C>> extends Object implements Selector<G,C>
Selector implementation which is part of the Weasel program algorithm. The Weasel program is a thought experiment by Richard Dawkins to illustrate the functioning of the evolution: random mutation combined with non-random cumulative selection.

The selector always returns populations which only contains "count" instances of the best Phenotype.

Engine setup for the Weasel program:
final Engine<CharacterGene, Integer> engine = Engine.builder(problem)
     // Set the 'WeaselSelector'.
    .selector(new WeaselSelector<>())
     // Disable survivors selector.
    .offspringFraction(1)
     // Set the 'WeaselMutator'.
    .alterers(new WeaselMutator<>(0.05))
    .build();
