org.opt4j.core.genotype.SelectGenotype<V>

Type Parameters:

V - the type of elements

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<java.lang.Integer>, java.util.Collection<java.lang.Integer>, java.util.List<java.lang.Integer>, java.util.RandomAccess, Genotype, ListGenotype<java.lang.Integer>

public class SelectGenotype<V>
extends IntegerGenotype

The SelectGenotype selects for each index an element from the given list.

Example problem: Draw five times from an urn which contains three balls and return the ball after each draw.
Example usage:

 SelectGenotype<Ball> genotype = new SelectGenotype<Ball>(Arrays.asList(ball1, ball2, ball3));
 genotype.init(new Random(), 5);
 

Example instance: [0=ball3, 1=ball2, 2=ball2, 3=ball1, 4=ball3]
Example search space size: 3⁵
