org.opt4j.core.genotype.SelectMapGenotype<K,V>

Type Parameters:

K - the type of keys

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>, MapGenotype<K,V>

public class SelectMapGenotype<K,V>
extends IntegerGenotype
implements MapGenotype<K,V>

The SelectMapGenotype selects for each key an element from a given list.

Example problem: Choose for each of five balls ball₁, ball₂, ball₃, ball₄, ball₅ a color. Available colors are blue, green, and red.
Example usage:

 SelectMapGenotype<Ball, Color> genotype = new SelectMapGenotype<Ball, Color>(Arrays.asList(ball1, ball2, ball3, ball4,
                ball5), Arrays.asList(Color.BLUE, Color.GREEN, Color.RED));
 genotype.init(new Random());
 

Example instance: [ball1=green, ball2=red, ball3=red, ball4=blue, ball5=blue]
Example search space size: 3⁵
