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,java.lang.Integer>

public class IntegerMapGenotype<K>
extends IntegerGenotype
implements MapGenotype<K,java.lang.Integer>

The IntegerMapGenotype is a IntegerGenotype with the MapGenotype functionality.

Example problem: Select the outcome of throwing five dice die₁, die₂, die₃, die₄, die₅
Example usage:

 IntegerGenotype<Die> genotype = new IntegerMapGenotype<Die>(Arrays.asList(die1, die2, die3, die4, die5), 1, 6);
 genotype.init(new Random());
 

Example instance: [die1=3, die2=5, die3=6, die4=1, die5=3]
Example search space size: 6⁵
