Direct Known Subclasses:

DoubleMapGenotype

public class DoubleGenotype
extends java.util.ArrayList<java.lang.Double>
implements ListGenotype<java.lang.Double>

The DoubleGenotype consists of double values that can be used as a Genotype.

Example problem: Select filling level of five bottles
Example usage:

 DoubleGenotype<Switch> genotype = new DoubleGenotype();
 genotype.init(new Random(), 5);
 

Example instance: [0.5035947840006195, 0.9693492473483428, 0.12786372316728167, 0.5299369900029843, 0.8055193291478467]
Example search space size: [0;1]⁵
