The DoubleMapGenotype is a DoubleGenotype with the MapGenotype functionality.

Example problem: Select filling level of five bottles bottle₁, bottle₂, bottle₃, bottle₄, bottle₅
Example usage:

 DoubleMapGenotype<Bottle> genotype = new DoubleMapGenotype<Bottle>(Arrays.asList(bottle1, bottle2, bottle3, bottle4,
                bottle5));
 genotype.init(new Random());
 

Example instance: [bottle1=0.5035947840006195,bottle2=0.9693492473483428 ,bottle3=0.12786372316728167 ,bottle4=0.5299369900029843,bottle5=0.8055193291478467]
