Package org.opt4j.core.problem

package org.opt4j.core.problem

Provides the classes for the optimization problem. A problem is defined by the following classes:

Genotype

The Genotype is the genetic representation of an Individual. The package org.opt4j.genotype contains predefined Genotype classes that allow a modular assembly. Thus, usually you do not have to write your custom Genotype.

Phenotype

The Phenotype represents a solution of the optimization problem.

Creator

The task of the Creator is the creation of random Genotypes.

Decoder

The task of the Decoder is the decoding from a given Genotype to a corresponding Phenotype.

Evaluator

The task of the Evaluator is the evaluation of Phenotypes to the Objectives.

Additional information about the problem should be contained in an user defined class that is injected as needed.
