Interface Summary
Interface	Description
Genotype	The `Genotype` represents a marker interface.
IndividualFactory	The `IndividualFactory` is a creator for `Individual`s.
IndividualSetListener	The `IndividualSetListener` receives notifications if an `Individual` is added to or removed from an `IndividualSet`.
IndividualStateListener	The `IndividualStateListener` receives notifications of an `Individual` changing its `Individual.State`.
Value<V>	The `Value` represents the result for an `Objective`.

Class Summary
Class	Description
AbstractIndividualFactory<I extends Individual>	The `AbstractIndividualFactory` creates `Individual`s using a given `Provider` and sets the registered `IndividualStateListener`s.
DefaultIndividualFactory	The `DefaultIndividualFactory` is a creator for standard `Individual`s.
DoubleValue	The `DoubleValue` is a `Value` with a `Double` as value.
Individual	The `Individual` class forms a single solution for the given optimization problem.
IndividualSet	The `IndividualSet` is a `Set` of `Individual`s.
IntegerValue	The `IntegerValue` is a `Value` with an `Integer` as value.
Objective	The `Objective` is the identifier for a single objective in the `Objectives`.
Objectives	The `Objectives` contains the `Objective`-`Value`s pairs of an `Individual`.

Enum Summary
Enum Description

Individual.State
The possible states of an Individual.

Objective.Sign

Enum Summary
Enum	Description
Individual.State	The possible states of an `Individual`.
Objective.Sign	The sign of the `Objective`.

Package org.opt4j.core Description

Provides the classes that join the problem and optimizer.

This package contains the Individual and the related classes and interfaces. The Individual is a single solution of the optimization problem. It consists of the Genotype, the phenotype, and the Objectives, which are the representation of the Individual in the search space, the solution space, and the objective space, respectively.

Genotype: The Genotype is the genetic representation of an Individual. The package org.opt4j.genotype contains predefined Genotype classes like for binary strings or Double vectors that allow a modular assembly. For each optimization problem, the user needs to choose the genetic representation which fits the search space best.
phenotype: The phenotype Object is the decoded representation of an Individual.
Objectives: The Objectives contain the results of the evaluated Objectives for a phenotype. The Objectives represent the fitness of the Individual. To support multi-objective optimization, an Objective represents one dimension in the objective space. After the evaluation of the phenotype, the Objectives hold a Value for each Objective.

Individuals can be grouped in an IndividualSet which informs IndividualSetListeners when changed. New Individuals should be created using the IndividualFactory.
