The MOEA Framework is a free and open source Java library for developing and experimenting with multiobjective

evolutionary algorithms (MOEAs) and other metaheuristics.

### Features

* Fast, reliable implementations of over 25 MOEAs, including NSGA-III and MOEA/D.

* Suite of tools for comparing and statistically testing algorithms.

* Master-slave, island-model, and hybrid parallelization.

* Permissive open source license (LGPL)

### :warning: Upgrading to V5 :warning:

Version 5.0 was recently released, which includes breaking changes that will likely requiring code modifications if

upgrading from a previous version.  Refer to the [Release Notes](docs/releaseNotes.md) for details.

### Getting Started

Download the latest release from the [GitHub Releases](https://github.com/MOEAFramework/MOEAFramework/releases) page.  Maven users can add our

dependency to their `pom.xml` file:

```xml

    org.moeaframework

    moeaframework

    5.1

```

Check out our [examples](https://github.com/MOEAFramework/MOEAFramework/tree/master/examples),

[online documentation](https://github.com/MOEAFramework/MOEAFramework/blob/master/docs/README.md), and

[API Specification (Javadoc)](https://moeaframework.org/javadoc/index.html) to get started.

### Example

Below we solve the 2-objective DTLZ2 problem using NSGA-II:

```java

Problem problem = new DTLZ2(2);

NSGAII algorithm = new NSGAII(problem);

algorithm.run(10000);

algorithm.getResult().display();

```
