Extends the MOEA Framework with optimization algorithms implemented in JMetal. If using any of the JMetal algorithms, please cite:

When using Maven, add the following dependency to your pom.xml:
<dependency>
<groupId>org.moeaframework</groupId>
<artifactId>jmetal-plugin</artifactId>
<version>6.2.3</version>
</dependency>Otherwise, download and add the .jar file from the Releases page
to the classpath, which is typically the MOEAFramework/lib/ folder. Note we also publish a -jar-with-dependencies
version that includes the appropriate version of JMetal.
We aim to support the latest version of JMetal, however, there may be some delay after a new release. The {major}.{minor} version
number of this project will match the supported JMetal version. Below is a complete list of supported versions:
| JMetal Version | JMetal-Plugin Latest | Supported MOEA Framework Versions | Supported Java Versions |
|---|---|---|---|
6.2 |
6.2.3 |
>= 4.0 |
>= 17 |
6.2 |
6.2.0 |
3.6 - 3.11 |
>= 14 |
6.1 |
6.1.0 |
3.6 - 3.11 |
>= 14 |
6.0 |
6.0.1 |
3.5 - 3.11 |
>= 14 |
5.11 |
5.11.2 |
3.2 - 3.11 |
>= 14 |
Once this plugin is added as a Maven dependency, you can reference JMetal algorithms as you would any other:
NondominatedPopulation result = new Executor()
.withProblem("DTLZ2_3")
.withAlgorithm("AbYSS")
.withMaxEvaluations(10000)
.run();JMetal algorithms are configured by supplying properties to the Executor. We do not provide
a listing or explanation of these properties, but an easy way to figure out what properties are available
is to run:
TypedProperties properties = new TypedProperties();
new JMetalAlgorithms().getAlgorithm("ESPEA", properties, new DTLZ2(2));
System.out.println(String.join(", ", properties.getAccessedProperties()));which displays:
maxEvaluations, pm.distributionIndex, pm.rate, populationSize, replacementStrategy, sbx.distributionIndex, sbx.rate
Some functionality may not be available for JMetal algorithms. This includes the ability to instrument algorithms to collect runtime data. JMetal algorithms only generate the end-of-run Pareto approximation set.
Some algorithms are implemented in both JMetal and the MOEA Framework. If such cases, you can request the JMetal
version by appending -JMetal to the name, such as NSGAII-JMetal.
