jMetal is a Java-based framework for multi-objective optimization with metaheuristics. The last stable version is 6.1. The most recent documentation is hosted in https://jmetal.readthedocs.io.
The current development version (6.2-SNAPSHOT) is a Maven project structured in the following sub-projects:
| Sub-project | Contents |
|---|---|
| jmetal-core | Core classes |
| jmetal-solution | Solution encodings |
| jmetal-algorithm | Algorithm implementations |
| jmetal-problem | Benchmark problems |
| jmetal-lab | Experimentation and visualization |
| jmetal-parallel | Parallel extensions |
| jmetal-auto | Auto-design and configuration |
| jmetal-component | Component-based algorithms |
