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 | +---------------------+------------------------------------+
