jMetal project Web site

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

Comments and suggestions are welcome.
