jMetal: a framework for multi-objective optimization with metaheuristics

jMetal 5 Development Site

jMetal is an object-oriented Java-based framework for multi-objective optimization with metaheuristics The Web page of the project is: http://jmetal.github.io/jMetal/. Former jMetal versions can be found in SourceForge.

The current jMetal development version is hosted in this repository; this way, interested users can take a look to the new incoming features in advance.

If you are interested in contributing with your ideas and comments, please take a look the current discussions in the Issues section.
