Welcome to the jMetal Web Site

jMetal is ...

jMetal stands for Metaheuristic Algorithms in Java, and it is an object-oriented Java-based framework for multi-objective optimization with metaheuristics.

This Web site is devoted to jMetal 4.5. The Web of the new version, jMetal 5.0 is hosted here.

You can use it to ...

The object-oriented architecture of the framework and the included features allow you to: experiment with the provided classic and state-of-the-art techniques, develop your own algorithms, solve your optimization problems, integrate jMetal in other tools, etc.

Our motivation is ...

The motivation driving us is to provide the programs we use in our own works to the multi-objective optimization research community. We have made an effort in trying to produce an ease-to-use software, and we are continuously modifying and extending jMetal according to our needs and those suggested by people interested in using it.

Only multi-objective algorithms?

Developing single-objective versions from multi-objective algorithms is usually an easy task, so jMetal contains also single-objective genetic algorithms, evolution strategies, PSO, and DE. An exception is CMA-ES, which currently does not have a multi-objetive counterpart.
