Welcome to the jMetal Web site
jMetal Metal stands for Metaheuristic Algorithms in Java, and it is an object-oriented Java-based framework aimed at the development, experimentation, and study of metaheuristics for solving multi-objective optimization problems. jMetal provides a rich set of classes which can be used as the building blocks of multi-objective metaheuristics; taking advantage of code-reusing, the algorithms share the same base components, such as implementations of genetic operators and density estimators, thus facilitating the development of new multi-objective algorithms.
We have implemented a number of multi-objective metaheuristics using jMetal, and many problems usually included in performance studies are currently available in the framework. jMetal also provides quality indicators to performance assessing as well as a set of utilities that help in carrying out experimental studies.
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, but it is far from be a finished product. We are continuously modifying and extending jMetal according to our needs and those suggested by people interested in using it.
