jMetal Development Site

jMetal is an object-oriented Java-based framework for multi-objective optimization with metaheuristics
(http://jmetal.sourceforge.net).

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.

After eight years since the first release of jMetal, we have decided it's time to make a deep redesign of the
software. Some of the ideas we are elaborating are:

  • Maven is used as the tool for development, testing, packaging and deployment.
  • The encoding takes into account the recommendations provided in “Clean code: A Handbook of Agile Software Craftsmanship" (Robert C. Martin)
  • The Fluent Interface (http://martinfowler.com/bliki/FluentInterface.html) is applied to configure and execute
    the algorithms.
  • We will incorporate progressively unit tests to all the classes.

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

Features of the current development version:

  • Algorithms: NSGA-II, NSGA-III (to be tested), SMPSO, GDE3, IBEA (corrected version), MOEA/D (variants: MOEA/D-DE, MOEA/D-DRA, Constrained MOEA/D).
  • Encodings: Binary, Real, Integer, Permutation, Integer+Double
  • Crossover operators: SBXCrossover, SinglePointCrossover, DifferentialEvolutionCrossover, IntegerSBXCrossover, BLXAlphaCrossover, HUXCrossover
  • Mutation operators: PolynomialMutation, SingleRandomMutation, BitFlipMutation, IntegerPolynomialMutation, UniformMutation, NonUniformMutation
  • Selection operators: BinaryTournamentSelection, DifferentialEvolutionSelection, RankingAndCrowdingSelection, NaryTournamentSelection
  • Problems: Fonseca, Kursawe, Schaffer, Srinivas, OneZeroMax, NMMin, NMIN2, ZDT benchrmark, DTLZ benchmark, WFG benchmark, LZ09 benchmark
  • Qualitity indicators: Epsilon, Hypervolume, error ratio, spread, seneralized spread, generational distance, inverted generational distance, set coverage.

jMetal is available as a Maven Project in The Central Repository
