jMetal: a framework for multi-objective optimization with metaheuristics

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:

• Architecture redesign to provide a simpler design while keeping the same functionality.
• Improve code quality:
• Application of unit testing
• Better use of Java features (e.g, generics)
• Design patterns
• Application of clean code guidelines - “Clean code: A Handbook of Agile Software Craftsmanship" (Robert C. Martin)
• Algorithm templates
• Parallelism support
• Algorithm measures
• Maven is used as the tool for development, testing, packaging and deployment.

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

##Components The current development version provides:

• Algorithms: NSGA-II, NSGA-III (to be tested), SMPSO, GDE3, IBEA, MOEA/D (variants: MOEA/D-DE, MOEA/D-DRA, Constrained MOEA/D), SPEA2, PESA2, AbYSS, MOCell, RandomSearch, SMS-EMOA
• 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, multiobjective TSP
• Qualitity indicators: Epsilon, Hypervolume, error ratio, spread, generalized spread, generational distance, inverted generational distance, set coverage.
