JEMOA

Java Evolutionary Multi-Objective Algorithms, this version was developed with Java 11.

Data type

• Integer
• Real (double)
• Interval
• Fuzzy Number (Trapezoidal)

Problems

• PSP
• Knapsack
• DTLZ
• ZDT

Algorithms

• For single-objective:
  • GA: a genetic algorithm.
  • GWO: Grey Wolf Optimizer
• For multi-objective optimization:
  • GA: A multi-objectve evolutionary algorithm (using dominance)
  • NSGA-II
  • NSGA-III
  • NSGA-III-P : NSGA-III with preferences incorporation, using a multi-criteria ordinal classifier
  • MOGWO : Multi-Objective Grey Wolf Optimizer
  • MOGWO/DE: Multi-Objective Grey Wolf Optimizer based on decomposition
  • MOGWO-V : Multi-Objective Grey Wolf Optimizer with SBX crossover and Polynomial mutation
  • MOGWO-P : Multi-Objective Grey Wolf Optimizer with preferences incorporation, using a multi-criteria ordinal classifier
  • MOGWO-O : Multi-Objective Grey Wolf Optimizer with preferences incorporation, using a net outranking score
  • iMOACO_R : Indicator-Based Multi-Objective Ant Colony Optimization Algorithm for Continuous Search Spaces
  • GWO-InClass: Multi-Objective Grey Wolf Optimizer with InterClass-nC
  • ACO-InClass: Indicator-Based Multi-Objective Ant Colony Optimization Algorithm for Continuous Search Spaces with InterClass-nC

Multi-criteria Decision Aid (MCDA)

• Electre Tri
• INTERCLASS-nC
• INTERCLASS-nB
• SatClassifier

Execution DTLZ Test

To compile and run from command line the test suite it is necessary to execute the following maven goal:

$ mvn clean compile package 

For run

$ java -jar jemoa-1.0.0-jar-with-dependencies.jar -a NSGAIII -m 3   

It is required to have a directory -relative to the execution directory- with the instances in the following form:

DTLZ_INSTANCES/numberOfObjectives/DTLZ$N$_Instance.txt

Where N is the number of DTLZ problem. For more details use the --help

Examples

There are examples of how to execute each algorithm in the EXAMPLE package, it is only necessary to execute the class of interest, this from an IDE.
E.G. NSGA-III solving DTLZ problem.
