Description
Class Summary | |
SPEA2Breeder | Breeds each subpopulation separately, with no inter-population exchange, and using the SPEA2 approach. |
SPEA2Evaluator | The SPEA2Evaluator is a simple, non-coevolved generational evaluator which evaluates every single member of every subpopulation individually in its own problem space. |
SPEA2MultiObjectiveFitness | SPEA2MultiObjectiveFitness is a subclass of Fitness which implements basic multiobjective fitness functions along with support for the ECJ SPEA2 (Strength Pareto Evolutionary Algorithm) extensions. |
SPEA2Subpopulation | SPEA2Subpopulation is a simple subclass of Subpopulation which adds the archiveSize field. |
SPEA2TournamentSelection | Does a simple tournament selection, limited to the subpopulation it's working in at the time and only within the boundry of the SPEA2 archive (between 0-archiveSize). |
This is an implementation of the Strength Pareto Evolutionary Algorithm for the ECJ package.
Details of this approach can be found in the following paper:
