Class Summary

Class	Description
SPEA2Breeder	This subclass of SimpleBreeder overrides the loadElites method to build an archive in the top elites[subpopnum] of each subpopulation.
SPEA2Evaluator	This subclass of SimpleEvaluator evaluates the population, then computes auxiliary fitness data of each subpopulation.
SPEA2MultiObjectiveFitness	SPEA2MultiObjectiveFitness is a subclass of MultiObjectiveFitness which adds three auxiliary fitness measures used in SPEA2: strength S(i), kthNNDistance D(i), and a final fitness value R(i) + D(i).
SPEA2TournamentSelection	This is a special version of TournamentSelection which restricts the selection to only the archive region (the top 'archiveSize' elements in the subpopulation).
