public class RankScaling<T extends Chromosome>
extends Scaling<T>

This operator implements the rank scaling. Rank scaling re-assigns the rank as fitness value to indiduals. The operator is compatible with multi-objective optimization. In that case, rank is in turn computed for each each objective.
