org.uncommons.watchmaker.framework.selection.RankSelection

A selection strategy that is similar to fitness-proportionate selection except that is uses relative fitness rather than absolute fitness in order to determine the probability of selection for a given individual (i.e. the actual numerical fitness values are ignored and only the ordering of the sorted population is considered).

Rank selection is implemented in terms of a mapping function ( {@link #mapRankToScore(int,int)}) and delegation to a fitness-proportionate selector. The mapping function converts ranks into relative fitness scores that are used to drive the delegate selector.
