Uses of Fitness in ec

Fields in ec declared as Fitness

Fitness	Species.f_prototype The prototypical fitness for individuals of this species.
Fitness	Individual.fitness The fitness of the Individual.

Methods in ec with parameters of type Fitness

abstract boolean	Fitness.betterThan(Fitness _fitness) Should return true if this fitness is clearly better than _fitness; You may assume that _fitness is of the same class as yourself.
abstract boolean	Fitness.equivalentTo(Fitness _fitness) Should return true if this fitness is in the same equivalence class as _fitness, that is, neither is clearly better or worse than the other.
