public class SimpleBoundedFitness
extends SimpleFitness

A SimpleBoundedFitness is a SimpleFitness with an arbitrary upper bound. Once the fitness exceeds this bound the fitness is considered to be "ideal".

Method Detail

setup

public void setup(EvolutionState state,
                  Parameter base)

Description copied from interface: Prototype

Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.

For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.

isIdealFitness

public boolean isIdealFitness()

Description copied from class: Fitness

Should return true if this is a good enough fitness to end the run

Overrides:

isIdealFitness in class SimpleFitness

betterThan

public boolean betterThan(Fitness fitness)

Description copied from class: Fitness

Should return true if this fitness is clearly better than _fitness; You may assume that _fitness is of the same class as yourself. For any two fitnesses fit1 and fit2 of the same class, it must be the case that fit1.equivalentTo(fit2) == fit2.equivalentTo(fit1), and that only one of fit1.betterThan(fit2), fit1.equivalentTo(fit2), and fit2.betterThan(fit1) can be true.
