      ec.app.sum.Sum

All Implemented Interfaces:

Prototype, Setup, SimpleProblemForm, java.io.Serializable, java.lang.Cloneable

public class Sum
extends Problem
implements SimpleProblemForm

Sum is a simple example of the ec.Vector package, implementing the very simple sum problem (fitness = sum over vector). This is a generalization of the common MaxOnes problem (fitness = number of 1's in vector).

void	describe(Individual ind, EvolutionState state, int threadnum, int log, int verbosity)
void	evaluate(EvolutionState state, Individual ind, int subpop, int threadnum) Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
