All Implemented Interfaces:

Prototype, Setup, SimpleProblemForm, Serializable, 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).
