SIMPLE_GA\ A Simple Genetic Algorithm {#simple_ga-a-simple-genetic-algorithm align=”center”} ==========================


SIMPLE_GA is a C++ program which implements a simple genetic algorithm, by Dennis Cormier and Sita Raghavan.

Here, we consider the task of constrained optimization of a scalar function. That is, we have a function F(X), where X is an M-vector satisfying simple constraints for each component I:

        X_MIN[I] <= X[I] <= X_MAX[I]

and, subject to those constraints, we seek a vector X which maximizes the value F(X).

In the example given here, the spatial dimension M is 3, the function F(X) is X[1]\^2 - X[1]*X[2] + X[3], and the constraints are

        0 <= X[1] <= 5
        0 <= X[2] <= 5
       -2 <= X[3] <= 2

The correct solution is [5,0,2].
