Evolutionary Algorithm

Topic: Computational Intelligence, Date: 01/02/2016


This Evolutionary Algorithm is a very simple one in which a string of characters will eventually be evolved towards, starting from a random string of characters. The individual's fitness will be ranked depending on the distance from the desired string so that only the individuals which are closer to the destination will be chosen for mutation and crossover by a roulette wheel selection method.

This project was created as a challenge to myself and a way of revising for a Computational Intelligence module. It was stemmed from a practical, in which we just had to implement the mutation and crossover. However, I thought that was too easy so I decided to create the toy problem's solution from scratch.



EvolutionaryAlgorithm evo = new EvolutionaryAlgorithm(50, "Evolutionary Algorithm");
