Hi, I used the following code to initialize the offspring array: def create_pop #Define an offspring array that will hold the copies of the @board array @offspring = [] 4.times{ @offspring << @board.clone } end At the moment everything is in one huge class 'class Game', though I plan to have one class for game setup, and one for the evolutionary algorithm.
