Roulette Selection in Genetic Algorithms
Can anyone provide some pseudo code for a roulette selection function? How would I implement this: I don't really understand how to read this math notation. I never took any probability or statistics. ...

Hi all. In a genetic algorithm, when selecting members for crossover using roulette-wheel selection method, does the population first need to be sorted by fitness rank? The possibilities seem to be: sort population first by ascending fitness sort population by descending fitness don't sort population & let the roulette ball fall wher...
I am currently writing a keyboard layout optimization algorithm in C (such as the one designed by Peter Klausler) and I want to implement a fitness-proportionate selection as described here (PDF Link): With roulette selection you select members of the population based on a roullete wheel model. Make a pie chart, where the ar...
I am implementing a roulette wheel selection, and I would like to keep as much code as possible in SQL. My attempt has yielded the query below. $1 is a random variable of the same range as weight I send to the SQL code (it was not clear how to make random() be called only once). Weight is the size of the row's slot on the wheel. rand...
I am attempting to write a Genetic Algorithm based on techniques I had picked up from the book "AI Techniques for Game Programmers" that uses a binary encoding and fitness proportionate selection (also known as roulette wheel selection) on the genes of the population that are randomly generated within the program in a two-dimensional arr...
Could somebody explain to me the architecture behind chatroulette? I was thinking about a similar project that would only implement Audio support (for starters). Is the best way to set this up a flash server? If so, how should I go about getting into flash, will I need flex 4? I have some beginner experience with c++, c# and java but I h...
So I've written a roulette selection function for my genetic algorithm which follows: public String tournament(float fitness, Chromosome pop[], int selection) { // roulette if (selection == 1) { Random random = new Random(); float slice = random.nextFloat() * fitness; float curFitness = 0.0f; ...
