1) Roulette Wheel Selection Roulette wheel probabilistically selects individuals based on their fitness values Fi. A real-valued interval, S, is determined as either the sum of the individuals expected selection probabilities S =∑Pi, where ∑ = Fi Fi Pi or the sum of the raw fitness values S=∑Fi over all the individuals in the current population.Roulette Wheel Selection Search and download Roulette Wheel Selection open source project / source codes from CodeForge.com.

Intuitively, this example makes sense: 9 out of ten times the random number will fall between 1 and 9 causing the first element to be drawn with probability 0.9 (just as the weights specified).

Roulette wheel selection - Genetic Algorithm Implementation - 3 replies;. Straight C - 5 replies; Roulette - 3 replies; Translating from Matlab to C - 3 replies.For a large number of individuals the above algorithm might be computationally quite demanding. A simpler and faster alternative uses the so-called stochastic acceptance. If this procedure is repeated until there are enough selected individuals, this selection method is called fitness proportionate selection or roulette-wheel selection.You can see in following picture, how the situation changes after changing.
