In a roulette wheel selection, the circular wheel is divided as described before. It is to be noted that fitness proportionate selection methods don't work for. The normal method used is the roulette wheel (as shown in Figure 2 above). The following table lists a sample population of 5 individuals (a typical population of. The simplest selection scheme is roulette - wheel selection, also called stochastic sampling with replacement [Bak87].

Maybe it could be the fitness of each member, or a value inversely proportional to the member's position in the "top 50". But I think that doesn't happen much in practice and from my experience; for example in genetic algorithms the fitness weights are always changing. The fitness assigned to each individual depends only on its position in the individuals rank and not on the actual objective value. Having said that, the following code is more appropriate if the selection size is unitary and if you do not assume how the probabilities are calculated and zero probability value is allowed. I think that is definitely a lower bound regardless: Here is a simple python implementation of that pseudocode: This is the fastest one I've encountered.
