Posted on March 22, 2021

The roulette wheel selection (also known as fitness proportionate selection) is a function used by genetic algorithms for selecting potentially useful solutions for recombination. The crossover individual probability is computed based on the individual’s fitness divided by the sum of all population fitness. The following is the formula for it: where pi is the probability of each chromosome equals the chromosome frequency divided by the sum of all fitness. Let’s imagine that the roulette wheel selection algorithm is like aRead More
