In a genetic algorithm, there are different steps. One of those steps is the selection of chromosomes for reproduction. What are the available selection strategies in genetic algorithms?
There are several selection methods. Just to mention a few:
Fitness proportionate selection (a.k.a. roulette wheel selection)
In the paper Selection Methods for Genetic Algorithms, by Khalid Jabari, a comparison study between several selection methods is described. See also the paper A comparative analysis of selection schemes used in genetic algorithms by David E. Goldberg and Kalyanmoy Deb.
