Selection (genetic algorithm)
Selection is the stage of a genetic algorithm in which individual genomes are chosen from a population for later breeding (recombination or crossover). Additional recommended knowledgeThere are several generic selection algorithms, such as tournament selection, fitness proportionate selection, and roulette wheel selection. This last one can be implemented as follows:
There are other selection algorithms that do not consider all individuals for selection, but only those with a fitness value that is higher than a given (arbitrary) constant. Other algorithms select from a restricted pool where only a certain percentage of the individuals are allowed, based on fitness value. See the main article on genetic algorithms for more details. |
