WebSelection: At the beginning of the recombination process, individuals need to be selected to participate in mating. Depending on the crossover, a different number of parents need to be selected. Different kinds of selections can increase the convergence of the algorithm. Crossover: When the parents are selected, the actual mating is done. A ...

WebIn the experiments, the stopping criterion was the maximum number of the iterations which equals 1000. We used the mutation rate equalling 0.01, the probability crossover equalling 0.7, the population size equalling 350 individuals, the probability of 2-opt equalling 0.2. We applied the roulette and the ranking method for the population selection.
