**5.7 Elitism of RGSGCS algorithm**

Besides the standard genetic operators (i.e., crossover and mutation operators). The elitism Phase is used finally to preserve the best candidates for the next generation, so that the algorithm always converges to the global optimum. It combines the parent population with the modified population (the candidates generated by crossover and Mutation operators), and takes the best chromosomes. After this phase, the algorithm continues to the next iteration. The algorithm terminates after it reaches the maximum generations number.
