在群体进化若干代后,将弱解空间删除,在以后的进化进程中以同样的群体大小只在强解空间进行群体的繁殖,则可加大强解空间的个体密度,提高解的精度,这样有助于性能优良的个体的产生,-After several generations of evolution in the population, a weak solution space removed in the future evolution of the process with the same population size in a strong solution space only breeding colony, it can increase the density of strong individual solution space, to improve the accuracy of the solution, This helps produce good performance of individuals,
