Primal-Dual Genetic Algorithm(PDGA)has higher ability of global searching quickly and stochastically.It improves the searching ability in the searching space.But it can't make full use of system feedback information such that it iterates redundantly and its efficiency is reduced.Meanwhile,Ant Colony Optimization converges to the optimization path by information pheromone accumulation and renewal.It has the ability of parallel processing and global searching.Since there is little information pheromone on the...
