In order to solve the problem of Cuckoo Search(CS)algorithm, a new Elite Cuckoo Search algorithm with Gravitational search and Gauss perturbation(GGECS)is proposed. In this algorithm, a self-adaptive control strategy is put forward to adjust step size factor and discovery probability dynamically in cuckoo algorithm. Besides, the population is classified by using the Pareto principle. Gravity search and Gaussian perturbation are applied to the bird's nests which belong to different population. By this method...
