Abstract: To solve the low capacity for high dimensional complex optimization problems, an improved artificial bee colony（BAABC） is proposed in this paper. In the stage of onlooker bees, BAABC algorithm has abandoned Roulette strategy which method onlooker bees selected nectar by, and the search way is changed for onlooker bees by introducing attractor. The attractor is generated by disturbing the global optimal solution. All onlooker bees move toward to the attractor in the same proportion. All onlooker bees together exploit the same area. So the exploitation capacity is enhanced. Experimental results show that the exploitation capacity of global search is remarkably enhanced. About the iteration number or time, convergence speed are improved obviously. To solve high dimensional complex optimization problem, the advantage of BAABC algorithm is obvious. What is more, the convergence performance of BAABC algorithm has nothing to do with the dimension of problem, and the robustness of BAABC is very strong.
