To improve the real-coded searching ability of the Biogeography-Based Optimization(BBO) algorithm,this paper presented a hybrid algorithm BBO/DEs based on Differential Evolution(DE).In order to solve the prematurity of BBO,the algorithm incorporated the search performance of differential evolution and the utilization performance of BBO.And a Levy mutation strategy was introduced to enhance population diversity.Finally suitable trial vector was chosen by comparison.Some correlation algorithms were compared on high-dimensional benchmark functions.The experimental results show that without losing the original ability the proposed algorithm can improve the searching ability,and it has higher efficiency in terms of search accuracy and speed.
