Biogeography-Based Optimization algorithm is a new kind of global optimization algorithm,but its searching capability still needs to be improved.In order to improve the optimization characteristics of the algorithm,this paper proposes an improved algorithm of BBO——improved biogeography-based optimization algorithm based on local search strategy(ILSBBO).The improved approach combines the local search strategy of differential evolution with the migration strategy of BBO,then,the selection operation of differential evolution is introduced to it.Among 13 benchmark test functions,the improved algorithm,the original BBO,and hybrid differential evolution with biogeography-based optimization(DE/BBO) are compared,the results show that the proposed approach is better than the other two approaches.In addition,the convergence rate of the improved algorithm is also faster than the original biogeography-based optimization algorithm.
