In this paper, a Structured Differential Evolution (StDE) that has multiple populations, or islands, is proposed. Since various characteristic strategies have been contrived for DE, the proposed StDE uses different strategies in respective islands. This technique is called mixed strategies. Therefore, it can be expected that the proposed StDE is effective for a wide range of optimization problems. Although various networks among islands are reported for island-based evolutionary algorithms, the most common one, namely the ring network is employed by StDE. However, in order to enhance the performance of proposed StDE, various migration policies are examined in the ring network though a variety of benchmark problems.
