Self-adaptive differential evolution algorithm with improved mutation mode

The optimization performance of the Differential Evolution algorithm (DE) is easily affected by its control parameters and mutation modes, and their settings depend on the specific optimization problems. Therefore, a Self-adaptive Differential Evolution algorithm with Improved Mutation Mode (IMMSADE) is proposed by improving the mutation mode of DE and introducing a new control parameters adaptation strategy. In IMMSADE, each individual in the population has its own control parameters, and they would be dynamically adjusted according to the population diversity and individual difference. IMMSADE is compared with the basic DE and the other state-of-the-art DE algorithms by using a set of 22 benchmark functions. The experimental results show that the overall performance of the proposed IMMSADE is better than the basic DE and the other compared DE algorithms.
