A niche genetic algorithm with population migration strategy

A niche genetic algorithm with population migration strategy (PMGA) is proposed in this paper in order to solve the multi-modal function optimization problem. This algorithm draws lessons from the migration phenomenon of human society. Through analyzing the validity of using PMGA to solve the multi-modal function optimization problem, testing three standardized one-dimensional multi-modal functions and comparing the experimental data of the PMGA with the data of relevant literatures´ algorithms, we finally validate that the PMGA proposed in this paper has advantages in precision of calculation and maintenance of population´s diversity.
