Aiming at the demerits of Multi-Island Genetic Algorithm (MIGA), the dynamic modulation of crossover and variable probability is employed to overcome the premature phenomenon and improve the searching efficiency of this al-gorithm. Combining with the powerful local searching ability of the simulated annealing algorithm, an improved MIGA with higher efficiency is worked out. Its optimization effect is verified by simulation and experiment. This improved algorithm can be effectively applied in the optimization of powertrain mounting system.
