基于高斯-柯西混合变异的多目标粒子群算法OACSTPCD

Aiming at the defects of poor convergence performance,insufficient global search ability and easy to fall into local optimization in MOPSO optimization algorithm for solving complex multi-objective optimization problems,a multi-objective parti-cle swarm optimization algorithm based on Gaussian-Cauchy mixed mutation(GC-MOPSO)is proposed.The algorithm uses a muta-tion disturbance mechanism of mixed Gaussian mutation and Cauchy mutation to improve the local and global search ability of parti-cles,and uses the tournament selection mechanism to select the global optimal individual in the external file to increase the diversi-ty of the population.The advantages of the algorithm are verified by comparing with six other algorithms in anti-generation distance(IGD).
