摘要 将物理退火过程中的等温阶段引入到粒子群算法的迭代寻优过程中,采用动态惯性权重改进了粒子状态更新规则和全局最优的判定规则。仿真结果表明,退火优化效果和收敛性均有所改善。 A simulated annealing particle swarm optimization(Particle Swarm Optimization,PSO) algorithm is introduced into the isothermal phase in the physical annealing process. The dynamic inertia weight is used to improve the particle state update rule and the global optimal decision rule. Simulation results show that the annealing process is optimized and convergent.
