摘要 针对粒子群优化算法容易早熟、收敛精度低等问题,基于群体多样性反馈的思想,提出一种动态学习对象的粒子群优化算法。该算法采用群体多样性动态控制粒子的学习对象,减缓群体多样性的丧失速度,有利于群体的全局寻优。对3种典型多峰函数的仿真结果表明,该算法可以有效避免早熟问题,具有较好的全局寻优能力。 To overcome the disadvantage of Particle Swarm Optimization(PSO) algorithm such as premature,bad convergence precision,based on feedback of swarm diversity,a PSO algorithm with Dynamic Learning Objects(PSO-DLO) is presented.In the algorithm swarm diversity is used to control the learning objects,the strategy relieves the lost of swarm diversity,which is helpful for the global search.Experiments of three typical multi-modal functions indicate that the algorithm can effectively avoid premature and achieve better global search ability.
