摘要:根据萤火虫算法的特点,针对萤火虫算法较早进入局部收敛的不足进行改进,引入了“挡板效应”的方法,扩大种群多样性,并提出了BGSO算法。在分析了非线性盲源分离模型的基础上,利用系统两次遍历萤火虫群,比较评价函数,获得最优解的方式。其有效性被仿真结果所证实。
According to the characteristics of glowworm swarm optimization(GSO)algorithm
to overcome the disadvantages of premature convergence
a new method called “baffle effect”was proposed. The diversity of swarm was expanded. Based on the analysis of the model of nonlinear blind source separation(NBSS)
using traversing glowworm swarm twice
comparing evaluation function
the best result was get. Their validity is confirmed by effect of the signal separation test.
