A Topology Based on a Local World Evolving Model for PSO
In this paper, we proposed a LW-PSO (PSO using a local world evolving model) by combining a local world evolving model with the “survival of the fittest” evolution mechanism. The concept of population structural entropy, a new diversity measure is defined and used to control the evolution process of the population topology of LW-PSO so the balance between the exploration and exploitation can be preserved during the population evolution. The experimental results show that LW-PSO can outperform the standard PSO with the lbest topology and the gbest topology especially in the multimodal problems and the extra time cost is negligible.
