摘要: 传统的粒子群优化算法((Particle Swarm Optimization,PSO )在更新粒子的速度时忽略了各粒子间的差异,在一次迭代中,各粒子采用相同的惯性权值来更新粒子的速度。为了体现各粒子的差异,提出了一种基于距离度量的自适应模糊粒子群优化算法(Distance-based Adaptive Fuzzy Particle Swarm Optimization, DAFPSO)。DAFPSO根据各粒子与最优粒子的差异,设计了相应的隶属函数来自适应地调整粒子的惯性权值。通过基准测试函数对算法进行了实验,从而验证了DAFPSO算法的有效性。

关键词: 粒子群,距离度量,惯性权值,模糊集,隶属函数

Abstract: The classical Particle Swarm Optimization (PSO) neglects the difference among particles while updating a particle's velocity in a generation. I}o cope with this issue, a novel Distanccbased Adaptive Fuzzy Particle Swarm Optimization (DAFPSO) was proposed in this paper. The DAFPSO designed membership functions to tune the basic parameters used in updating a particle's velocity according to the distance between the current particle and the global best particle. Several classical benchmark functions were used to evaluate the (DAFPSO.The experiments demonstrate the efficiency and effectiveness of the proposed DAFPSO.
