| 摘 要： | 对PSO方法中粒子运行规律给出较为完整的分析,考察随机性对粒子运动过程的影响,提出聚度的概念,并通过粒子的聚度考察粒子在实际运行条件下的分布情况,给出更加具体的参数设置区间,提出一种粒子在运动过程中的速度补偿策略,对于一些参数设置可以通过该策略提高搜索性能,该策略对实际应用中选择和调整PSO算法参数有较强的指导意义。 |
| 关 键 词： | 粒子群优化 聚度 速度补偿策略 |

| Abstract: | The particle's trajectory of PSO was fully analyzed in this paper,the influence of random parameters on particle's trajectory was discussed,the concept of cluster-degree was put forward and distribute status of particle with different cluster-degree was studied.The reasonable parameters setting range based on cluster-degree was proposed,at the same time,reinforce strategy of particle's velocity was proposed in order to improve performance of PSO under some condition.So this paper is helpful for the choosing... |
| Keywords: | Particle swarm optirniGation Cluster-degree Velocity reinforce strategy |
