To solve the problem, a fuzzy clustering based on predator prey PSO algorithm is presented, which is using density function to initialize clustercentre.
为解决此问题，提出一种基于捕食-被捕食的粒子群优化模糊聚类算法且聚类中心采用密度函数初始化。

In this paper, clustercentre and the distance from point to the clustercentre was defined, and a dynamic analysis method for plane point set was put forword.
本文定义了聚类中心以及点到聚类中心的距离，提出了一种平面点集的动态聚类分析方法。

The Spitzer observations also helped confirm a massive galaxy at the centre of the cluster was forming stars at an impressive rate.
