Dynamic Evolution Process of Social Network Community Structure Based on Aggregation-Division Model

In this paper, an Aggregation-Division Model (ADM) is proposed to simulate the clustering characteristics of nodes in cyberspace and to describe the dynamic evolution process of the community system structure. Based on Cluster-Cluster Aggregation (CCA) model, using the random walk and collision of discrete single particle to simulate the communication and relationship establishment of nodes in social networks to produce stochastic process of larger clusters. At the same time, this paper also mentions that under the effect of internal and external environment factors, the monomer results in the instability of community structure and then lead to the whole community gradually split into a small structure. Meanwhile, to display and illustrate the dynamic evolution process of community structure by visual programming.
