The Influence of Hypocrite on Cluster Motion Under Vicsek Model

Vicsek model is a fundamental model to research a multi-agent system, the evolution of cluster behavior is presented intuitively under this model. This article takes cluster dynamics as the research background, the movement of agents in the group is simplified into arrows, and we see the agents who choose the same forward direction in 36 directions as the same strategies chosen. This article also considers that everyone in a group is like to change his strategy, because of the others around him. And then, we get the graph from disorder to order. Furthermore, we consider hypocrite in the group. Its existence reduces the cooperation rate continuously. We analyze earnings and reputation values changing in the group.
