Recently,swarming behavior for multi-agent systems has been a hot research topic in the field of complex network.In this paper,starting from the two factors of the intrinsic dynamics of agent and the topology structure,the development status of swarming behavior in the multi-agent system is summarized,and then the corresponding distributed protocol,convergent speed and the condition of implementation are introduced and analyzed.Finally,combined with the current research status,the future research directions of swarming behavior are discussed.
