Convergence Efficiency of a Class of Improved Vicsek Model

For the problem of the low convergence efficiency of Vicsek model,a new rule is proposed to parallel the motion directions of all individuals quickly based on the research of network topology relationships of the groups.Unlike the motion direction renewal equation of Vicsek model and its linear one,the rule forces an individual moving toward the middle of two neighbors' motion directions with the maximum deviation at next time.On the premise that initial position distribution of the group network is topology connectivity,a contrast study of the convergence efficiency of the improved model,Vicsek model and its linear model is done on NetLogo simulation platform.Simulation results show that the process of paralleling the directions is accelerated obviously and the convergence efficiency of dynamic swarming behavior is improved efficiently by the improved model under the control of the new rule.
