Collective Motion of the Couzin Model with Randomly Valued Time Delays

Collective motion is a common phenomenum in nature, and needs to be well-understood. In this paper, we try to understand this phenomenum by using the generalized Couzin model with heterogenous time delays. Simulation is carried out by using LAMMPS secondary development.

Description
Summary:Collective motion is a common phenomenum in nature, and needs to be well-understood. In this paper, we try to understand this phenomenum by using the generalized Couzin model with heterogenous time delays. Simulation is carried out by using LAMMPS secondary development. It is found that when the homogeneous delay time increases, patterns of the collective motion change from highly parallel to vortex motion. While for heterogenous time delays, the individuals with short delays tend to distribute at the front part of the cluster when the delays are approximately normally distributed. If the cluster is divided into two sub-clusters, the distribution of individuals with short delays changes from favouring the front of the cluster to back, as the delay difference between two sub-clusters increases.
