Peng, Liqian Zhao, Yang Tian, Baomei Zhang, Jue Wang, Bing-Hong Zhang, Hai-Tao Zhou, Tao 2009-02-27 In recent years, many efforts have been addressed on collision avoidance of collectively moving agents. In this paper, we propose a modified version of the Vicsek model with adaptive speed, which can guarantee the absence of collisions. However, this strategy leads to an aggregated state with slowly moving agents. We therefore further add a certain repulsion, which results in both faster consensus and longer safe distance among agents, and thus provides a powerful mechanism for collective motions in biological and technological multiagent systems. application/pdf https://folia.unifr.ch/global/documents/301085 https://folia.unifr.ch/documents/301085/files/zhou_csd.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevE.79.026113 info:eu-repo/semantics/openAccess License undefined Physical Review E. - 2009, vol. 79, no. 2, p. 026113 aggregation multi-agent systems phase transformations info:eu-repo/classification/udc/53 Consensus of self-driven agents with avoidance of collisions http://purl.org/coar/resource_type/c_6501
