题目：Coordination of multi-agent systems: the role of global information and the influence of antagonistic interactions

  摘要：Achieving coordination is a fundamental problem in the study of multi-agent systems. A basic understanding is that sufficient connectivity of the network will lead to an agreement of dispersed states. In the commonly considered networks, the exchanged information is assumed to be purely local and the relationships between different agents are considered to be cooperative. However, in certain, or even most of network setting, there are also global information that can be used for agreement seeking and antagonistic interactions that may affect the state evolution. In this talk, we try to understand what is the role of global information (specifically, “compass”) in the classical network model and how antagonistic interactions will influence state evolution of the network. In particular, we validate that the global information is useful for agreement seeking of multi-agent systems in the sense of relaxing the fundamental convexity condition of the classical social network model and accelerating the convergence speed. In addition, we reveal that both cooperative and antagonistic interactions contribute to state convergence of cooperative-antagonistic network and strong connectivity, instead of quasi-strong connectivity, is critical.
