Trends and Questions in Open Multi-agent Systems

This chapter presents a survey of recent trends in the analysis of open multi-agent systemsMulti-agent system, where the set of agents is time-varying. We first introduce the notions of arrivals, departuresDeparture and arrival, and replacementsReplacement of agents in the context of multi-agent systemsMulti-agent system, including several approaches for the modeling and time evolution. We then provide alternative definitions for concepts that must be adapted to conduct analyses in the open context, such as stability and convergenceConvergence. We also consider some aspects of open systems that must be taken into account in the design of algorithms. Finally, some applications are presented to illustrate the current importance of open multi-agent systemsOpen multi-agent system as well as future perspectives in this framework.
