摘要:In this paper, we consider the past temporal operators in multi-agent systems. Three temporal operators po (previous), p♦ (once), and p♥ (has-always-been) are defined. These past temporal operators can be used for reasoning about events that happen along a single run r (in the past) in the system R, where R models the possible behaviors of the system being modeled. Some important properties of agents (expressed by the formulas : Ki => poK), Ki => p♦Kj, and Ki => p♥Kj) are characterized.
