Modeling cooperation by observation in agent team

Supporting proactive communication among agents in multi-agent teamwork is crucial. In this paper, we focus on how to represent observability, and how to include it into the basic reasoning for proactive communication. We show how agents can use observation of the environment and of teammates' actions to estimate the teammates' beliefs without generating unnecessary messages. The experiment shows that agents can anticipate information needs among the team members and proactively communicate the information, reducing the total volume of communication.
