Coordination in utility managed multi-agent groups

摘要

A two stage approach to co-ordination in a multi-agent society is presented. The first stage involves agents learning to co-ordinate their activities based on local and global utility - the latter being assigned by an Environment Service Node. Each agent aims to maximise its local utility over a single-step or finite horizon, subject to reinforcements being received from the ESN. An agent may reveal all or partial state to the ESN, and docs so through specialised function operators. Groups are formed by agents trying to identify partners which enable them to achieve a higher local utility. Subsequent interactions with the group are structured and managed via Grouploq- an approach for supporting interactions between agents within a community. An example based on resource sharing within a Computational Grid is used to illustrate how the two approaches may be combined.
