Distributed Truth Maintenance

David Murray Bridgeland, Michael N. Huhns

In this paper we define the concept of logical consistency of belief among a group of computational agents that are able to reason nonmonotonically. We then provide an algorithm for truth maintenance that guarantees local consistency for each agent and global consistency for data shared by the agents. Furthermore, we show the algorithm to be complete, in the sense that if a consistent state exists, the algorithm will either find it or report failure. The algorithm has been implemented in the RAD distributed expert system shell.
