A theory to devise dependable cooperative encounters
Abstract
In this paper, we investigate the question of how to characterize " fault tolerance " in cooperative agents. It is generally admitted that cooperating agents can achieve tasks that they could not achieve without cooperation. Nevertheless, cooperating agents can have " Achilles' heels " , a cooperative encounter can eventually fail to achieve its tasks because of the collapse of a single agent. The contribution of this paper is the study of how cooperating agents are affected by dependability issues. Specifically, our objectives are twofold: to formally define the concepts of dependability in cooperative encounters, and to analyze the computational complexity of devising dependable cooperative encounters.
