Abstract

In the scope of distributed constraint reasoning, the main algorithms presented so far have a feature in common: the addition of links between previously unrelated agents, before or during search. Our work presents a new search procedure for finding a solution in a distributed constraint satisfaction problem. This algorithm makes use of some of the good properties of centralized dynamic backtracking. It is sound, complete and allows a high level of asynchronism by sidestepping the unnecessary addition of links.
