The '''Dijkstra-Scholten Algorithm''' is an [[algorithm]] for detecting [[Termination analysis|termination]] in a [[distributed system]]. The algorithm was proposed by Dijkstra and Scholten in [[1980]].
First, let us consider the case of a simple process graph which is a tree. A distributed computation which is tree-structured is not uncommon. Such a process graph may arise when the computation is strictly divide-and-conquer type. A node starts the computation and divides the problem in two (or more, usually a multiple of 2) roughly equal parts and distribute those parts to other processors. This process continues recursively until the problems are of sufficiently small size to solve in a single processor.
