Dynamic Cycle Detection

Abstract

This paper presents algorithms for maintaining a directed acyclic graph in a dynamically changing environment. In such an environment, nodes and edges are occasionally added and deleted. The underlying idea is to perform a depth first search after each edge addition. Heuristics are presented to make fewer and relatively short searches. The problem of… (More)
