Abstract

This paper presents a BDD-based implicit algorithm to compute all maximal strongly connected components of directed graphs. The algorithm iteratively applies reachability analysis and sequentially identifies SCCs. Experiments suggest that the algorithm dramatically outperforms the only existing implicit method which must compute the transitive closure of the adjacency-matrix of the graphs.
