An outerplanar graph is a planar graph that can be imbedded in the plane in such a way that all vertices lie on the exterior face. An outerplanar graph is maximal if no edge can be added to the graph without violating the outerplanarity. In this paper, an optimal parallel algorithm is proposed on th

We present a parallel randomized algorithm running on a CRCW PRAM, to determine whether two planar graphs are isomorphic, and if so to find the isomorphism. We assume that we have a tree of separators for each planar graph ลฝ ลฝ 2 . 1 q โ which can be computed by known algorithms in O log n time with
We present an optimal parallel algorithm for the single-source shortest path problem for permutation graphs. The algorithm runs in \(O(\log n)\) time using \(O(n / \log n)\) processors on an EREW PRAM. As an application, we show that a minimum connected dominating set in a permutation graph can be f
