In this article, we present an efficient computational implementation of an algorithm for finding the K shortest simple paths connecting a pair of vertices in an undirected graph with n vertices, m arcs, and nonnegative arc lengths. A minimal number of intermediate paths is formed based on the metho
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
