We give a linear-time algorithm for single-source shortest paths in planar graphs with nonnegative edge-lengths. Our algorithm also yields a linear-time algorithm for maximum flow in a planar graph with the source and sink on the same face. For the case where negative edge-lengths are allowed, we gi

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

Shortest path computation is required by a large number of applications such as VLSI, transportation, and communication networks. These applications, which are often very complex and have sparse networks, generally use parallel labeling shortest path algorithms. Such algorithms, when implemented on

We give a randomized parallel algorithm for computing single-source shortest paths in weighted digraphs. We show that the exact shortest-path problem can be efficiently reduced to solving a series of approximate shortest-path subproblems. Our algorithm for the approximate shortest-path problem is ba
