A Randomized Parallel Algorithm for Single-Source Shortest Paths
نویسندگان
چکیده
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 based on the technique used by Ullman and Yannakakis in a parallel algorithm for breadth-first search. Q 1997 Academic Press

Parallel Single-Source Shortest Paths
We designed and implemented a parallel algorithm for solving the single-source shortest paths (SSSP) problem for graphs with nonnegative edge weights, based on Gabow’s scaling algorithm for SSSP. This parallel Gabow algorithm attains a theoretical parallelism of Ω(E/(V lg∆ lgE/D)) in the worst case and Ω(E/(D lgV/D lgE/D lgDelta)with high probability on a random graph. In practice this algorith...
متن کاملConversion of Network Problem with Transfer Nodes, and Condition of Supplying the Demand of any Sink from the Particular Source to the Transportation Problem
In this article we present an algorithm for converting a network problem with several sources and several sinks including several transfer nodes and condition of supplying the demand of any sink from a particular source to the transportation problem. Towards this end, and considering the very special structure of transportation algorithm, after implementing the shortest path algorithm or ...

The Parallel Boost Graph Library (Parallel BGL) is a library of graph algorithms and data structures for distributed-memory computation on large graphs. Developed with the Generic Programming paradigm, the Parallel BGL is highly customizable, supporting various graph data structures, arbitrary vertex and edge properties, and different communication media. In this paper, we describe the implemen...
متن کاملEfficient Parallel Algorithms for Planar st-Graphs1
Planar st-graphs find applications in a number of areas. In this paper we present efficient parallel algorithms for solving several fundamental problems on planar st-graphs. The problems we consider include all-pairs shortest paths in weighted planar st-graphs, single-source shortest paths in weighted planar layered digraphs (which can be reduced to single-source shortest paths in certain speci...
متن کاملAll Pairs Shortest Paths: Randomization and Replacement
We present a survey of results in the field of graph algorithms. We begin with an All Pairs Shortest Path algorithm with some constraints that runs in O(n) by Peres. We continue with a Replacement Paths algorithm by Williams and conclude with a smoothed analysis of a Single Source Shortest Paths algorithm by Banderier. Each of these problems has connections to randomization in graph algorithms.
