Approximation algorithms for the optimal p-source communication spanning tree
The computational complexity and the approximation algorithms of the optimal p-source communication spanning tree (p-OCT) problem were investigated. Let G be an undirected graph with nonnegative edge lengths. Given p vertices as sources and all vertices as destinations, and also given arbitrary requirements between sources and destinations, we investigated the problem how to construct a spannin...
متن کاملCommunication-optimal Parallel Minimum Spanning Tree Algorithms
Lower and upper bounds for nding a minimum spanning tree (MST) in a weighted undirected graph on the BSP model are presented. We provide the rst non-trivial lower bounds on the communication volume required to solve the MST problem. Let p denote the number of processors, n the number of nodes of the input graph, and m the number of edges of the input graph. We show that in the worst case, a tot...
متن کاملApproximation Algorithms for Some Optimum Communication Spanning Tree Problems
Let G = (V; E; w) be an undirected graph with nonnegative edge length function w and nonnegative vertex weight function r. The optimal product-requirement communication spanning tree (PROCT) problem is to nd a spanning tree T minimizing ∑ u; v∈ V r(u)r(v)dT (u; v), where dT (u; v) is the length of the path between u and v on T . The optimal sum-requirement communication spanning tree (SROCT) pr...
متن کاملOptimal Communication algorithms on Star Graphs Using Spanning Tree Constructions
In this paper we consider three fundamental communicationproblems on the star interconnection network: the problem of simultaneous broadcasting of the same message from every node to all other nodes, or multinode broadcasting, the problem of a single node sending distinct messages to each one of the other nodes, or single node scattering, and nally the problem of each node sending distinct mess...
متن کاملOn Optimal Solutions for the Optimal Communication Spanning Tree Problem
This paper presents an experimental investigation into the properties of the optimal communication spanning tree (OCST) problem. The OCST problem seeks a spanning tree that connects all the nodes and satisfies their communication requirements at a minimum total cost. The paper compares the properties of random trees to the properties of the best solutions for the OCST problem that are found usi...
