A Parallel Algorithm for Computing Minimum Spanning Trees
We present a simple and implementable algorithm that computes a minimum spanning tree of an undirected weighted graph G = (V; E) of n = jV j vertices and m = jEj edges on an EREW PRAM in O(log 3=2 n) time using n+m processors. This represents a substantial improvement in the running time over the previous results for this problem using at the same time the weakest of the PRAM models. It also implies the existence of algorithms having the same complexity bounds for the EREW PRAM, for connectivity, ear decomposition, biconnectivity, strong orientation, st-numbering and Euler tours problems.

Title : A Parallel Algorithm for Computing Minimum Spanning Trees
Abstract : We present a simple and implementable algorithm that computes a minimum spanning tree of an undirected weighted graph G = (V; E) of n = jV j vertices and m = jEj edges on an EREW PRAM in O(log 3=2 n) time using n+m processors. This represents a substantial improvement in the running time over the previous results for this problem using at the same time the weakest of the PRAM models. It also implies the existence of algorithms having the same complexity bounds for the EREW PRAM, for connectivity, ear decomposition, biconnectivity, strong orientation, st-numbering and Euler tours problems. List of Symbols O() Capital Oh, slanted (math) O Capital Oh 0 zero l ell 1 one o() Lowercase oh, slanted (math) o lowercase oh ff greek alpha 1 Introduction This paper describes a new parallel algorithm for computing the minimum spanning tree (MST) of a graph in the EREW PRAM model of parallel computation, the weakest of the PRAM models.
