We present a simple and implementable algorithm that computes a minimum spanning tree of an undirected weighted graph \(G=(V, E)\) of \(n=|V|\) vertices and \(m=|E|\) edges on an EREW PRAM in \(O\left(\log ^{3 / 2} n\right)\) time using \(n+m\) processors. This represents a substantial improvement i
This paper presents results which improve the e ciency of parallel algorithms for computing the minimum spanning trees. For an input graph with n vertices and m edges our EREW PRAM algorithm runs in O(log n) time with O((m+n) log n) operations. Our CRCW PRAM algorithm runs in O(log n) time with O((m
We describe an efficient algorithm for maintaining a minimum spanning tree (MST) in a graph subject to a sequence of edge weight modifications. The sequence of minimum spanning trees is computed offline, after the sequence of modifications is known. The algorithm takes time \(O(k \log n)\) for a seq
