AbstractThis paper presents results which improve the efficiency 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+n)log log n) operations. We also show that for dense graphs we can achieve O(log n) time with O(n2) operations on the EREW PRAM. © 2002 Published by Elsevier Science B.V.
