WebEnumeration of spanning trees of an undirected graph is one of the graph problems that has received much attention in the literature. In this paper a new enumeration algorithm based on the idea of contractions of the graph is presented. The worst-case time complexity of the algorithm isO(n+m+nt) wheren is the number of vertices,m the number of edges, andt the … Webproblem, based on Gabow’s scaling algorithm for SSSP [4]. This algorithm makes use of a simpler data structure for its priority queue, which naturally exposes available much of the parallelism in the problem. Furthermore, the only assumption this parallel Gabow algorithm uses is that all edge weights in the graph are in-
