The minimum spanning tree problem

Possible multiplicity If there are n vertices in the graph, then each spanning tree has n − 1 edges. There may be several minimum spanning trees of the same weight; in particular, if all the edge weights of a given graph are the same, then every spanning tree of that graph is minimum. Uniqueness If each edge has a … See more A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the … See more Alan M.
