Chapter , Problem 44E(choose chapter or problem)
Find a minimum spanning tree of each of these graphs where the degree of each vertex in the spanning tree does not exceed 2. Let G = (V, E) be a directed graph and let r be a vertex in G. An arborescence of G rooted at r is a subgraph T = (V, F) of G such that the underlying undirected graph of T is a spanning tree of the underlying undirected graph of G and for every vertex v ? V there is a path from r to v in T (with directions taken into account).
