WebSpanning tree. A spanning tree is a sub-graph of an undirected connected graph, which includes all the vertices of the graph with a minimum possible number of edges. If a vertex is missed, then it is not a spanning tree. The edges may or may not have weights assigned to them. The total number of spanning trees with n vertices that can be ... WebFigure 4.18 shows an example in which Prim's MST algorithm selects the vertex v 0 as the starting vertex. In fact, an MST can be built from any starting vertex. Moreover, an MST is not necessarily unique. For example, if the edge (v 7, v 8) replaces the edge (v 3, v 8), as shown in Figure 4.18, the new set of edges still forms an MST.
