Web4 Graph Theory III Definition. A tree T = (V,E) is a spanning tree for a graph G = (V0,E0) if V = V0 and E ⊆ E0. The following figure shows a spanning tree T inside of a graph G. = T Spanning trees are interesting because they connect all the nodes of a graph using the smallest possible number of edges. WebGraph Theory Fundamentals - A graph is a diagram of points and lines connected to the points. It has at least one line joining a set of two vertices with no vertex connecting itself. The concept of graphs in graph theory stands up on some basic terms such as point, line, vertex, edge, degree of vertices, properties of graphs,
