are never any forward or cross edges.
Step by step
Solved in 3 steps with 1 images
- Prove that when doing depth-first search on undirected graphs there are never any forward or cross edges.Determine whether or not the loop-free undirected graphs with the following adjacency matrices are isomorphic. Explain why.Prove that in any simple graph G (i.e. no multiple edges, no loops) there exist two distinct vertices with the same degrees.
- Prove that in each component of the context of any graph, the number of vertices of an odd degree is always even.Prove that "If a connected planar simple graph has e edges and v vertices with v ≥ 3 and no circuits of length three, then e ≤ 2v − 4."Say that a graph G has a path of length three if there exist distinct vertices u, v, w, t with edges (u, v), (v, w), (w, t). Show that a graph G with 99 vertices and no path of length three has at most 99 edges.
- List all the non-isomorphic simple graphs with 5vertices and 4 edges.Prove that in a breadth-first search on a undirected graph G, every edge iseither a tree edge or a cross edge, where x is neither an ancestor nor descendant of y, in cross edge (x, y).In an undirected graph G, must every cut edge e be an edge in a depth-first search tree of G, or can e be a back edge? Give a proof or a counterexample. (Any edge whose removal disconnects the graph is called a cut edge.)
