Jenna quit to be near her ailing mother. /Font << Theorem 3.1 (Euler) A connected graph G is an Euler graph if and only if all vertices of G are of even degree. How does this work?

Problem 3 Show that Petersen graph is not Hamil-tonian. Note that only one vertex with odd degree is not possible in an undirected graph (sum of all degrees is always even in an undirected graph). that any hamiltonian digraph must be strongly connected; any hamiltonian undi- rected graph must contains no cut-vertex. Yes. We then choose the least integer \(i\) for which there is an edge incident with \(x_i\) that has not already been traversed. \NYnh|NdaNa\Fo7IF Suppose the theorem fails and let \(n\) be the least positive integer for which there exists a graph \(\textbf{G}\) on \(n\) vertices so that each vertex in \(\textbf{G}\) has at least \(n/2\) neighbors, yet there is no hamiltonian cycle in \(\textbf{G}\).

Bannai [1] has shown that G (n, k) is Hamiltonian when n and k are relatively prime and G (n, k) is not isomorphic to G (n, 2) with n---=-5 (mod 6). >> Such a sequence of vertices is called a hamiltonian cycle. 34 0 obj /ProcSet [/PDF /Text /ImageB] /Widths [750 278 278 355 556 556 889 667 191 333 /ProcSet [/PDF /Text /ImageB] The first graph shown in Figure 5.16 both eulerian and hamiltonian.
