7.5 (i) Prove that, if G is a bipartite graph with an odd number of vertices, then G is non-Hamiltonian. (ii) Deduce that the graph in Fig. 7.7 is non-Hamiltonian. Fig. 7.7 (iii) Show that, if n is odd, it is not possible for a knight to visit all the squares of an n chessboard exactly once by knight's moves and return to its starting point.

Prove or disprove the following: For any (non-directed) graph, the number of odd-degree nodes is even. In a minimally connected graph of n>2 nodes with exactly k nodes of degree 1 , 1<k<n. I.e., you cannot have a minimally connected graph with 1 node of degree 1 or n nodes of degree 1.

An odd graph is one where each vertex is of odd degree. Show that a graph is odd if and only if a(X) = |x|(mod2) for each subset X of V.

Assume that the graphs in this problem are simple undirected graphs A. The minimum possible vertex degree in a connected undirected graph of N vertices is: B. The maximum possible vertex degree in a connected undirected graph of N vertices is: C. The minimum possible vertex degree in a connected undirected graph of N vertices with all vertex degree being equal is: D. The number of edges in a completely connected undirected graph of N vertices is: E. Minimum possible...

6: A: Draw a graph with 5 vertices and the requisite number of edges to show that if four of the vertices have degree 2, it would be impossible for the 5 vertex to have degree 1. Repetition of edges is not permitted. (There may not be two different bridges connecting the same pair of vertices.) B: Draw a graph with 4 vertices and determine the largest number of edges the graph can have, assuming repetition of edges...
