discrete mathematics with graph theory 2nd edition pdf

Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph. Describe the concept of relationships Association--used to describe the relationship between a point and an edge, which simp

is slightly different, for the Mij value, like the following three kinds of situations:(1) VI is not associated with EJ, mij = 0;(2) VI is the starting point of EI, mij = 1;(3) VI is the focus of EI, mij=-1;(4)Adjacency matrix of a directed graph: for AIJ, the number of edges that represent VI->VJ (direct connectivity)There is a very important theorem about the adjacency matrix of a graph:Set A is the adjacency matrix of directed
