GRAPH THEORY WITH APPLICATIONS
www.iro.umontreal.caof figure 1.3 are. Much of graph theory is concerned with the study of simple graphs. We use the symbols v(G) and e(G) to denote the numbers of vertices and edges in graph G. Throughout the book the letter G denotes a graph. Moreover, when just one graph is under discussion, we usually denote this graph by G.
Graph Theory - Tutorialspoint
www.tutorialspoint.comGraph Theory 3 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, etc.
