WebFormally, a graph is an ordered pair G = (V, E), where V is a set of nodes. E is a set of edges. G is defined as an ordered pair so it's clear which set is the nodes and which is … Web1 From the source of all knowledge a graph is an ordered pair G = (V, E) comprising a set V of vertices or nodes together with a set E of edges or lines, which are 2-element subsets of V Why must it be an ordered pair? It seems irrelevant if you mention V or E first. Must V come first since E is made up of V? graph-theory definition Share Cite

Webordered pairs of elements of V called edges (or arcs). The vertex a is called the initial vertex of the edge (a, b), and the vertex b is called the terminal vertex of this edge. 9.3 pg. 596 # 1 Represent each of these relations on f1;2;3gwith a matrix (with the elements of this set listed in increasing order). Webof ordered pairs. If e = (x,y), the vertex x is called origin, source or initial point of the edge e, and y is called the terminus, terminating vertex or terminal point. b d c a Figure 7.3.
