Webb23 apr. 2024 · Adjacency matrices of directed graphs only cover one side of the diagonal line, since directed graphs have edges that go in only one direction. An adjacency matrix can be “weighted”, which basically means each edge has an associated value attached to it, so instead of 1s, the value is put in the respective matrix coordinate. Webb1 nov. 2024 · Suppose a simple graph G on n ≥ 2 vertices has at least ( n − 1) ( n − 2) 2 + 1 edges. Prove that G is connected. Exercise 5.E. 7.2 Suppose a general graph G has exactly two odd-degree vertices, v and w. Let G ′ be the graph created by adding an edge joining v to w. Prove that G ′ is connected if and only if G is connected. Exercise 5.E. 7.3 Webb1 feb. 2024 · If an edge is directed from one vertex (node) to another, a graph is called a directed graph. An directed edge is called an arc. Though graphs may look very theoretical, many practical problems can be represented by graphs.
