WebMar 29, 2024 · Graph and its representations. 1. A finite set of vertices also called as nodes. 2. A finite set of ordered pair of the form (u, v) called as edge. The pair is ordered because (u, v) is not the same as (v, u) in case of a directed graph (di-graph). The pair of the form (u, v) indicates that there is an edge from vertex u to vertex v. WebIn a graph, if an edge is drawn from vertex to itself, it is called a loop. Example 1. In the above graph, V is a vertex for which it has an edge (V, V) forming a loop. Example 2. In this graph, there are two loops which are formed at vertex a, and vertex b. Degree of Vertex. It is the number of vertices adjacent to a vertex V. Notation − deg ... smart cat bed

WebThis means that there can be no edges connecting two vertices in the same set. In the graph shown, the edge BF connects two vertices in the same set, which means that the graph is not bipartite. To make the graph bipartite, the edge BF must be removed. Removing the edge BF will divide the graph into two distinct sets, A and B.
