WebDegree: The degree of a vertex in a graph is the number of edges that are incident to it, i.e., the number of edges that connect to that vertex. The degree of a vertex is denoted by deg(v). For example, in a simple graph with four vertices and five edges, if vertex v has three edges connecting to it, then deg(v) = 3. WebDescribing graphs. A line between the names of two people means that they know each other. If there's no line between two names, then the people do not know each other. The relationship "know each other" goes both …

His attempts & eventual solution to the famous Königsberg bridge problem … WebIn mathematics, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects.A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called links or lines).A distinction is made between undirected graphs, where edges link two vertices …
WebBasic Terms used in Graph Theory. Graph: An abstract mathematical structure, to model pairwise relations between discrete objects. A graph G = ( V , E ) consists of a finite set V ( set of vertices or nodes ) and a set E (set of edges ) of 2-subsets of V. Each edge is a relation ( adjacency ) between two vertices. Web1. Discuss two (2) applications of Graph Theory in real life.2. Give two definitions of basic terms, with example illustration for each, that you learned in the study of Graph Theory3.
