In 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 symmetrically, and directed graphs, wh… 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 …

WebAug 3, 2024 · Source Graph theory – Wikipedia. Cyclic Graph and loops: Loops: In graph theory, a loop or a self-loop is a node that connects a vertex to itself. Cyclic and Acyclic graphs: Whenever in a graph, a few vertices are attached in a closed chain of relations, then the graph is said to have a cycle. Webk-Vertex-Colorings If G = (V, E) is a graph, a k-vertex-coloring of G is a way of assigning colors to the nodes of G, using at most k colors, so that no two nodes of the same color …
WebGraph theory is the study of mathematical objects known as graphs, which consist of vertices (or nodes) connected by edges.

Euler’s formula tells us that if G is a connected planar simple graph with E edges and V vertices, then the number of regions, R, in a planar representation of G is: R = E − V + 2 or R − E + V = 2. Let’s illustrate Euler’s formula with our example.
