_{Complete graph definition. Determining whether a graph can be colored with 2 colors is in P, but with 3 colors is NP-complete, even when restricted to planar graphs. Determining if a graph is a cycle or is bipartite is very easy (in L ), but finding a maximum bipartite or a maximum cycle subgraph is NP-complete. }

In the mathematical field of graph theory, a bipartite graph (or bigraph) is a graph whose vertices can be divided into two disjoint and independent sets and , that is, every edge connects a vertex in to one in . Vertex sets and are usually called the parts of the graph. Equivalently, a bipartite graph is a graph ... We observe that a complete graph with n vertices is n − 1-regular, and has.

A complete bipartite graph is a graph ...A clique is a subset of vertices of an undirected graph G such that every two distinct vertices in the clique are adjacent; that is, its induced subgraph is complete. Cliques are one of the basic concepts of graph theory and are used in many other mathematical problems and constructions on graphs. The task of finding whether there is a clique ...If we add all possible edges, then the resulting graph is called complete. That is, a graph is complete if every pair of vertices is connected by an edge. Since a graph is determined completely by which vertices are adjacent to which other vertices, there is only one complete graph with a given number of vertices. We give these a special name ...

It can also be found by finding the maximum value of eccentricity from all the vertices. Diameter: 3. BC → CF → FG. Here the eccentricity of the vertex B is 3 since (B,G) = 3.

Characteristics of Complete Graph:The graph connectivity is the measure of the robustness of the graph as a network. In a connected graph, if any of the vertices are removed, the graph gets disconnected. Then the graph is called a vertex-connected graph. On the other hand, when an edge is removed, the graph becomes disconnected. It is known as an edge-connected graph. graph. (data structure) Definition: A set of items connected by edges.
