Complete Graph In Graph Theory

A complete graph is a simple undirected graph in which every pair of distinct vertices is connected by a unique edge. Learn about its properties, notation, geometry, topology, and applications in graph theory.

A complete graph Kn on n vertices is a graph with all possible edges between them. Learn the definition, properties and examples of complete graphs and other important graph classes in this lecture notes by Prof. Dr. Maria Axenovich.

Here are two methods for identifying a complete graph Check the degree of each vertex In a complete graph with n vertices, every vertex has degree n-1. So, if you can determine that every vertex in the graph has degree n-1, then the graph is a complete graph. Check the number of edges A complete graph with n vertices has nn-12 edges.

The complete graphs are distance-regular, geometric, and dominating unique.. is the cycle graph, as well as the odd graph Skiena 1990, p. 162. is the tetrahedral graph, as well as the wheel graph, and is also a planar graph. is nonplanar, and is sometimes known as the pentatope graph or Kuratowski graph. Conway and Gordon 1983 proved that every embedding of is intrinsically linked with at

Learn the definition, properties, and applications of complete graphs, a type of graph where every vertex is adjacent to every other vertex. Explore the special cases, computational complexity, and graph coloring of complete graphs.

5 Graph Theory Informally, a graph is a bunch of dots and lines where the lines connect some pairs of dots. An example is shown in Figure 5.1. Figure 5.2 The complete graph on 5 nodes, K5. Figure 5.3 The empty graph with 5 nodes. The n-node graph containing n 1edges in sequence is known as the line graph Ln.

A complete graph of order n n is denoted by K n K n. The figure shows a complete graph of order 5 5. Draw some complete graphs of your own and observe the number of edges. You might have observed that number of edges in a complete graph is n n 1 2 n n 1 2. This is the maximum achievable size for a graph of order n n as you learnt in

There are two special types of graphs which play a central role in graph theory, they are the complete graphs and the complete bipartite graphs. A complete graph is a simple graph whose vertices are pairwise adjacent. The complete graph with n vertices is denoted Kn. K 1 K 2 K 3 K 4 K 5 Before we can talk about complete bipartite graphs, we

Complete graphs are used in optimization problems, such as the traveling salesman problem, where the goal is to find the shortest route that visits each city vertex exactly once. How many edges are in a complete graph? In a complete graph with 92 n 92 vertices, there are exactly 92 92fracnn-12 92 edges because each vertex is connected to

Definition Complete Graph. A simple graph in which every vertex is adjacent to every other vertex, is called a complete graph. If this graph has 92n92 vertices, then it is denoted by 92K_n92. The notation 92K_n92 for a complete graph on 92n92 vertices comes from the name of Kazimierz Kuratowski, a Polish mathematician who lived from 1896-1980.
