Discrete math graphs. The complete graph is also the complete n partite graph. In contrast to real numbers that have the property of varying smoothly the objects studied in discrete mathematics such as integers graphs and statements in logic do not vary smoothly in this way but have distinct separated values. Since then it has blossomed in to a powerful tool used in nearly every branch of science and is currently an active area of mathematics research. Discrete mathematics graph theory simple graphs miscellaneous graphs simple graph a simple graph also called a strict graph tutte 1998 p.

2 is an unweighted undirected graph containing no graph loops or multiple edges gibbons 1985 p. What is a graph. This article is contributed by chirag manwani. A cycle cnfor n 3consists of nvertices v1 v2 vn and edges v1 v2 v2 v3 vn 1 vn vn v1.

A complete graph on n vertices denoted by kn is the simple graph that contains exactly one e dge between each pair of distinct vertices. Graph theory is a relatively new area of mathematics first studied by the super famous mathematician leonhard euler in 1735. Discrete mathematics therefore excludes topics in continuous mathematics such as calculus or euclidean geometry. Graphs wikipedia discrete mathematics and its applications by kenneth h rosen.

Cs 441 discrete mathematics for cs m. The study of graphs or graph theory is an important part of a number of disciplines in the fields of mathematics engineering and computer science. A graph in which there is a path of edges between every pair of vertices in the graph. A complete graph is a graph in which each pair of graph vertices is connected by an edge the complete graph with graph vertices is denoted and has the triangular numbers undirected edges where is a binomial coefficient in older literature complete graphs are sometimes called universal graphs.

Some of those are as follows. For example if the vertices represent people at a party and there is an edge between two people if they shake hands then this graph is undirected because any person a can shake hands with a person b only if b also shakes hands with a. Also called an empty graph a null graph is a graph in which there are no edges between any of its vertices. Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.

A graph is a set of points called nodes or vertices which are interconnected by a set of lines called edges. The edges may be directed or undirected.
