Graph theory

In terms of graph theory, in any graph the sum of all the vertex-degrees is an even number - in fact, twice the number of edges additionally, we can tell that in any graph the number of odd degree vertices is even 2 eulerian graphs. Topics in algebraic graph theory the rapidly expanding area of algebraic graph theory uses two different branches of algebra to explore various aspects of graph theory: linear algebra (for spectral theory) and. Graph theory i about the tutorial this tutorial offers a brief introduction to the fundamentals of graph theory written in a reader-friendly style, it covers the types of graphs, their properties, trees, graph traversability, and the concepts of coverings, coloring, and matching. In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related the objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called an arc or line.

Graph theory is the study of mathematical objects known as graphs, which consist of vertices (or nodes) connected by edges (in the figure below, the vertices are the numbered circles, and the edges join the vertices. Graph theory represents one of the most important and interesting areas in computer science but at the same time it’s one of the most misunderstood (at least it was to me) understanding, using and thinking in graphs makes us better programmers.

In this graph databases for beginners blog series, i’ll take you through the basics of graph technology assuming you have little (or no) background in the space in past weeks, we’ve tackled why graph technology is the future, why connected data matters, the basics (and pitfalls) of data modeling, why a database query language matters and the differences between imperative and declarative. D3 graph theory 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, nodes, or points which are connected by edges, arcs, or lines. Graph theory po-shen loh 24 june 2008 at first, graph theory may seem to be an ad hoc subject, and in fact the elementary results have proofs of that nature.

Graph theory, branch of mathematics concerned with networks of points connected by lines the subject of graph theory had its beginnings in recreational math problems (see number game), but it has grown into a significant area of mathematical research, with applications in chemistry, operations research, social sciences, and computer science. English: graph theory is the branch of mathematics that examines the properties of mathematical graphs see glossary of graph theory for common terms and.
