In mathematics, graph theory is that the study of graphs, which are mathematical structures accustomed model pair wise relations between objects. A graph during this context is formed of vertices (also called nodes or points) which are connected by edges (also called links or lines). A distinction is molded between undirected graphs, where edges interface two vertices symmetrically, and facilitated graphs, where edges interface two vertices disproportionately; see graphs(discrete arithmetic) for more point by point definitions and for other varieties inside the assortments of graph that are commonly considered.. Graphs are one in every of the prime objects of study in discrete mathematics.

Other topics

Graphs is accustomed model many sorts of relations and processes in physical, biological, social and knowledge systems. Many practical problems is represented by graphs.

Computer science

In engineering, graphs are used to represent networks of communication, data organization, computational devices, the flow of computation, etc. Graph theory is employed for the study of algorithms. for instance

• Kruskal's Algorithm

• Prim's Algorithm

• Dijkstra's Algorithm

Electrical Engineering

The concepts of graph hypothesis are utilized broadly in planning circuit associations. the kinds or organization of associations are named as topologies. some cases for topologies are star, bridge, arrangement, and parallel topologies.

**Linguistics**

Graph-theoretic strategies, in several shapes, have demonstrated especially valuable in phonetics, since dialect frequently loans itself well to discrete structure. Customarily, syntax and compositional semantics take after tree-based structures, whose expressive control lies inside the rule of compositionality, displayed in an awfully various levelled graph. More contemporary approaches like head-driven structure grammar model the syntax of tongue using typed feature structures, which are directed acyclic graphs. Within lexical semantics, especially as applied to computers, modelling acceptation is a smaller amount complicated when a given word is thought in terms of related words; semantic networks are therefore important in linguistics.

**Physics and chemistry**

In condensed matter material science, the three-dimensional structure of complicated re-enacted nuclear structures is examined quantitatively by gathering insights on graph-theoretic properties related with the topology of the particles. Too, "the Feynman charts and rules of calculation summarize quantum hypothesis amid a shape in near contact with the exploratory numbers one has to get a handle on. In chemistry a graph makes a typical show for a particle, where vertices speak to particles and edges bonds. This approach is incredibly employed in computer processing of molecular structures, ranging from chemical editors to database searching. In statistical physics, graphs can represent local connections between interacting parts of a system, additionally because the dynamics of a physical process on such systems

**Social sciences**

Graph theory is additionally widely employed in sociology as how, as an example, to measure actors' prestige or to explore rumour spreading, notably through the utilization of social network analysis software.

**Biology**

graph theory is accommodating in science and preservation endeavors where a vertex can speak to districts where certain species exist (or possess) so the perimeters speak to relocation ways or development between the regions. This information is extremely important when gazing breeding patterns or tracking the spread of disease, parasites or how changes to the movement can affect other species.

**Mathematics**

In mathematics, graphs are useful in geometry and certain parts of topology like knot theory. Algebraic graph theory has close links with math. Algebraic graph theory has been applied to many areas including dynamic systems and complexity.

Other topics

A graph structure is usually extended by assigning a weight to each fringe of the graph. Graphs with weights, or weighted graphs, are accustomed represent structures within which pair wise connections have some numerical values. as an example, if a graph represents a road network, the weights could represent the length of each road.
