The development of algorithms to handle graphs is therefore of major interest in computer science.

Graph theory - Wikipedia

The transformation of graphs is often formalized and represented by graph rewrite systems. Complementary to graph transformation systems focusing on rule-based in-memory manipulation of graphs are graph databases geared graph theory with applications transaction -safe, persistent storing and querying of graph-structured data.

Linguistics[ edit ] Graph-theoretic methods, in various forms, have proven particularly useful in linguisticsgraph theory with applications natural language often lends itself well to discrete structure. Traditionally, syntax and compositional semantics follow tree-based structures, whose expressive power lies in the principle of compositionalitymodeled in a hierarchical graph.

More contemporary approaches such as head-driven phrase structure grammar model the syntax of natural language using typed feature structuresgraph theory with applications are directed acyclic graphs.

Within lexical semanticsespecially as applied to computers, modeling word meaning is easier when a given word is understood in terms of related words; semantic networks are therefore important in computational linguistics. Still, other methods in phonology e.

Indeed, the usefulness of this area of mathematics to linguistics has borne organizations such as TextGraphsas well as various 'Net' projects, such as Graph theory with applicationsVerbNetand others.

Physics and chemistry[ edit ] Graph theory is also used to study molecules in chemistry and physics.

In condensed matter physicsthe three-dimensional structure of complicated simulated atomic structures can be studied quantitatively by gathering statistics on graph-theoretic properties related to the topology of the atoms. Also, "the Feynman graphs and graph theory with applications of calculation summarize quantum field theory in a form in close contact with the experimental numbers one wants to understand.

This approach is especially used in computer processing of molecular structures, ranging from chemical editors to database searching.


In statistical physicsgraphs can represent local connections between interacting parts of a system, as well as the dynamics of a physical process on such systems. Similarly, in computational neuroscience graphs can be graph theory with applications to represent functional connections between brain areas that interact to give rise to various cognitive processes, where the vertices represent different areas of the brain and the edges represent the connections between those areas.

Graph Theory with Applications

Graph theory plays an important role in electrical modeling of electrical networks, here, weights are associated with resistance of the wire segments to obtain electrical properties of network structures.

Graph theory in sociology: Moreno Sociogram [10] Graph theory is also widely used in sociology as a graph theory with applications, for example, to measure actors' prestige or to explore rumor spreadingnotably through the use of social network analysis software.

Under the umbrella of social networks are many different types graph theory with applications graphs.


Influence graphs model whether certain people can influence the behavior of others. Finally, collaboration graphs model whether two people work together in a particular way, such as acting in a movie together. Biology[ edit ] Likewise, graph theory is useful in biology and conservation efforts where a vertex can represent regions where graph theory with applications species exist or inhabit and the edges represent migration paths or movement between the regions.

This information is important when looking graph theory with applications breeding patterns or tracking the spread of disease, parasites or how changes to the movement can affect other species. Mathematics[ edit ] In mathematics, graphs are useful in geometry and certain parts of topology such as knot theory.

Algebraic graph theory has close links with group theory.

Other topics[ edit ] A graph structure can be extended by assigning a weight to each edge of the graph. Graphs with weights, or weighted graphsare used to represent structures in which pairwise connections graph theory with applications some numerical values.

For example, if a graph represents a road network, the weights could represent the length of each road.

There may be several weights associated with each edge, including distance as in the previous exampletravel time, or monetary cost.

Such weighted graphs are commonly used to program GPS's, and graph theory with applications search engines that compare flight times and costs.

Graph theory

Euler's formula relating graph theory with applications number of edges, vertices, and faces of a convex polyhedron was studied and generalized by Cauchy [13] and L'Huilier[14] and represents the beginning of the branch of mathematics known as topology.

The techniques he used mainly concern the enumeration of graphs with particular properties.


These were generalized by De Bruijn in Cayley linked his results on trees with contemporary studies of chemical composition. In particular, the term "graph" was introduced by Sylvester in a paper published in in Naturewhere he draws an analogy between "quantic graph theory with applications and "co-variants" of algebra and molecular diagrams:
