For probabilistic decoding of LDPC and turbo codes in belief network Factor graph is used. Graphs are extremely power full and yet flexible tool to model. There are different operations that can be performed over different types of graph. — This paper aims to emphasize the applications of graph theory in daily life and technologies (Computer science, Operation Research, Chemistry). BioData Mining 2011 4:10. http://en.wikipedia.org/wiki/Flow_network. The first thing I do, whenever I work on a new dataset is to explore it through visualization. On the other hand graphs are used in many applications as a powerful tool to solve large and complicated problems. Hi, I wish to know which one is the reference paper [10]? Euler circuit: An Euler path in which a starting vertex of the path is same as ending vertex of the path is called as Euler circuit (closed path). The major areas that widely use graphs are Bio chemistry, Genomics, Electrical engineering – communication networks and coding theory, Computer Science – algorithms and computations, Operation Research – scheduling. Graph theory, like many fields of mathematics, can provide a more precise way of describing what people in the real world are already doing. General: Routes between the cities can be represented using graphs. Theory is the topography of our strategic map, determining our starting point and our destination, where we lay down paths, and how we focus and direct our energy. Graphs are widely used in following biological analysis; Protein-protein interaction (PPI) networks, Regulatory networks (GRNs), Signal transduction networks, and Metabolic and biochemical networks. All flight, train and subway networks form graphs, which can … Simple graph: A graph G= (V, E) with no loops and no multiple edges (parallel edges) is called simple graph. This paper contains definitions of different types of graphs by which helps to provide proper understanding on graph theory. Well in itself, Graph Theory is an important area of Discrete Mathematics. In Facebook Graph Search engine search algorithm is same, as Google search engine algorithm so searching will very faster in Facebook site.” Thank you in advance. Everything is becoming computer oriented. 8, pp. . Your email address will not be published. A subset M of G is called a spanning tree of graph G, if M is a tree and M contains all the vertices of graph G. Cut vertex: Let G= (V, E) be a connected graph. After that major application of these graph. Discrete Mathematics in the Real World. Later various applications of graph theory has been identified and divided as per their fields. Each type of graph is associated with a special property. flow. A vertex v G is called a cut vertex of graph G, if G – V results in a disconnected graph G. Cut edge: Let G= (V, E) be a connected graph, An edge e G is called a cut edge of graph G, if G-e result in a disconnected graph G. Euler graph: A connected graph G=(V, E) is said to be Euler graph (traversable), if there exists a path which includes, (which contains each edges of the graph G exactly once) and each vertex at least once (if we can draw the graph on a plane paper without repeating any edge or letting the pen). In the textbook the register allocation method is to model as graph coloring model. Residents of the Prussian city of Kongisberg, which was bisected by a river, had long pondered this puzzle. The new semantic search engine, which is known as Facebook Graph Search introduce by Facebook in March 2013. 8.) one of the compiler optimization technique for register allocation to improve the execution time is register allocation method, in which most frequently used values of the compiled program are kept in fast processor registers[5]. Because of the representation power of graphs and flexibility many problem can be represented as graphs and easily solved. Example: The graph given in figure 1 has vertex set V={1,2,3,4,5,6} and edge set={(1,2),(1,3),(2,3),(3,4),(3,5),(4,5),(5,6)}. This way it can be identified that which page is accessible form which page. A graph is a data structure that is defined by two components : A node or a vertex. An edge represents a relationship between nodes. detail of graph theory fail to give brief details about where those concepts are used in real life applications. Its applications extend to operations research, chemistry, statistical mechanics, theoretical physics, and socioeconomic problems. Tanner graph is an application of bipartite graph so, vertices are divided into two parts in which first bipartition represent the digit of code word, and the other side bipartition represent the combination of digits that are expected to sum zero in a code word without errors [3]. The importance of Algebra in real life is play vital role too. Materials covering the application of graph theory often fail to describe the basics of the graphs and their characteristics. In biology analysis the number of components of the system and their interactions is distinguish as network and they are normally represented as graphs where lots of nodes are connected with thousands of vertices [6]. Use of graphs is one such visualization technique. Your email address will not be published. In computer network graph is used to form a network of nodes and enable efficient packet routing in the network. A link between exists if there is a link between two pages. The obvious relevance has to do with our natural ability of abstraction.

We will describe the connection by the real-life logistics problems and graph theory. Among those one of the components is compiler. This includes finding the shortest paths between the nodes, analyze the current network traffic and find fasted root between the nodes, finding cost efficient route between the nodes. I'll give a couple examples: A collection of computers and communication links between the machines---a network. - computer science and engineering 1st year section ‘a’ project : coloring of graphs and its applications group members : •manojit chakraborty roll no. Graph: A graph usually denoted G(V,E) or G= (V,E) consists of set of vertices V together with a set of edges E. The number of vertices in a graph is usually denoted n while the number of edges is usually denoted m [1]. In this operation research directed graph is called network, the vertices are called as node, and the edges are called as arcs. The problems that can be solved by graphs cover many fields such as chemistry, biology, computer science, operational research. Likewise isomorphism there is sub graph can also be applied for the biological analysis method. In the interests of clarity, we shall now give a brief outline of the main topics covered throughout the rest of … There are many application of the network flow model, like some of them are picture a series of water pipes fitting into a network [7], Kirchhoffs current law, ecology, food web, information theory, thermodynamics,Robert Ulanowicz [7]. L. Euler, ªSolutio Problematis ad Geometriam Situs Pertinentis, Commentarii Academiae Scientiarum Imperialis Petropolitanae, vol. A graph shows information that equivalent to many words. In this paper authors have provided basic definitions that are crucial part of graph theory. 2. Graph theory is also widely used in sociology as a way, for example, to measure actors' prestige or to explore rumor spreading, notably through the use of social network analysis software. The field of mathematics plays vital role in various fields. It's often said that mathematics is useful in solving a very wide variety of practical problems. The machine that creates connection between this components a printed circuit board takes input in the form of a graph where edges denotes that there is a connection between the pair of components. Oxford, U.K.: Oxford Univ. M. Tech. The main objective of this article is to present the importance of graph theory in di erent branches of science and our everyday life . In this paper we demonstrate various graphs with their definitions, basic understanding and finally their importance and applications in real world. http://en.wikipedia.org/wiki/Bipartite_graph#Ad ditional_applications. Due to the gradual research done in graph theory, graph theory has become relatively large subject in mathematics. The head that creates this connection on the board then find the optimal to moves across the chip to get the desired resultant circuit. Vertex: The vertex is the point at which two rays (edges) of an angle or two edges of polygon meet. Linguistics: The parsing tree of a language and grammar of a language uses graphs. Biggs, E.K. Undirected graph: An undirected graph is one in which edges have no orientation. Since networks are everywhere, graph theory is everywhere, too. According above example, we must have knowledge about graph theory then only we can understand the concept of biological analysis in the real world. Proper understanding of various graphs present in graph theory is required to achieve understanding in real world applications. Hence this paper gives clear idea of use of terminologies of the graph theory in real world applications, covering both basic knowledge and brief of where these terminologies. graph theory includes Resource allocation, distance minimization, network formation, optimal path identification, data mining, circuit minimization, image capturing, image processing. The one of simplest and common approach, which is used network flow, is maximum network. Figure 6: Example of maximum flow network. {MathILy, MathILy-Er} focus on discrete mathematics, which, broadly conceived, underpins about half of pure mathematics and of operations research as well as all of computer science. In computer networks nodes are connected to each other via links. At the start of our journey, we don’t need to get bogged down in ultra-complicated minutiae—better to zoom … Press, 1976. “The new semantic search engine, which is known as Facebook Graph Search introduce by Facebook in March 2013. Edges are denoted by e= (v, u) it is pair of two vertices. Acquaintanceship and friendship graphs describe whether people know each other. Contextualization - context or situation of individual’s life 6. If among two graph one of the graphs is sub graph than in biological analysis the sub graph component formula can be derived from main biological graph component. makes use of one of this graph in order to fine solution to the problems. IN a letter to C. Huygens of 1679, G.W. There for to properly implement this applications and to manage them it is necessary to have clear idea of graph theory. or A simple graph G= (V, E) in which every vertex in mutually adjacent to all other vertices is called a complete graph G. Cycle graph: A simple graph G= (V, E) with n vertices (n3), n edges is called a cycle graph. Figure 6 is example of maximum flow, in which 11 is maximum flow in network. 1451048 •pallavi mazumder roll no. Such a path is called Euler path. 1451050 •saptarshi kundu roll no. Pranav Patel, Chirag Patel, 2013, Various Graphs and Their Applications in Real World, INTERNATIONAL JOURNAL OF ENGINEERING RESEARCH & TECHNOLOGY (IJERT) Volume 02, Issue 12 (December 2013), Various Graphs and Their Applications in Real World. Due to its graphical (visual) property, it becomes easier for users to discover patterns and relationships. Graphs also play an important role in transportation and navigation. Wheel graph: A wheel graph G= (V, E) with n vertices (n4), is a simple graph which can be obtained from the cycle graph Cn-1 by adding a. new vertex (as a hub), which is adjacent to all vertices of Cn-1. Who would’ve thought that connect-the-dots would be so important to our world? If we analysis above components than it will be generated the structure network which is similar to one of the graph component in graph theory. Materials covering application of graph theory often fail to describe the basics of the graphs and their characteristics. In language processing in the tools like compiler parse tree are used to identify if the input is having correct syntactic structure or not. We often speak of collection of things as a single entity, “the Detroit A. Sanfilippo, in Encyclopedia of Language & Linguistics (Second Edition), 2006. This structures are created based on the properties of compounds and are taken for analysis and processing. In electronic chip design each component is considered as a vertex of the graph. Graph theory can solve majority of computational problems in industry. Due to the gradual research done in graph theory, graph theory … For example Factor graph and Tanner graph is manly used for decoding the code. Use of graph theory is extreme when it comes to the computer science application. This paper explains where different graphs of graph theory are used in these real world applications. which are, receives from the channel. Graphs are used to model molecule structures for computer processing. This can be used to study the structure of molecules and to check similarity level between molecules. Maths, the least popular subject of the school. Most application. There are many types of graphs as a part of graph theory. This paper gives an overview of applications of graph theory in heterogeneous fields but focuses on Computer Science applications that uses graph theoretical concepts. Graph theory is a branch of discrete combinatorial mathematics that studies the properties of graphs. Diversified data in real-life situations - collecting data in a natural setting 7.

For example: traffic organization, social relations, artificial intelligence and so on. A Graph Theory is a very vast subject; it is also extensively used for the analysis in biological networks. However, before that, let us shed some light on what exactly Algebra is all about. Raw click frequency is to weight the query and URL on click graph. Graph isomorphism method can be used for matching two components in, In operation research the network flow (also called as transportation network) is directed graph application where each edge has a capacity and each edge receives a flow, where the amount flow cannot be exceed the capacity of the edge [7]. An overview is presented especially to project the idea of Graph Labeling. Graph theory is used everywhere Hence graphs theory is useful in many applications and these applications are widely used in real world. Graph theory is used to model and study all kinds of things that affect our daily lives: from transatlantic shipping routes to integrated circuits, from molecular bonds to animal food webs. And this approach has worked well for me. In Facebook Graph Search engine graph Search feature combines external data into a search engine providing user-specific search results and the big data acquired from its over one billion users [10]. Complete graph: A simple graph G= (V, E) with n mutually adjacent vertices is caled a complete graph G and it is denoted by Kn. Computer networks are extremely popular in todays life. Standard algorithms such as Dijkstras algorithm, Bellman-Ford algorithm are used to in the various ways with graph to find the solutions. While this advancement is at its peak the most of the largely used applications one way or the other use graph theory, like search engines are largely based on graphs. There for graph theory can be considered large and complicated subject. theory are given in various subjects. Relational Database They play an important part in almost every organization that keep track of its employees, clients or resources. important applications of Graph Theory in Biology: the phenomenon of synchronisation and its role in neurological disorders, and the interaction between network structure and epidemic dynamics. Bipartite graph: A simple graph G= (V, E) with vertex partition V= {V1, V2} where V1, V2. Complete bipartite graph: A bipartite graph G= (V, E) with vertex partition V1, V2 is called a complete bipartite graph if every vertex in V1 is adjacent to every vertex in V2. — This paper aims to emphasize the applications of graph theory in daily life and technologies (Computer science, Operation Research, Chemistry). These properties separates a graph from there type of graphs. A subset K of V is called a vertex covering of graph G, if every edge of graph G is incident with a vertex in K. Spanning tree: Let G= (V, E) be a graph. N.L.
