Graph Theory 2031 Words | 9 Pages. A graph G is a mathematical structure consisting of two sets V(G) (vertices of G) and E(G) (edges of G). Due to its capacity of handling large data, graph theory is of some special interest as it can be applied to many problems including problems in management sciences (Harary 1959), social sciences (Harary and Norman 1953), computer sciences. Graph-theoretic applications and models usually involve connections to the ”real types of real life problems. (Conclusion) Every binary structural relation can be described by a graph. the edge between a and b will be labeled as s. Three sections are defined here. The viability of PFG is shown by utilizing the concept in demonstrating two real-life problems including a social network and a Wi-Fi-network.
