Graph theory is an important branch of applied mathematics with a lot of applications in many fields. Graph theory has a broad scale of applications in many practical situations. Graph coloring is one decent approach which can deal with many problems of graph theory. The main aim of this paper is to present the importance of graph coloring ideas in various fields for researchers that the concept of graph theory can be used by them. In this paper an overview is presented especially to project the idea of graph theory and applications of graph colouring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
