Basic concept of Graph theory is going to be discussed in this video lecture. <br />Graph theory is the study of representation of graphs and it is used in In mathematics and computer science. A "graph" is made up of "vertices" or "nodes" and lines called edges that connect them. A graph may be un-directed, meaning that there is no distinction between the two vertices associated with each edge, or directed graph where its edges may be directed from one vertex to another <br />In computer science, graphs are used to represent networks of communication, data organization, computational devices, the flow of computation, etc. <br /> <br />Contact: Debarghya Mukherjee <br />Mobile: (+91)-9038787021 <br />Email: Debarghya_mkr@yahoo.com
