Graph Theory
Graph Theory. Instructor: Dr. L. Sunil Chandran, Department of Computer Science and Automation, IISc Bangalore. In computer science, graph theory is used extensively. The aim of this course is to introduce the subject of graph theory to computer science students in a thorough way. While the course will cover all elementary concepts such as coloring, covering, hamiltonicity, planarity, connectivity and so on, it will also introduce the students to some advanced concepts.
