How does Google Maps know how to route you from one location to another? How does Instagram recommend you videos that other people you follow liked? How does your phone provider know how to route your call to the person you're calling optimally? The answers to all of these questions have one thing in common: they're applications of graph theory. Graph theory, the study of related objects, is one of the fundamental building blocks of discrete mathematics. In this course, students will learn the answers to these questions (and more!) by being exposed to the basics of what a graph is from a computer science perspective by exploring some common representations and graph traversal algorithms.
