Graph Theory is a fundamental mathematical concept that studies the relationships between objects, representing them as graphs comprising vertices and edges. Coursera's Graph Theory catalogue teaches you the principles and applications of this important mathematical construct. You'll learn how to model real-world problems using graphs, understand graph traversal algorithms like breadth-first and depth-first search, and explore advanced topics such as shortest path algorithms, spanning trees, network flows, and graph colorings. This knowledge will help you tackle complex problems in fields such as computer science, operations research, and data analysis.
