Foundations of Graph Theory: Directed and Undirected Graphs

Graphs are the hidden backbone of modern technology, powering everything from social networks to routing algorithms and recommendation engines. To build efficient software and analyze complex data, you must first master how connections are structured and represented. This text-based course guides you from absolute beginner to a confident problem solver in graph theory. You will transition from understanding basic network structures to representing complex relationships in code and mathematical notation. By reading detailed breakdowns and analyzing step-by-step examples, you will build a strong theoretical foundation that translates directly to computer science and data analysis. What you'll learn: - Understand the foundational definitions of vertices, edges, and graph structures - Distinguish between directed and undirected graphs and their real-world applications - Represent graphs using adjacency matrices and adjacency lists with modern code patterns - Analyze graph properties such as degree, connectivity, paths, and cycles - Practice modeling real-world networks using structured, step-by-step written exercises The course begins with fundamental terminology and core mathematical concepts before moving into practical representation techniques. You will then explore traversal concepts and analyze how these structures function in modern software systems. This course is designed specifically for beginners, students, and self-taught developers who want a clear, math-first introduction to graphs without any complex prerequisites.
