Douglas B. West’s Introduction to Graph Theory remains a cornerstone of discrete mathematics. Its blend of readability and depth makes it the perfect resource for anyone serious about understanding the networks that define our modern world—from social media algorithms to transportation logistics.
This chapter moves from definitions to connectivity. West introduces walks, trails, paths, cycles, and components. He then dives into bipartite graphs (characterized by the absence of odd cycles) and graph isomorphism algorithms. He includes a dense section on "Graphic Sequences" (the Havel-Hakimi algorithm), which many other texts ignore. introduction to graph theory by douglas b west pdf

Graph theory involves reviewing definitions constantly. A digital PDF allows students to search for key terms like "bipartite," "Eulerian," or "Hamiltonian" instantly—something impossible with a physical index. This chapter moves from definitions to connectivity
Matchings involve selecting edges that do not share vertices. The text covers Hall’s Marriage Theorem and Tutte’s Theorem, which are foundational for resource allocation, job scheduling, and network optimization problems. 4. Connectivity and Paths
Solid, systematic coverage of classical graph theory; authoritative presentation of standard theorems; excellent collection of exercises; valuable as a course textbook or long-term reference.
