Graph Theory is, as far as we know, the first to be written by this approach. Its initial purpose was to serve as a high-school textbook for students learning graph theory in a systematic and orderly manner. Until the publication of this book, graph theory was only taught in academic institutions. The book soon began to serve as a reference book and even as a textbook in colleges and academic institutes for lecturers and students of mathematics and computer science. The book in its current format includes five chapters: 1. Definitions, Examples and Basic Concepts; 2. Paths and Circuits in Graphs; 3. Trees 4. Networks 5. Games, Puzzles and Graph Theory. The intention is to release it in a new and expanded edition.
