Discrete and combinatorial mathematics Book

*Appropriate for four different courses: Discrete Mathematics; Combinatorics; Graph Theory; Modern Applied Algebra. *Flexible, modular organization. *This text has an enhanced mathematical approach, with carefully thought out examples, including many examples with computer sciences applications. *Carefully thought-out examples, including examples with computer science applications. Students can learn by reading the text. *The Fourth Edition has added more elementary problems, creating a larger variety of level within the problem sets which allows students to establish skills as they practice. *Chapter summaries allow the student to review what they have learned, while historical reviews and biographies bring a human element to their assignments. 1.
