Introductory Discrete Mathematics by V. K. Balakrishnan
This overview of discrete mathematics places special emphasis on combinatorics, graph theory and two important topics in network optimization with an algorithmic approach. The text provides a discussion of basic combinatorics and graph theory, with several combinational models. The text includes: a brief exposition of the theory of NP completeness; more than 100 diagrams and tables directly tied to subject matter; historical notes and references in each chapter; end-of-chapter exercises; and a bibliography.
