Description
This book is intended to be used as the text for a first course in combinatorics. the text has been shaped by two goals, namely, to make complex mathematics accessible to students with a wide range of abilities, interests, and motivations; and to create a pedagogical tool, useful to the broad spectrum of instructors who bring a variety of perspectives and expectations to such a course.
Features retained from the first edition:
 Lively and engaging writing style
 Timely and appropriate examples
 Numerous wellchosen exercises
 Flexible modular format
 Optional sections and appendices
Highlights of Second Edition enhancements:
 Smoothed and polished exposition, with a sharpened focus on key ideas
 Expanded discussion of linear codes
 New optional section on algorithms
 Greatly expanded hints and answers section
 Many new exercises and examples
