This book is intended for an upper-division or graduate course in algorithms. It has sufficient material to allow several choices of topics. The purpose of the book is threefold. It is intended to teach algorithms for solving real problems that arise frequently in computer applications, to teach basic principles and techniques of computational complexity (worst-case and average behavior, space usage, and lower bounds on the complexity of a problem), and to introduce the areas of !NT-coinpleteness and parallel algorithms.

Another of the book’s aims, which is at least as important as teaching the subject matter, is to develop in the reader the habit of always responding to a new algorithm with the questions: How good is it? Is there a better way? Therefore, instead of presenting a series of complete, “pulled-out-of-a-hat” algorithms with analysis, the text often discusses a problem first, considers one or more approaches to solving it (as a reader who sees the problem for the first time might), and then begins to develop an algorithm, analyzes it, and modifies or rejects it until a satisfactory result is produced. (Alternative approaches that are ultimately rejected are also considered in the exercises; it is useful for the reader to know why they were rejected.)
