Some books on algorithms are rigorous but incomplete; others cover masses of material but lack rigor.�Introduction to Algorithms�uniquely combines rigor and comprehensiveness. It covers a broad range of algorithms in depth, yet makes their design and analysis accessible to all levels of readers, with self-contained chapters and algorithms in pseudocode. Since the publication of the first edition,�Introduction to Algorithms�has become the leading algorithms text in universities worldwide as well as the standard reference for professionals. This fourth edition has been updated throughout.
