Introduction to Algorithms, 4th Edition by Cormen, Leiserson, Rivest & Stein (Hardcover)

Introduction to Algorithms, Fourth Edition, is the MIT Press hardcover textbook by Cormen, Leiserson, Rivest, and Stein (CLRS) used in university algorithms courses and kept as a desk reference by working software engineers.

Most people know this book simply as CLRS. It has been the leading algorithms text in universities worldwide since the first edition, and it remains the reference professionals reach for when they need a correct, rigorous treatment of an algorithm. Chapters are self-contained, algorithms are written in pseudocode, and the analysis is accessible without being watered down. The fourth edition was updated throughout.

What's included

• Introduction to Algorithms, Fourth Edition (MIT Press, 2022)

• New material on solving recurrence equations, hash tables, potential functions, and suffix arrays
• 140 new exercises and 22 new problems, plus updated notes, bibliography, and index
• Access to the publisher’s website with supplementary material

Who it's for

Undergraduate and graduate computer science students taking a first or second algorithms course, software engineers preparing for technical interviews, and researchers who want one authoritative reference for sorting, graph algorithms, dynamic programming, and NP-completeness. It also suits self-taught programmers who are ready for a mathematical treatment rather than a tutorial.

Why this edition

The fourth edition is the first major revision of CLRS in over a decade. Beyond the new chapters, the writing was revised to be clearer and more direct, color was added throughout, and the problem sets were reworked using reader feedback. If a course syllabus lists CLRS without naming an edition, this is the current one; chapter numbering differs from the third edition in places, so match the edition your instructor assigns.
