The definitive reference for data structures and algorithms

While working as a software engineer, my supervisor, who also wrote programs for a living, had a book on his shelf, "Data Structures and Algorithms", written by Horowitz and Sahni. It was one of the most tattered-looking hardback books I had ever seen! (a true indicator of the worth of a book). Moreover, I view the Cormer, Leiserson, Rivest book as an updated version of this book, in that it has the same core content of data structures and algorithms, and presents the algorithms in psuedocode instead of a GPL like C++. I find this book, however, not only better written than its predecessor, but also containing a number of advanced chapters (e.g. computational geometry and parallel computation) that reflects the explosion of the study of algorithms over the past 20 years. If I had to choose one book on data structures and algorithms to have on my shelf it would be this one, as no other modern text compares with it in terms of its breadth and depth of the subject material. However, for those students or practitioners who prefer to learn about data structures and algorithms within the context of a progromming language, I recommend Mark Weiss's book on data structures and algorithms, both in Java and in C++. His book seems less developed and rigorous, but he gives good examples, explanations, and more practical insights.

The New Edition is Great!

For years, I've looked for a single algorithms book that would cover all of the bases and provide an up-to-date replacement for the 3 Knuth volumes. The 2001 edition of CLR is it. I had looked at earlier versions of CLR and somehow not seen what I wanted; seemed too much like a enumeration of algorithms rather an explanation of them. But what the other reviewers say about CLR is definitely true of this edition. Its the one you want on your shelf to accompany your career in software or computer science.The reviewers who knocked off stars for being difficult were probably also correct; this book is not for community college course with students who earned Cs in math and programming courses. In fact, I question the word "introduction" in the title. Yes, it only assumes minimal math and programming knowledge, but it goes a long ways into the topic. Sure, it might not cover some exotic academic topics or some very specialized topics, but if you are a software engineer it has all you are likely to want or need in your practical work (until there are new research results that prove important in industry) unless you work in area that requires specialized algorithms.One topic regretablly omitted from this book, and most other books on algorithms, is extendible hashing, hashing techniques that support an arbitrary, unkown amount of data. Papers by Fagin and Litwin describe such methods.

What every computer scientist should have

If one were to make a list of the 100 best books in computer science, then winnow that list down to 10 books, and then again down to 1 book, surely this would be that book.Known in computer science circles as CLR (for the authors) or simply, "The White Book", Introduction to Algorithms by Cormen, Leiserson, and Rivest is the de-facto standard text for algorithms and data structures. It covers all the basic subjects (big-O notation, trees, graphs, etc...) as well as a few intermediate subjects (amortized analysis, matroids, etc...). Of course, this book is not the be-all and end-all of computer science nor does it pretend to be. It touches on NP-completeness only lightly and all but omits randomization; but if you wanted a text on NP-completeness, you would be reading Garey & Johnson and if you wanted randomization you'd go to Motwani & Raghavan. But if you need a reference on data structures and algorithms, this is the book for you.Now, some have complained that while this book is an excellent reference that it is a poor text to learn from. I beg to differ. I concede that it is certainly more demanding than many other introductory texts, but this is a boon not a curse. By remaining true to computer science's mathematical heritage, Cormen et al. force the reader to become accustomed to rigourous, formal reasoning, something which is unfortunately absent in many computer science curricula. The authors present the concepts cleanly and clearly, without the distraction of any specific programming language/paradigm. Perhaps it is this removal from a familiar C/C++/Java/flavour-of-the-month/etc... milieu which makes some readers nervous. But it is precisely this separation which forces the reader up into the realm of abstraction where computer science truly resides.

Rigorous coverage of the most widely used algorithms

I personally bought this book in preparation for the International Olympiad in Informatics (IOI), and it helped me immensely in getting off the ground with the algorithms I had to learn, especially the chapter on Dynamic Programming. Since then, however it has remained a priceless companion during my studies and at home.This is the definitive reference for algorithms with a firm theoretical and mathematical foundation. Algorithms are treated with a thorough theoretical introduction often with a complete mathematical walkthrough, a clearly thought out solution, a discussion of its pros and cons, lots of clear and consisive diagrams, a pseudocode implementation, and a good deal of serious optimisation discussion. It's written in an accessible manner, starting with the elementary issues, progressing to the advanced and complex thinking needed to conquer them, so you'll find you have to give it your full concentration.This book will not disappoint. Its explanations are rigorous and its coverage spans all the general purpose algorithms with little focus on their applications but rather on the algorithms themselves. The book covers such major areas as sorting, data structures, advanced design and analysis techniques, graphs, each about a hundred pages on average, and a selection of specialised algorithms such as parallel programming, string matching and computational geometry. Because these algorithms are used everywhere, from games, graphics and simulations to electrical engineering it will have a broad audience and will find a home almost anywhere there is serious programming involved. Each chapter is a unit in itself which means you don't need to read it cover to cover, since they all start off smoothly and handhold you through. Clearly written by professionals, this is the book I know contains the information that I can't find elsewhere.
