Amazon Summary
This text, extensively class-tested over a decade at UC Berkeley and UC San Diego, explains the fundamentals of algorithms in a story line that makes the material enjoyable and easy to digest. Emphasis is placed on understanding the crisp mathematical idea behind each algorithm, in a manner that is intuitive and rigorous without being unduly formal. Features include: The use of boxes to strengthen the narrative: pieces that provide historical context, descriptions of how the algorithms are used in practice, and excursions for the mathematically sophisticated. Carefully chosen advanced topics that can be skipped in a standard one-semester course, but can be covered in an advanced algorithms course or in a more leisurely two-semester sequence. An accessible treatment of linear programming introduces students to one of the greatest achievements in algorithms. An optional chapter on the quantum algorithm for factoring provides a unique peephole into this exciting topic. In addition to the text, DasGupta also offers a Solutions Manual, which is available on the Online Learning Center." Algorithms is an outstanding undergraduate text, equally informed by the historical roots and contemporary applications of its subject. Like a captivating novel, it is a joy to read."

I worked through this one on Dan Luu's recommendation and loved it: https://www.amazon.com/gp/product/0073523402

That's one wonderfully written book.
Algorithms [1] by Robert Sedgewick is particularly well written.

Also, this one [2] is quite good and concise. I believe better suited for someone who is not unfamiliar with classic algorithms (like you).

As an older self-taught engineer who went through interviews last year this is great advice. Other books I found particularly useful were:

Algorithms by Dasgupta, Papadimitriou and Vazirani:

And Elements of Programming Interviews by Aziz, Lee and Prakash:

Are you kidding me? The Vazirani/Dasgupta book is a joke compared to CLRS.

I learned algorithms from CLRS (as most students have), and it is bar-none, the best data structures/algorithms book on the market. The explanations are clear, detailed and rigorous.

The Vazirani/Dasgupta book does not go into as much detail. You don't believe me that this book is bad? Read some of the Amazon reviews: http://www.amazon.com/Algorithms-Sanjoy-Dasgupta/product-rev...

I don't see where we are disagreeing here - Vazirani/Dasgupta is not as detailed/rigorous as CLRS and that is precisely the point. The detail of CLRS comes at the cost of readability.

I'm not denying that I enjoyed learning from CLRS - but I recollect having to take more effort to parse its detailed pseudo-code than what a higher level of abstraction would've taken.

This is where a book with less detail like Vazirani can help. I would never recommend relying on a single text for studying anything - least of all Algorithms. Each of these complement the others in a nice way and being able to look at the same concept from the perspective of different authors always help.

You've pointed to the 3 one-star reviews instead of the 17 five-star reviews of the book. Was that a mistake? Joking aside, those reviews seem to be from people who've tried to use Vazirani as their sole Algorithms text. Having seen CLRS first, I've always approached Vazirani as a complement to CLRS and that worked.

Just bought this on Amazon, looks great but I still prefer dead trees for tech books. Awesome that they've released it for free online though, very cool!

Whoops, seems I posted the mobile link, here's the desktop site link: http://www.amazon.com/Algorithms-Sanjoy-Dasgupta/dp/00735234...

And here's the uk one: http://www.amazon.co.uk/Algorithms-Sanjoy-Dasgupta/dp/007352...

I had the pleasure of taking the class based around this book from Christos Papadimitriou while at UC Berkeley. It is indeed a concise and excellent book. If you see it in person you'll be surprised how short it is compared to most textbooks. I must confess, though, that some of the exercises can be absolutely maddening.
