Summary: ..GREAT
Review: ..Amazing..now I see the beauty in mathematics..Knuth weaves magic..book is pure gem ..should be on every computer scientists table. Thank you very much for the book dear authors.

Summary: So far, a good read, I can't wait to read more.
Review: And, I hope I can get the time to finish it. This is a good prelude to some of the more agressive algorithm books out there, if you take any very advanced programming courses--and gets you mroe ready for some of the Knuth books (now there's a challenge).

Summary: Only one problem with this textbook
Review: Basically, I like this textbook. The material is interesting, the way the authors presented the material is inspiring, and they provided a lot of jokes to make even studying for exams not that boring. But there is one big problem which made me decided to rate this book only 3 stars instead of 5 stars: the authors like to use non-standard notations. For example: m\n means "m>0 and n=mk for some integer k". One of the worst thing in scientific world is writing things others cannot read, and the authors did this by introducing many strange notations. These things makes the good work sometimes almost unreadable. This is not computer systems in which we use "cp" for the copy command and "cd" for change directory command.What a pity the authors did that. This textbook will be perfect without those strange notations....

Summary: A book for pure mathematics , not calculus for engineers !
Review: hmm, well I myself am an engineer but also have an avid interest in maths..of course the maths average engineer uses is calculus , linear algebra et al. not pure maths..so a common engineer might be dissatisfied with this book. Neverhteless that shouldn't dissuade the maths enthusiast because this is one of the good books written on discrete maths essential for comp sci student and/or a maths major to get a sound grasp of the basics. I hope everyone benefits from this effort to popularise ancient pure maths in the world of abstract maths !

Summary: Bad fonts
Review: I can't find another book that covers similiar material at this depth. A great book possibly a future classic but unfortunately the font ("Euler" font which was created specifically for this book) is just awful which makes this book far more difficult to physically read than neccesary. Characters just sits like a rock instead of helping the eyes flow from one word to the next. I would give it 5 stars if not for the distracting swiggly font.

Summary: I keep this one always within reach
Review: I found this book very stimulating, and whenever I have a chance I go back to some of the harder problems. This book should please the more mathematically oriented programmers as well as anyone with curiosity regarding numerical mathematics. The scholarship is thorough and I find particularly noteworthy the attempt to ascribe soucres correctly and I appreciated the attention to detail (even the font used).

Summary: Fear first, love later
Review: I used this book while studying Combinatorics at the University of Warwick, a leading British institution for mathematicians. At the time, the book was a little bit overwhelming - Knuth doesn't waste any time in getting to the point of solving problems in the book. Thus, if you're the type of person who needs lots of worked examples, I would supplement this with another book, for example, Grimaldi's Discrete and Combinatorial Mathematics. But this book does belong on the bookshelf - it is a great reference, particularly because it prepares one to read The Art of Computer Programming, also by Knuth. TAOCP is the definitive series on computer science, respected by computer scientists everywhere. I guess the best way to describe Concrete Mathematics is that if you are a graduate student in CS, you should own this book. If you are a mathematically-oriented undergraduate, this book will make you really understand anything that your professors will throw at you. But, if you are not a math-lover, you will want a backup and a really nice professor :)

Summary: A pourry of combinatorics
Review: I want to start saying that this is a book designed for Engineers, not for Mathematicians. It focuses on the tecniques, not on the arguments. This is not a book about combinatorics, it is a wide raging introduction (it lacks on definitions, and his proofs are a lot far away from mathematical ones). The Enegineers can use this book as a good reference. The Mathematicians can improve their lateral thinking, for them (well: us) it is book about problem-solving strategies.
I will never use this book as a textbook for a graduate/undergraduate course, it can be helpful if used with another book about combinatorics: when you study a combinatorial object, you can read from this book the techniques it involves.
The exercises are extremely exciting, when I read this book I spent a lot of time about its exercises (proportion read:solve = 1:3), and they led me to interesting results.

Summary: Enjoyable next step
Review: I've greatly enjoyed this book. And while I haven't finished it _yet_, I can still tell you that this book is _very_ good for self study. I find myself applying what I've learned to "real" life (okay, the American Mathematics Competition -> 12). Not a bad decision if you plan to go further in math.

Summary: A great book for all undergraduated math students !!!
Review: In this book Knut explain very clearly various topics on math apllied to computation. In his very humorous style he teaches all the topics with fun. It has many beautiful results on integers, sumation e Fibonnaci numbers. Read it and enjoy it.
