Product Description This best-selling book provides an accessible introduction to discrete mathematics through an algorithmic approach that focuses on problem- solving techniques. This edition has the techniques of proofs woven into the text as a running theme and each chapter has the problem-solving corner. The text provides complete coverage of: Logic and Proofs; Algorithms; Counting Methods and the Pigeonhole Principle; Recurrence Relations; Graph Theory; Trees; Network Models; Boolean Algebra and Combinatorial Circuits; Automata, Grammars, and Languages; Computational Geometry. For individuals interested in mastering introductory discrete mathematics. | ||
Reviews | ||
I despise this book I've had this book for two semesters of a discrete mathematics course. The author is particularly fond of the word 'obviously'. The book includes a lot of proofs, but very poor explanation of how the author arrived at them. Every person I've ever met who used this book has absolutely hated it. | ||
I suppose it depends on who is reviewing it. I got something from the book even if it was mostly review for me. I liked the recursion and graph sections. I have Schaum's outlines: 1) Essential Computer Mathematics 2) Data Structures That cover some but not all of the same material. So why are the customer reviews so bad? The notation is hard for those unfamiliar with it? People with a good high school education should be able to get this is if it was taught well. So I think the problem is that college prep math is failing and college instructors are just as bad as they were in my time. Don't blame it on the text if the problem is your preparation for the subject and your instructor? This material is "need to know" for Mathematics and Computer Science majors. I thought it was pretty well done, but I'm not answering the questions in a class room setting. Maybe he tried to cover too much in one text? It actually (laughing well) really needs a group theory section. | ||
Garbage This book epitomizes the common flaw in higher education today-expecting that an "expert in a field" makes them an "expert teacher". Bull. This book is written by someone who has decided to write a book 6 levels above the education of their readers just so they can prove a point at how smart they are. I'll bet Johnsonbaugh is the kind of guy that just stands at the board writing his notes that he could just give to you, just so he can hear the glory of his own voice. I have taken 4 semesters of calculus as an undergrad, as well as various science graduate courses and am LOST when reading this book. This book may be good for math "majors," but for people looking in other fields (Computer science, for example) it is terrible. School administrators, take note: Find another book for your students. Just because this guy is an expert, doesn't mean he can come close to making everyone else one. Spend time studying the impact of this book, and you will see that this book is as effective in educating as a ruler to the knuckles. Johnsonbaugh should stay where he belongs-in the lab, solving the world's math problems and leave teaching up to the teachers. | ||
No Good This book is horrible. He doesnt define the words that a bolded either. Most of the time he uses the proofs themselves to define a word. That doesnt help anything especially when the proofs are confusing too. It seems like when he explains something, he is really saying the same thing over and over again. It is impossible to understand this book. | ||
The worst text book ever My university requires this book for the discrete mathematics course. I have to tell you, this book teaches you absolutely nothing! The author barely explains things. And when he does explain things, he explains them as if the person reading already has an indepth knowledge of advanced math. There is no explaination as to how he arrived at answers at the back of the book. I actually have to buy another book because I got so frustrated trying to learn this, that I ripped the book almost into shreds. And its only been two weeks into the term! I'm contemplating emailing the author to tell him to quit writing textbooks because this one is horrible. My recommendation is not to buy this book unless you have no other choice. | ||
