Anita marked it as to-read Jan 23, Although the definition of NP talks about decision problems, many NP-complete problems are more naturally formulated as optimization problems; for example, “Given a graph G and an integer k, ausielli G have a clique of size k or larger?

Mitch rated it liked it Nov 20, InputDependent and Asymptotic Approximation. If you are only going to read one book on approximation algorithms, get Vazirani’s book and not this one.

Approximation Algorithms Vijay V. Jon Approximagion marked it as to-read Jun 06, As every undergraduate CS major learns and high wusiello can be taught to understandNP-complete problems most likely have no polynomial algorithms to solve them. Combinatorial Optimization Problems and Their Vazirani’s book is a monograph, while this book is a textbook. No trivia or quizzes yet. A2 Functions and relations. In particular, when a problem is computationally hard i.

Vazirani Limited preview – This book documents the state of the art in combinatorial optimization, presenting approximate solutions of virtually all relevant classes of NP-hard optimization problems. Just a moment while we sign you in to your Goodreads account. Telorian marked it as to-read Feb 03, Refresh and try again.

In such cases, we may decide to restrict ourselves to compute a solution that, though not being an optimal one, nevertheless is close to the optimum and may be determined in polynomial time.

Introduction To Algorithms Thomas H.

The book also describes several approximation techniques and examples of proving inapproximability and ends with a Garey and Johnson-like catalogue of NP-complete problems and approximtion knowledge of their approximability or inapproximability. One notable example is the type of approximation that arises in numer ical analysis or in computational geometry from the fact that we cannot perform computations with arbitrary precision and we have to truncate the representation of real numbers.

Want to Read saving…. The text smoothly integrates numerous illustrations, examples, and exercises.

Overall, this book is less interesting than Vijay Varirani’s Approximation Algorithms, which goes through several representative NP-complete problems and discusses in detail the approximation algorithm for each.
