Design Techniques for Approximation Algorithms.

Complexity and Approximation

Overall, this cokplexity 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. Selected pages Title Page. Cenny Wenner rated it really liked it Apr 26, Gilles Simonin added it Oct 14, Dec 26, Ushan rated it liked it Shelves: Vazirani’s book is a monograph, while this book is a textbook.

In formal terms, they are classified as Np-hard optimization problems. One notable example is the conplexity of approximation that arises in numer ical analysis or in computational geometry from the fact that we cannot perform computations Trivia About Complexity and Ap To see what your friends thought of this book, please sign up.

Complexity and Approximation

As every undergraduate CS major learns and high schoolers can be taught to understandNP-complete problems most likely have no polynomial algorithms to solve them. Published February 1st by Springer first published November 9th The wealth of problems, algorithms, results, and techniques make it an indispensible source of reference for professionals.

Foo Bar marked it as to-read Feb 17, Mitch rated it liked it Nov 20, 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 the knowledge of their approximability or inapproximability.


If you are only going to read one book on approximation algorithms, get Vazirani’s book and not this one. Hardcoverpages.
