The need to solve wusiello optimization problems is another reason that forces us to deal with approximation. Gosh I really don’t feel like reading this book, but my advisor is teaching the class and he asked me to take it because he didn’t have enough students enrolled.

Gilles Simonin added it Oct 14, 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 ausiel,o and we have to truncate the representation of real numbers.

Complexity and Approximation

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. Vazirani’s book is a monograph, while this book is a textbook.

The current state of knowledge of approximation algorithms. A2 Functions and relations. 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. Paulo Siqueira marked it as to-read Aug 20, Vazirani Limited preview – We call this type of solution an approximate solution and the corresponding algorithm a polynomial-time approximation algorithm.
