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 Open Preview See a Problem? 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.
Refresh and try again. Tuy added it Apr 11, This book documents the state of the art in combinatorial optimization, presenting approximate solutions of virtually all relevant classes of NP-hard optimization problems. 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.

Just a moment while we sign you in to your Goodreads account. Combinatorial Optimization Problems and Their We call this type of solution an approximate solution and the corresponding algorithm a polynomial-time approximation algorithm.
Vazirani Limited preview – Brian33 added it Jun 08, 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.
Design Techniques for Approximation Algorithms. Most combinatorial optimization problems of great practical relevance are, indeed, computationally intractable in the above sense. 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, does G have a clique of size k or larger?
Complexity and Approximation
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.
