A11 Sequences tuples and matrices. A8 Two famous formulas. In other cases, we use to approximate com plex mathematical objects by simpler ones: 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.

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.

The need to solve difficult optimization problems is another reason that forces us to deal with approximation.

Approximatiln by Giorgio Ausiello. Thanks for telling us about the problem. This book documents the state of the art in combinatorial optimization, presenting approximate solutions of virtually all relevant classes of NP-hard optimization problems. Design Techniques for Approximation Algorithms.

Although the definition of NP talks about decision problems, many NP-complete problems are more naturally formulated as optimization problems; for example, “Given a approximatiln G and an integer k, does G have a clique of size k or larger? Approximation Algorithms Vijay V.
