In computer science and operations research, approximation algorithms are efficient algorithms that find approximate solutions to optimization problems (in particular NP-hard problems) with …

This book is suitable for use in advanced undergraduate and graduate level courses on approximation algorithms. It has more than twice the material that can be covered in a …

Today’s lecture focuses on the first idea, to derive polynomial-time approximation algorithms.

Approximation algorithms: procedures which are proven to give solutions within a factor of optimum. Of these approaches, approximation algorithms are arguably the most …

Approximation algorithms are algorithms designed to solve problems that are not solvable in polynomial time for approximate solutions. These problems are known as NP complete problems.

In each of the 27 chapters an important combinatorial optimization problem is presented and one or more approximation algorithms for it are clearly and concisely described and analyzed.

The approximation ratio for your overall algorithm is the largest a / o a/o for any possible input. If you problem is a minimization problem, the approximation ratio is defined as o / a o/a, so that …

May 19, 2025 · Explore how to design and analyze approximation algorithms in discrete mathematics, offering efficient solutions to NP-hard problems.

A Fully Polynomial Time Approximation Scheme (FPTAS) is an approximation algorithm that runs in time polynomial in both n and c. For example, a O(n2/E) approximation algorithm is a PTAS …
