Approximation Algorithms for Combinatorial Optimization: International Workshop Approx'98 Aalborg, Denmark, July 18-19,

Introduction

In the ever-evolving world of computer science and programming, the ability to solve complex problems efficiently is paramount. 'Approximation Algorithms for Combinatorial Optimization' stands as a seminal collection of research papers from the prestigious International Workshop Approx'98, held in Aalborg, Denmark. Edited by the renowned Klaus Jansen and published by Springer, this hardcover volume captures the cutting-edge discussions and findings on how to tackle NP-hard problems when exact solutions are computationally infeasible. For Indian students, researchers, and professionals diving into advanced algorithms, this book offers a rigorous yet accessible gateway into the theory and practice of approximation techniques.

Book Overview

This proceedings volume brings together 14 revised full papers and three invited contributions, carefully selected from 37 submissions presented at the workshop. The focus is squarely on the design and analysis of approximation algorithms, inapproximability results, and online problems. It covers a broad spectrum of combinatorial optimization challenges, including scheduling, routing, flow problems, coloring, partitioning, cuts, connectivity, packing, covering, geometric problems, and network design. The book serves as a snapshot of the state of the art in 1998, but its foundational concepts remain deeply relevant to modern algorithm design in India's thriving tech and academic sectors.
