Journal ArticleDOI
A Best Possible Heuristic for the k-Center Problem
TL;DR: A 2-approximation algorithm for the k-center problem with triangle inequality is presented, the key combinatorial object used is called a strong stable set, and the NP-completeness of the corresponding decision problem is proved.
Journal ArticleDOI
Approximation schemes for covering and packing problems in image processing and VLSI
Dorit S. Hochbaum,Wolfgang Maass +1 more
TL;DR: The unified technique that is introduced here, referred to as the shifting strategy, is applicable to numerous geometric covering and packing problems and how it varies with problem parameters is illustrated.
Journal ArticleDOI
Using dual approximation algorithms for scheduling problems theoretical and practical results
TL;DR: A new approach to constructing approximation algorithms, which the aim is find superoptimal, but infeasible solutions, and the performance is measured by the degree of infeasibility allowed, which should find wide applicability for any optimization problem where traditional approximation algorithms have been particularly elusive.
Journal ArticleDOI
Approximation Algorithms for the Set Covering and Vertex Cover Problems
TL;DR: A heuristic is proposed that delivers in O(n^3 ) steps a solution for the set covering problem the value of which does not exceed the maximum number of sets covering an element times the optimal value.
Journal ArticleDOI
A polynomial approximation scheme for scheduling on uniform processors: Using the dual approximation approach
TL;DR: A family of polynomial-time algorithms are given such that the last job to finish is completed as quickly as possible and the algorithm delivers a solution that is within a relative error of the optimum.
