The Reverse Greedy Algorithm for the Metric K-Median Problem
The Reverse Greedy algorithm (RGREEDY) for the k-median problem works as follows. It starts by placing facilities on all nodes. At each step, it removes a facility to minimize the...

Bucket Game with Applications to Set Multicover and Dynamic Page Migration
We present a simple two-person Bucket Game, based on throwing balls into buckets, and we discuss possible players’ strategies. We use these strategies to create an approximation ...

Explicit Inapproximability Bounds for the Shortest Superstring Problem
Abstract. Given a set of strings S = {s1, . . . , sn}, the Shortest Superstring problem asks for the shortest string s which contains each si as a substring. We consider two measur...

An Algorithm for Two-Dimensional Mesh Generation Based on the Pinwheel Tiling
We propose a new two-dimensional meshing algorithm called PINW able to generate meshes that accurately approximate the distance between any two domain points by paths composed onl...
