An Almost Linear Time 2.8334-Approximation Algorithm for the Disc Covering Problem
The disc covering problem asks to cover a set of points on the plane with a minimum number of fix-sized discs. We develop an O(n(log n)2 (log log n)2 ) deterministic time 2.8334-a...

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...
