Online Hitting Set for Axis-Aligned Squares
Minati De, Satyam Singh, Csaba D. Tóth
We are given a set of points in the plane, and a sequence of axis-aligned squares that arrive in an online fashion. The online hitting set problem consists of maintaining,…
Online Hitting Sets for Disks of Bounded Radii
Minati De, Satyam Singh, Csaba D. Tóth
We present algorithms for the online minimum hitting set problem in geometric range spaces: given a set of points in the plane and a sequence of geometric objects that arri…
Online Geometric Hitting Set and Set Cover Beyond Unit Balls in
Minati De, Ratnadip Mandal, Satyam Singh
We investigate the geometric hitting set problem in the online setup for the range space , where the set is a collection of poin…
New Lower Bound and Algorithms for Online Geometric Hitting Set Problem
Minati De, Ratnadip Mandal, Satyam Singh
The hitting set problem is one of the fundamental problems in combinatorial optimization and is well-studied in offline setup. We consider the online hitting set problem, where onl…
