A Constant–Factor Approximation Algorithm for Red–Blue Set Cover with Unit Disks

The main contribution of this paper is the first constant factor approximation algorithm for red-blue set cover problem with unit disks. To achieve this, we first give a polynomial time algorithm for line-separable red-blue set cover problem with unit disks. We next obtain a factor 2 approximation a...
