Abstract
We study the Set Cover, Hitting Set, Piercing Set, Independent Set, Dominating Set problems, and discrete versions (Discrete Independent Set and Discrete Dominating Set) for geometric instances in the plane. We focus on certain restricted classes of geometric objects, including axis-parallel lines, strips, and rectangles. For rectangles, we consider the cases in which the rectangles are (i) anchored on a horizontal line, (ii) anchored on two lines (either two parallel lines or one vertical and one horizontal line), and (iii) stabbed by a horizontal line. Some versions of these problems have been studied previously; we focus here on the open cases, for which no complexity results were known.
