Abstract
For a set of n points in the plane, we consider the axis–aligned (p,k)-Box Covering problem: Find p axis-aligned, pairwise disjoint boxes that together contain exactly n − k points. Here, our boxes are either squares or rectangles, and we want to minimize the area of the largest box. For squares, we present algorithms that find the solution in O(n + klogk) time for p = 1, and in O(nlogn + k plogp k) time for p = 2,3. For rectangles we have running times of O(n + k 3) for p = 1 and O(nlogn + k 2 + plogp − 1 k) time for p = 2,3. In all cases, our algorithms use O(n) space.
