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 p log p 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+p log p-1 k) time for p=2,3. In all cases, our algorithms use O(n) space.
