Abstract

Let P be a set of points in the plane. The goal is to place two unit disks in the plane such that the number of points from P covered by the disks is maximized. In addition, the distance between the centers of the two disks should not exceed a specified constant Rc ≥ 0. We propose two algorithms to solve this problem. The first algorithm is a simple exhaustive algorithm which runs in O(n4) time. We then improve this algorithm by a constructing connectivity region and building a segment tree to compute two optimal disks. The resulting algorithm has \(O(n^{3} \log n)\) time complexity.

For the cases that the graph is not connected, it can be connected by adding some extra edges between connected sub-graphs.
