N2 - Given a set P of n points in the plane, the unit disk cover problem, which is known as an NP-hard problem, seeks to find the minimum number of unit disks that can cover all points of P. We present a new 4-approximation algorithm with running time O(n log n) for this problem. Our proposed algorithm uses a simple approach and is easy to understand and implement.
