On the line-separable unit-disk coverage and related problems

G Liu, H Wang - Computational Geometry, 2024 - Elsevier
Given a set P of n points and a set S of m disks in the plane, the disk coverage problem asks
for a smallest subset of disks that together cover all points of P. The problem is NP-hard. In …
