Before revision:  Given a set of points P in the plane, the classic Unit Covering (UC) problem asks to compute the minimum number of unit disks (possibly intersecting) required to cover the points in P, along with a placement of the disks .
After revision: We revisit the online Unit Covering problem in higher dimensions: Given a set of points P in the plane, the classic Unit Covering (UC) problem asks to compute the minimum number of unit disks (possibly intersecting) required to cover the points in P, along with a placement of the disks .
