Abstract
We consider new versions of the two-center problem where the input consists of a set \(\mathcal{D}\) of disks in the plane. We first study the problem of finding two smallest congruent disks such that each disk in \(\mathcal{D}\) intersects one of these two disks. Then we study the problem of covering the set \(\mathcal{D}\) by two smallest congruent disks. We give exact and approximation algorithms for these versions.
