For a set Pof npoints in 茂戮驴2, the Euclidean 2-center problem computes a pair of congruent disks of the minimal radius that cover P. We extend this to the (2,k)-center problem where we compute the minimal radius pair of congruent disks to cover n茂戮驴 kpoints of P. We present a randomized algorithm with O(nk7log3n) expected running time for the (2,k)-center problem. We also study the (p,k)-center problem in 茂戮驴2under the 茂戮驴茂戮驴-metric. We give solutions for p= 4 in O(kO(1)nlogn) time and for p= 5 in O(kO(1)nlog5n) time.
