Abstract

In Online Facility Location, demands arrive online and must be irrevocably assigned to an open facility upon arrival. The objective is to minimize the sum of facility and assignment costs.


We present a deterministic algorithm which achieves an asymptotically optimal competitive ratio for this problem.
