heal.abstract |
In the online version of Facility Location, the demand points arrive one at a time 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 simple deterministic primal-dual algorithm for the general case of non-uniform facility costs. We prove that its competitive ratio is |
