In this paper we propose the Online Connected Facility Location problem (OCFL), which is an online version of the Connected Facility Location problem (CFL). The CFL is a combination of the Un-capacitated Facility Location problem (FL) and the Steiner Tree problem (ST). We give a randomized O(log(2) n)-competitive algorithm for the OCFL via the sample-and-augment framework of Gupta, Kumar, Pal, and Roughgarden and previous algorithms for Online Facility Location (OFL) and Online Steiner Tree (OST). Also, we show that the same algorithm is a deterministic O(log n)-competitive algorithm for the special case of the OCFL with M = 1, where M is a scale factor for the edge costs. |
