Abstract: In this paper we propose a general methodology for solving a broad class of continuous, multifacility location problems, in any dimension and with ℓτ-norms proposing two different methodologies: (1) by a new second order cone mixed integer programming formulation and (2) by formulating a sequence of semidefinite programs that converges to the solution of the problem; each of these relaxed problems solvable with SDP solvers in polynomial time.
