A 1.488 Approximation Algorithm for the Uncapacitated Facility Location Problem
We present a 1.488 approximation algorithm for the metric uncapacitated facility location (UFL) problem. The previous best algorithm was due to Byrka [1]. By linearly combining two algorithms A1(γf ) for γf = 1.6774 and the (1.11,1.78)-approximation algorithm A2 proposed by Jain, Mahdian and Saberi [8], Byrka gave a 1.5 approximation algorithm for the UFL problem. We show that if γf is randomly...

متن کاملA Distributed Approximation Algorithm for the Metric Uncapacitated Facility Location Problem in the Congest Model
We present a randomized distributed approximation algorithm for the metric uncapacitated facility location problem. The algorithm is executed on a bipartite graph in the CONGEST model yielding a (1.861+ ε) approximation factor, where ε is an arbitrary small positive constant. It needs O(n3/4 log1+ε(n)) communication rounds with high probability (n denoting the number of facilities and clients)....
متن کاملA 3-Approximation Algorithm for the k-Level Uncapacitated Facility Location Problem
In the k-level uncapacitated facility location problem, we have a set of demand points where clients are located. The demand of each client is known. Facilities have to be located at given sites in order to service the clients, and each client is to be serviced by a sequence of k different facilities, each of which belongs to a distinct level. There are no capacity restrictions on the facilitie...
متن کاملMemetic Algorithm for Solving the Multilevel Uncapacitated Facility Location Problem
We consider the Multilevel Uncapacitated Facility Location Problem (MLUFLP) and propose a new efficient integer programming formulation of the problem that provides optimal solutions for theMLUFLP test instances unsolved to optimality up to now. Further, we design a parallel Memetic Algorithm (MA) with a new strategy for applying the local search improvement within the MA frame. The conducted c...
