A tabu search approach to the uncapacitated facility location problem

In this paper, the uncapacitated facility location problem is considered. A tabu search algorithm for solving this problem is proposed. The algorithm is tested on some standard test problems taken from literature and its performance is compared with the known optimal solutions. Computational results show that the proposed algorithm produces optimal solutions for all test problems, and that it is very efficient in terms of time compared to existing algorithms in the literature.
