The un-capacitated facility location (UFL) problem is a classical combinatorial optimization hard problem and has been applied in various fields. The semi-Lagrangian relaxation method is one of the exact solution methods to the UFL. In this paper, the mathematical nature of the SLR applied to solve the UFL is further studied. Based on this, the SLR applied to solve the UFL is improved from the theoretical point of view, and the approach is also discussed to enhance its
computational capability. The numerical results show that the improvement proposed in this paper is feasible and effective.
