In the classical minisum facility location problem, the goal is to find the placement of a new facility that minimizes the sum of weighted distances to a given set of client points. In contrast, the reverse minisum single facility location problem assumes a fixed facility location and focuses on adjusting the weights of the client points. The objective is to improve the weighted distances between the facility and clients, subject to a budget constraint on weight modifications. This paper introduces an $O(n\log n)$ algorithm for the reverse problem with variable weights, applicable to both network and continuous location models. Experimental results on diverse instances demonstrate the algorithm's effectiveness.
