Facility location problem algorithm
WebWe introduce a facility location problem with submodular facility cost functions, and give an O(log n) approximation algorithm for it. Then we focus on a special case of submodular costs, called hierarchical facility costs, and give a (4.237 + ϵ)-... WebThe p-center problem is finding the location of p facilities among a set of n demand points such that the maximum distance between any demand point and its nearest facility is minimized.
