The problem is shown to be strongly NP{mathcal{NP}}-hard on general graphs and weakly NP{mathcal{NP}}-hard on series-parallel graphs. Therefore, the special case on a tree is considered: It is shown that the inverse 2-median problem with variable edge lengths on trees is solvable in ...
The P-Median Problem is one of the basic cases of facility location problems and has been studied for many years. Most methods of solving it are based on classical heuristics or meta-heuristic and they don't perform well on large-scale problems according to time cost. In this paper, we ...
