The w-centroid problem, denoted by (C), is an optimization problem which has been shown by Kariv and Hakimi to be equivalent, on a tree graph, to the 1-median location problem, denoted by (M). For a general (weighted) connected graph G we develop a duality between (C) (which is defined on G) and a b
