Web1 de jul. de 2005 · Network design problems, such as generalizations of the Steiner Tree Problem, can be cast as edge-cost-flow problems. An edge-cost flow problem is a min-cost flow problem in which the cost of the flow equals the sum of the costs of the edges carrying positive flow.We prove a hardness result for the Minimum Edge Cost Flow … Webvalue of the Steiner tree problem [14]. The Steiner tree problem on a graph G = (V, E) can be transformed into a Steiner arborescence problem by considering the digraph DG = (V, A) obtained by bi- directing every edge of G, choosing arbitrarily a root vertex r E T and defining the cost of the arc (i, j) E A by cij = I, where e = {i, j}.
