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}. Web1 de jan. de 1987 · The Prize-collecting Steiner Tree Problem (PCSTP) is a well-known problem in graph theory and combinatorial optimization. It has been successfully applied to solve real problems such as fiber-optic and gas distribution networks design. In this work, we concentrate on its application in biology to perform a functional analysis of genes.
