WebAbstract. Given an undirected graph G with a cost function on vertices, a collection of subgraphs of G such that in each subgraph, there are some distinguished vertices called terminals, the Partitioned Steiner Tree Problem (PSTP) asks for a minimum cost vertex set such that, in each of the given subgraph G i, the graph induced by the vertex set spans … Web1 de mai. de 1978 · Bell System interest in the Steiner problem comes from the fact that, other things being equal, Steiner minimal networks are good candidates for routes for new broadband connection channels.
