Webliterature. The classic algorithm of Dreyfus and Wagner [5] from 1971 solves Steiner Tree on general graphs in time 3n logW jV(G)jO(1), where W is the maximum edge weight in G. For Rectilinear Steiner Tree, an adaptation of Dreyfus-Wagner algorithm provides an algorithm of running time O(n2 3n).
