A Factor 3/2 Approximation for Generalized Steiner Tree Problem with Distances One and Two
Piotr Berman, Marek Karpinski and Alex Zelikovsky [Download PostScript] [Download PDF] We design a 3/2 approximation algorithm for the Generalized Steiner Tree problem (GST) in metrics with distances 1 and 2. This is the first polynomial time approximation algorithm for a wide class of non-geometric metric GST instances with approximation factor below 2. |
