An Efficient Approximation Algorithm for the Steiner Tree Problem,oposed an interactive method that achieves an approximation ratio of .. Moreover, Goemans .. shown that it is possible to achieve the same approximation guarantee while only solving hypergraphic LP relaxation once. However, solving hypergraphic LP relaxation is time consuming. This article presents
