In this paper, we present a new mathematical programming formulation for the euclidean Steiner Tree Problem (ESTP) in ℜ n . We relax the integrality constrains on this formulation and transform the resulting relaxation, which is convex, but not everywhere differentiable, into a standard convex programming problem in conic form. We consider then an efficient computation of an ϵ-optimal solution for this latter problem using interior-point algorithm.

Keywords: euclidean Steiner tree problem, conic form, interior point algorithms
