Given a weighted graph and a subset R of its vertices, the Steiner tree asks for a minimum-cost tree that connects the vertices in R. We discuss a new LP-based approximation algorithm by Byrka, Grandoni, Rothvoß and Sanità which improves the approximation ratio from 1.55 to 1.39 and introduces the method of randomized iterative rounding.
