This article describes and compares three heuristics for a variant of the Steiner tree problem with revenues, which includes budget and hop constraints. First, a greedy method which obtains good approximations in short computational times is proposed. This initial solution is then improved by means of a destroyand-repair method or a tabu search algorithm. Computational results compare the three methods in terms of accuracy and speed.
