We propose an approximation algorithm for the problem of finding a maximum stable matching when both ties and unacceptable partners are allowed in preference lists. Our algorithm achieves the approximation ratio 2 -c log N/N for an arbitrarily positive constant c, where N denotes the number of men in an input. This improves the trivial approximation ratio of two. © Springer-Verlag Berlin Heidelberg 2004.
