We consider the problem of finding a stable matching of maximum size when both ties and unacceptable partners are allowed in preference lists. This problem is NP-hard and the current best known approximation algorithm achieves the approximation ratio $2 - c{{\rm log N} \over {N}}$, where c is an arbitrary positive constant and N is the number of men in an input. In this paper, we improve the ratio to $2 - c{{1} \over {\sqrt{N}}}$, where c is a constant such that $c \leq {{1}\over{4\sqrt{6}}}$.
