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 $2-c\frac{\log N}{N}$, 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 $2-c\frac{1}{N^\frac{2}{3}}$, where $c$ is a constant such that $c \leq \frac{1}{2 \sqrt[3]{6}}$. |
