| Abstract(in English) | 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 (logN)/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/(N^<2/3>), where c is a constant such that c≦1/(2(√^3<6>)). |
