On Some Problem of the Score-vector of a Double-arc Tournament

给出了双弧竞赛图的若干类型的得分向量的计数问题 ;

A competition where n participants play each other just once and where,the ties are allowed,can be interpreted as a double arc tournament.In this paper we discuss the problem of the enumeration of some classes of score vectors.The relation between the numbers of tournaments and double arc tournaments is also established.
