研究一个含有1个n-2圈和3个n-3圈的n阶本原有向图.通过分析本原图中任一点经过k长的途径所到达的顶点的集合,利用m-competition指数定义,确定了本原图的m-competition指数.
A primitive digraph of order n with one(n-2)-cycle and three(n-3)-cycles was discussed.By analysing the sets of vertexes,which are formed by each vertex passing a walk of lengthk in the primitive digraph and according to the definition of m-competition index,the m-competition index of the primitive digraph was obtained.
