查询词典 combinatorial problem

On the basis of common GM(1,1) model and by means of establishing residual error periodic extensional model, the authors extract predominant period and reconstruct a new data sequence; then after superposing the values of the same time in different period, a ray-periodic extensional combinatorial model is built.

提出了灰色–周期外延组合模型，即在一般灰色模型GM(1，1)的基础上建立残差周期外延模型，并提取优势周期以重新构造新的数据序列，再将不同周期同一时刻的值叠加。

The orbits of the point stabilizer of a finite permutation group are called the suborbits of the permutation group. The determination of the suborbits of a permutation group is one of the basic problems in the permutation group theory. It plays an important role in the study of combinatorial structures.
