二階投影平面架構能提供最好的群試設計----對七物件及最多兩感染物而論

A projective plane of order 2 offers the best group tests----for 7 items and at most 2 defectives

指導教授 : 翁志文

摘要


我們證明一個由二階投影平面的關係矩陣,刪去一列所得到大小為6乘以7的二元矩陣其分離性為二。我們同時證明不存在分離性為二,行數小於七,列數小於六的二元矩陣。

並列摘要


We prove that the matrix obtained by deleting a row of the incidence matrix of the projective plane of order 2 is 2-separable. We also prove that there is no 2-separable s×t matrix with s< t< 7.
