Summary
| Description |
日本語: 直交配列 OA(N, k, s, t) は s 種類の要素を成分に持つ N × k 行列で、どの t 列を取り出しても要素 s 種類からなる全ての t-タプル が等しく N/(s^t) 回ずつ行として現れる配列です。
この図の右側に挙げた OA(18, 7, 3, 2) では、どの2列を取り出しても、3種類の文字の順序対、つまり、(1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3) の9つ全てが等しく2回ずつ行として現れていることが確認できます。
English: An orthogonal array OA(N, k, s, t) is an N × k matrix with s kinds of elements as components such that each t-tuple of the elements are contained same times as a row in any N × t subarray constructed by taking t columns.
In this image, for OA(18, 7, 3, 2) on the right side, you can see that every 18 × 2 subarray on the left side contains each 2-tuple twice as a row. |
