3缺陷的最优多阶段成组测试算法

Optimal Multistage Group Testing Algorithm for 3 Defectives

Ilya Vorobyev

摘要:

组测试是一个众所周知的搜索问题,它包括通过对适当选择的样本子集进行测试来检测一组$t$样本中的$s$缺陷成员。在经典的成组测试中,目标是在最坏的情况下使用尽可能少的测试次数来找到所有有缺陷的元素。在这项工作中,一个多级组测试问题被认为是。我们的目标是构建一个多阶段的搜索过程,具有渐近相同数量的测试的最佳自适应算法。我们提出了一种新的方法来设计多级算法,这使我们能够构建一个5阶段的算法,找到3个缺陷的最佳数量$3\log_2t(1+o(1))$的测试。

英文摘要:

Group testing is a well-known search problem that consists in detecting of $s$ defective members of a set of $t$ samples by carrying out tests on properly chosen subsets of samples. In classical group testing the goal is to find all defective elements by using the minimal possible number of tests in the worst case. In this work, a multistage group testing problem is considered. Our goal is to construct a multistage search procedure, having asymptotically the same number of tests as the optimal adaptive algorithm. We propose a new approach to designing multistage algorithms, which allows us to construct a 5-stage algorithm for finding 3 defectives with the optimal number $3\log_2t(1+o(1))$ of tests.
