摘要:

传统的选言组测试模型假设在一个大的群体中有几个有缺陷的元素(或缺陷),并且当且仅当测试组包含至少一个有缺陷的元素时,组测试才产生阳性响应。基本问题是使用尽可能少的组测试来找到所有缺陷。然而,当缺陷的数量是未知的,出现了一个额外的问题,即:如何估计的随机数的缺陷元素。在本文中,我们专注于测试假设$H_0$:缺陷$\le s_1$的数量与备择假设$H_1$:缺陷$\ge s_2$的数量。我们引入了一种新的解码算法的基础上的测试有积极的反应与适当的固定阈值的数量进行比较。对于$s_1$和$s_2$上的某些渐近区域,该算法是阶最优的.此外,我们的仿真结果验证了所提出的算法的优点,如低复杂度和小的错误概率与已知的算法相比。

英文摘要:

The conventional model of disjunctive group testing assumes that there are several defective elements (or defectives) among a large population, and a group test yields the positive response if and only if the testing group contains at least one defective element. The basic problem is to find all defectives using a minimal possible number of group tests. However, when the number of defectives is unknown there arises an additional problem, namely: how to estimate the random number of defective elements. n this paper, we concentrate on testing the hypothesis $H_0$: the number of defectives $\le s_1$ against the alternative hypothesis $H_1$: the number of defectives $\ge s_2$. We introduce a new decoding algorithm based on the comparison of the number of tests having positive responses with an appropriate fixed threshold. For some asymptotic regimes on $s_1$ and $s_2$, the proposed algorithm is shown to be order-optimal. Additionally, our simulation results verify the advantages of the proposed algorithm such as low complexity and a small error probability compared with known algorithms.
