成组测试算法:界限和模拟

Group testing algorithms: bounds and simulations

Matthew Aldridge, Leonardo Baldassini, Oliver Johnson

摘要:

我们考虑$K$有缺陷的$N$项目的非自适应无噪声组测试问题。我们描述了四种检测算法:Chan等人的COMP算法;两个新的算法,DD和SCOMP,这需要更强的证据来宣布一个项目有缺陷;和一个基本上是最佳的,但计算困难的算法称为SSS。通过考虑这些算法与伯努利设计的渐近速率,我们看到DD优于COMP,DD在$K \geq \sqrt N$的情况下基本上是最优的,并且当$K > N^{0.35}$时,没有一个非自适应伯努利设计的算法可以执行得和最好的非随机自适应设计一样好。在模拟中,我们看到DD和SCOMP远远优于COMP,SCOMP非常接近最佳SSS,特别是在$K$较大的情况下。

英文摘要:

We consider the problem of non-adaptive noiseless group testing of $N$ items of which $K$ are defective. We describe four detection algorithms: the COMP algorithm of Chan et al.; two new algorithms, DD and SCOMP, which require stronger evidence to declare an item defective; and an essentially optimal but computationally difficult algorithm called SSS. By considering the asymptotic rate of these algorithms with Bernoulli designs we see that DD outperforms COMP, that DD is essentially optimal in regimes where $K \geq \sqrt N$, and that no algorithm with a nonadaptive Bernoulli design can perform as well as the best non-random adaptive designs when $K > N^{0.35}$. In simulations, we see that DD and SCOMP far outperform COMP, with SCOMP very close to the optimal SSS, especially in cases with larger $K$.
