显式非自适应组合成组测试方案

Explicit Non-Adaptive Combinatorial Group Testing Schemes

Ely Porat, Amir Rothschild

摘要:

分组测试是组合学中一个研究已久的问题:一小组$r$病人应该从整个($n$人)中识别出来,只使用形式为“集合X是否包含一个病人?".在本文中,我们提供了一个明确的建设的测试计划,这是更好(更小)比任何已知的明确建设。该方案具有与最好的非显式方案一样多的$\bigT{\min[r^2 \ln n,n]}$测试。在我们的构造中,我们使用了一个可能具有自身价值的事实:参数$[m,k,δm]_q$满足Gilbert-Varshamov界的线性纠错码可以在$\bigT{q^km}$时间内非常有效地构造。

英文摘要:

Group testing is a long studied problem in combinatorics: A small set of $r$ ill people should be identified out of the whole ($n$ people) by using only queries (tests) of the form "Does set X contain an ill human?". In this paper we provide an explicit construction of a testing scheme which is better (smaller) than any known explicit construction. This scheme has $\bigT{\min[r^2 \ln n,n]}$ tests which is as many as the best non-explicit schemes have. In our construction we use a fact that may have a value by its own right: Linear error-correction codes with parameters $[m,k,δm]_q$ meeting the Gilbert-Varshamov bound may be constructed quite efficiently, in $\bigT{q^km}$ time.
