自适应和非自适应性能测试器之间的近二次差距

A Nearly-Quadratic Gap Between Adaptive and Non-Adaptive Property Testers

Jeremy Hurwitz

摘要:

我们发现,对于所有整数$t\geq 8$和任意小的$ε>0$,存在一个图形属性$Π$(这取决于$ε$),$ε$测试$Π$具有非自适应查询复杂度$Q=\~Θ(q^{2-2/t})$,其中$q=\~Θ(ε^{-1})$是自适应查询复杂度。这解决了在邻近依赖属性(\cite{benefits-of-adaptivity})的上下文中自适应性有多有益的问题。这也证明了Goldreich和Trevisan(\cite{canonical-testers})的规范转换在将自适应特性测试仪转换为非自适应特性测试仪时本质上是最优的。为了做到这一点,我们提供了最佳的自适应和非自适应测试的组合属性,具有最大程度的$O(εN)$,是一个\emph{blow-up collection}的任意基图$H$。

英文摘要:

We show that for all integers $t\geq 8$ and arbitrarily small $ε>0$, there exists a graph property $Π$ (which depends on $ε$) such that $ε$-testing $Π$ has non-adaptive query complexity $Q=\~Θ(q^{2-2/t})$, where $q=\~Θ(ε^{-1})$ is the adaptive query complexity. This resolves the question of how beneficial adaptivity is, in the context of proximity-dependent properties (\cite{benefits-of-adaptivity}). This also gives evidence that the canonical transformation of Goldreich and Trevisan (\cite{canonical-testers}) is essentially optimal when converting an adaptive property tester to a non-adaptive property tester. To do so, we provide optimal adaptive and non-adaptive testers for the combined property of having maximum degree $O(εN)$ and being a \emph{blow-up collection} of an arbitrary base graph $H$.
