超立方体上布尔函数的o(n)单调性检验

A o(n) monotonicity tester for Boolean functions over the hypercube

Deeparnab Chakrabarty, C. Seshadhri

摘要:

布尔函数$f:\{0,1\}^n \mapsto \{0,1\}$被称为$\eps$ -远离单调,如果$f$需要在至少$\eps$ -分数的点中被修改以使其单调。我们设计了一个随机测试器,它被赋予对$f$的Oracle访问和输入参数$\eps>0$,并且具有以下保证:如果函数是单调非减的,则输出{\sf Yes};如果函数是$\eps$ -远离单调的,则输出{ \sf No},概率为$>2/3$。该非自适应、单侧测试仪对oracle进行$O(n^{7/8}\eps^{-3/2}\ln(1/\eps))$查询。

英文摘要:

A Boolean function $f:\{0,1\}^n \mapsto \{0,1\}$ is said to be $\eps$-far from monotone if $f$ needs to be modified in at least $\eps$-fraction of the points to make it monotone. We design a randomized tester that is given oracle access to $f$ and an input parameter $\eps>0$, and has the following guarantee: It outputs {\sf Yes} if the function is monotonically non-decreasing, and outputs {\sf No} with probability $>2/3$, if the function is $\eps$-far from monotone. This non-adaptive, one-sided tester makes $O(n^{7/8}\eps^{-3/2}\ln(1/\eps))$ queries to the oracle.
