小深度电路近似多数的大小界

Bounds on the Size of Small Depth Circuits for Approximating Majority

Kazuyuki Amano

摘要:

本文证明了对每个常数$0 < ε< 1/2$和$d \geq 2$,$ε$ -逼近$n$变量上的择多函数的深度$d$布尔电路的最小规模是exp $(Θ(n^{1/(2d-2)}))$ . O 'Donnell和Wimmer [ICALP'07]以前已经给出了每个$d \geq 2$的下界和$d=2$的上界,本文的贡献是给出$d \geq 3$的匹配上界。

英文摘要:

In this paper, we show that for every constant $0 < ε< 1/2$ and for every constant $d \geq 2$, the minimum size of a depth $d$ Boolean circuit that $ε$-approximates Majority function on $n$ variables is exp$(Θ(n^{1/(2d-2)}))$. The lower bound for every $d \geq 2$ and the upper bound for $d=2$ have been previously shown by O'Donnell and Wimmer [ICALP'07], and the contribution of this paper is to give a matching upper bound for $d \geq 3$.
