只读布尔公式通信复杂性的深度无关下界

Depth-Independent Lower bounds on the Communication Complexity of Read-Once Boolean Formulas

Rahul Jain, Hartmut Klauck, Shengyu Zhang

摘要:

我们证明了$Ω(\sqrt{n})$和$Ω(n^{1/4})$的随机和量子通信复杂性度的下界,分别为所有$n$变量只读一次布尔公式。我们的结果补充了最近的下界$Ω(n/8^d)$由Leonardos和Saks和$Ω(n/2^{Ω(d\log d)})$由Jayram,Kopparty和Raghavendra的只读一次布尔公式的深度$d$的随机通信复杂性。我们通过在任何给定的只读布尔公式中“嵌入”不相交性问题或其补充来获得我们的结果。

英文摘要:

We show lower bounds of $Ω(\sqrt{n})$ and $Ω(n^{1/4})$ on the randomized and quantum communication complexity, respectively, of all $n$-variable read-once Boolean formulas. Our results complement the recent lower bound of $Ω(n/8^d)$ by Leonardos and Saks and $Ω(n/2^{Ω(d\log d)})$ by Jayram, Kopparty and Raghavendra for randomized communication complexity of read-once Boolean formulas with depth $d$. We obtain our result by "embedding" either the Disjointness problem or its complement in any given read-once Boolean formula.
