多方通信复杂性中NP和coNP的分离

A Separation of NP and coNP in Multiparty Communication Complexity

Dmytro Gavinsky, Alexander A. Sherstov

摘要:

本文证明了在至多k =(1-ε)log(n)个局中的多方通信复杂性额上数模型中,NP不同于coNP,coNP不是MA的子集,其中ε> 0是任意常数.具体地说,我们构造了一个函数F,它的非确定性复杂度为O(log(n)),Merlin-Arthur复杂度为n ^{Ω(1)}。这个问题对于k> 2是开放的。

英文摘要:

We prove that NP differs from coNP and coNP is not a subset of MA in the number-on-forehead model of multiparty communication complexity for up to k = (1-ε)log(n) players, where ε>0 is any constant. Specifically, we construct a function F with co-nondeterministic complexity O(log(n)) and Merlin-Arthur complexity n^{Ω(1)}. The problem was open for k > 2.
