一个约束满足问题的算法被称为鲁棒的,如果它输出的分配满足至少(1-g(ε))-分数的约束给定的(1-ε)-可满足的情况下,其中g(ε)-> 0作为ε -> 0,$g(0)=0。Guruswami和Zhou推测了约束语言的一个特征,其中相应的约束满足问题需要一个高效的鲁棒算法。这篇论文证实了他们的猜想。
An algorithm for a constraint satisfaction problem is called robust if it outputs an assignment satisfying at least (1-g(ε))-fraction of the constraints given a (1-ε)-satisfiable instance, where g(ε) -> 0 as ε -> 0, $g(0)=0. Guruswami and Zhou conjectured a characterization of constraint languages for which the corresponding constraint satisfaction problem admits an efficient robust algorithm. This paper confirms their conjecture.
