广义Lovasz局部引理的构造性证明

A constructive proof of the general Lovasz Local Lemma

Robin A. Moser, Gábor Tardos

摘要:

Lovasz局部引理[EL75]是一个强有力的工具,可以非构造性地证明满足规定标准集合的组合对象的存在性。在他的突破性论文[Bec91]中,贝克证明了在某些更严格的条件下可以给出一个建设性的变体。随后在几篇出版物[Alo91、MR98、CS00、Mos06、Sri08、Mos08]中展示了他的手术简化和限制放宽。在[Mos09]中,提出了一个在可忽略的限制下工作的构造性证明,该证明是根据有界发生可满足性问题制定的。在本文中,我们重新制定和改进这些发现,以便直接适用于几乎所有已知的应用程序的一般局部引理。

英文摘要:

The Lovasz Local Lemma [EL75] is a powerful tool to non-constructively prove the existence of combinatorial objects meeting a prescribed collection of criteria. In his breakthrough paper [Bec91], Beck demonstrated that a constructive variant can be given under certain more restrictive conditions. Simplifications of his procedure and relaxations of its restrictions were subsequently exhibited in several publications [Alo91, MR98, CS00, Mos06, Sri08, Mos08]. In [Mos09], a constructive proof was presented that works under negligible restrictions, formulated in terms of the Bounded Occurrence Satisfiability problem. In the present paper, we reformulate and improve upon these findings so as to directly apply to almost all known applications of the general Local Lemma.
