关于平面值CSP

On Planar Valued CSPs

Peter Fulla, Stanislav Zivny

摘要:

研究了平面值约束满足问题(VCSPs)的计算复杂性,这类问题要求实例的关联图是平面的。首先,我们证明了,棘手的布尔VCSPs必须是自互补的是在平面设置易处理,从而扩展了相应的结果Dvorak和Kupec [ICALP'15]从CSP VCSPs。其次,我们给出了任意有限域上保守平面VCSP的完全复杂性分类。在这种情况下,平面性不会导致任何新的易于处理的情况,因此我们的分类是Kolmogorov和Zivny [JACM'13]保守VCSP分类的锐化。

英文摘要:

We study the computational complexity of planar valued constraint satisfaction problems (VCSPs), which require the incidence graph of the instance be planar. First, we show that intractable Boolean VCSPs have to be self-complementary to be tractable in the planar setting, thus extending a corresponding result of Dvorak and Kupec [ICALP'15] from CSPs to VCSPs. Second, we give a complete complexity classification of conservative planar VCSPs on arbitrary finite domains. In this case planarity does not lead to any new tractable cases and thus our classification is a sharpening of the classification of conservative VCSPs by Kolmogorov and Zivny [JACM'13].
