赋值约束满足问题的二值化
Binarisation for Valued Constraint Satisfaction Problems
摘要：
我们研究的方法转换值约束满足问题（VCSP）的二进制VCSP。首先，我们证明了标准的对偶编码保留了VCSP的计算复杂性的代数性质的许多方面。其次，我们将Bulin等人[LMCS'15]描述的CSP到二进制CSP的约简扩展到VCSP。这种减少建立了VCSP在一个固定值的约束语言是多项式时间等价的最小成本同态问题在一个固定的有向图。
英文摘要：
We study methods for transforming valued constraint satisfaction problems (VCSPs) to binary VCSPs. First, we show that the standard dual encoding preserves many aspects of the algebraic properties that capture the computational complexity of VCSPs. Second, we extend the reduction of CSPs to binary CSPs described by Bulin et al. [LMCS'15] to VCSPs. This reduction establishes that VCSPs over a fixed valued constraint language are polynomial-time equivalent to Minimum-Cost Homomorphism Problems over a fixed digraph.
