弧一致性及其朋友
Arc Consistency and Friends
摘要:
限制约束满足问题的一种自然且既定的方法是修复可用于构成约束的关系;这样的关系族称为约束语言。在这篇文章中,我们研究了弧一致性,一个大量研究的推理方法,并从约束语言的角度对其进行了三个扩展。我们进行了比较的基础上,他们解决的约束语言的研究方法,我们提出了新的多项式时间的易处理性结果单弧一致性,最强大的方法研究。
英文摘要:
A natural and established way to restrict the constraint satisfaction problem is to fix the relations that can be used to pose constraints; such a family of relations is called a constraint language. In this article, we study arc consistency, a heavily investigated inference method, and three extensions thereof from the perspective of constraint languages. We conduct a comparison of the studied methods on the basis of which constraint languages they solve, and we present new polynomial-time tractability results for singleton arc consistency, the most powerful method studied.
