研究含(抽象)约束原子逻辑程序的稳定模型语义及其性质。我们引入了这些约束原子的简洁抽象表示,其中约束原子被紧凑地表示。我们展示了两个应用程序。首先,在这种约束原子的表示下,我们推广了Gelfond-Lifschitz变换,并将其应用于任意约束原子的逻辑程序的稳定模型(也称为答案集)的定义。结果表明,所得到的语义与Son等人定义的语义一致,后者基于不动点方法。我们的方法的一个优点是,它可以以自然的方式应用于带有约束原子的析取逻辑程序定义稳定的模型,约束原子可能出现在析取头和规则的主体中。因此,我们对具有约束原子的逻辑程序的稳定模型语义的方法推广了许多以前的方法。其次,我们证明了我们对约束原子的抽象表示提供了一种刻画具有约束原子的程序中原子的依赖关系的手段,从而使过去对具有普通原子的逻辑程序的一些依赖于这些依赖关系的标准刻画和性质可以推广到具有约束原子的逻辑程序中。

分类描述:Covers all aspects of logic in computer science, including finite model theory, logics of programs, modal logic, and program verification. Programming language semantics should have Programming Languages as the primary subject area. Roughly includes material in ACM Subject Classes D.2.4, F.3.1, F.4.0, F.4.1, and F.4.2; some material in F.4.3 (formal languages) may also be appropriate here, although Computational Complexity is typically the more appropriate subject area.

英文摘要:
  This paper studies the stable model semantics of logic programs with (abstract) constraint atoms and their properties. We introduce a succinct abstract representation of these constraint atoms in which a constraint atom is represented compactly. We show two applications. First, under this representation of constraint atoms, we generalize the Gelfond-Lifschitz transformation and apply it to define stable models (also called answer sets) for logic programs with arbitrary constraint atoms. The resulting semantics turns out to coincide with the one defined by Son et al., which is based on a fixpoint approach. One advantage of our approach is that it can be applied, in a natural way, to define stable models for disjunctive logic programs with constraint atoms, which may appear in the disjunctive head as well as in the body of a rule. As a result, our approach to the stable model semantics for logic programs with constraint atoms generalizes a number of previous approaches. Second, we show that our abstract representation of constraint atoms provides a means to characterize dependencies of atoms in a program with constraint atoms, so that some standard characterizations and properties relying on these dependencies in the past for logic programs with ordinary atoms can be extended to logic programs with constraint atoms.
