论文摘要
近似固定点理论(AFT)是研究非单调逻辑语义的抽象和一般代数框架。它提供了针对非单调推理的不同形式主义语义的统一研究,例如逻辑编程,默认逻辑和自身皮病逻辑。在本文中,我们将其扩展到处理允许处理无限信息的非确定性构造,例如通过析取公式。这是通过将AFT的主要结构和相应结果推广到非确定性运算符的,其范围是元素的集合,而不是单个元素。这种概括的适用性和实用性在分离逻辑编程的背景下说明了。
Approximation fixpoint theory (AFT) is an abstract and general algebraic framework for studying the semantics of nonmonotonic logics. It provides a unifying study of the semantics of different formalisms for nonmonotonic reasoning, such as logic programming, default logic and autoepistemic logic. In this paper, we extend AFT to dealing with non-deterministic constructs that allow to handle indefinite information, represented e.g. by disjunctive formulas. This is done by generalizing the main constructions and corresponding results of AFT to non-deterministic operators, whose ranges are sets of elements rather than single elements. The applicability and usefulness of this generalization is illustrated in the context of disjunctive logic programming.
