摘要:

本文介绍了应答集编程(ASP)中的离线调整的概念。理由提供了一个基于图形的解释原子w.r.t.的真值。给定的答案集。本文还扩展了这一概念,以提供合理的原子在计算的答案集(在线理由),并提出了一个集成的在线理由内的计算模型Smodels。离线和在线的理由提供了有用的工具,以加强对ASP的理解,他们提供了一个基本的数据结构,以支持方法和工具,调试答案集程序。已在ASP-PROGRAM中开发了一个初步实施方案。(To逻辑程序设计理论与实践(Theory and Practice of Logic Programming,TPLP)

英文摘要:

The paper introduces the notion of off-line justification for Answer Set Programming (ASP). Justifications provide a graph-based explanation of the truth value of an atom w.r.t. a given answer set. The paper extends also this notion to provide justification of atoms during the computation of an answer set (on-line justification), and presents an integration of on-line justifications within the computation model of Smodels. Off-line and on-line justifications provide useful tools to enhance understanding of ASP, and they offer a basic data structure to support methodologies and tools for debugging answer set programs. A preliminary implementation has been developed in ASP-PROLOG. (To appear in Theory and Practice of Logic Programming (TPLP))
