| 摘要: |
| 本文提出一种新的基于抽象解释的逻辑程序部分演绎方法．在一遍预处理里，针对给定的程序Ｐ和目标Ｇ，同时进行Ｐ∪｛Ｇ｝的部分演绎和抽象解释，以抽象解释控制部分演绎的展开过程．只要抽象论域是有穷的，部分演绎必定终止，而且Ｐ＇带有抽象解释估算出的关于其运行性质的信息，便于对Ｐ作进一步优化． |

| A PARTIAL DEDUCTION PROCEDURE BASED ON Abstract INTERPRETATIONS |

| Abstract: |
| This paper presents a novel approach to partial deduction (PD) of logic programming,which is based on abstract interpretations (AIs).In asingle preprocessing phase,given a program P and a goal G, PD and AI for P ∪ {G} are carried out simultaneously,with AI controlling the process of auto-unfolding in PD. PD always terminates if the abstract domain of AI is finite. Moreover, P' has got the information (collected by AI) about its operationalbehavior, which can be used for further optimization of P'. |
