情景演算的术语重写

Situation Calculus by Term Rewriting

UNC Chapel Hill(北卡罗来纳大学教堂山分校)

David A. Plaisted

摘要:

一个版本的情况演算中的情况表示为一阶项。流利度可以从术语结构中计算出来,并且对情境的动作对应于对术语的重写规则。在某些情况下,仅依赖于或影响流畅度子集的动作可以被描述为对术语的子术语进行操作的重写规则。如果行动是双向的,那么有效的完成方法可以用来解决规划问题。这种情况和行动的表示与Thielscher \cite{Thielscher98}的流畅演算最相似,只是这种表示更灵活,并且更多地使用了子项结构。给出了一些例子,并提出了一些一般的方法来构造这样的重写规则集。本文于2019年12月23日提交给FSCD 2020。

英文摘要:

A version of the situation calculus in which situations are represented as first-order terms is presented. Fluents can be computed from the term structure, and actions on the situations correspond to rewrite rules on the terms. Actions that only depend on or influence a subset of the fluents can be described as rewrite rules that operate on subterms of the terms in some cases. If actions are bidirectional then efficient completion methods can be used to solve planning problems. This representation for situations and actions is most similar to the fluent calculus of Thielscher \cite{Thielscher98}, except that this representation is more flexible and more use is made of the subterm structure. Some examples are given, and a few general methods for constructing such sets of rewrite rules are presented. This paper was submitted to FSCD 2020 on December 23, 2019.
