Forward Reasoning via Sequential Queries in Logic Programming

Keehang Kwon

Abstract

Most Prolog implementations are based on backward chaining techniques. However, there are many applications in which forward chaining ones are desirable such as in dynamic programming. In this paper, we first introduce a variant of a Prolog interpreter that computes interpolations and then introduce the notion of sequential queries. These two notions allow a combination of both forms of reasoning in Prolog.DOI: http://dx.doi.org/10.5755/j01.itc.41.4.2364
