RedAlert: Determinacy Inference for Prolog

Jael Kriener and Andy King

Theory and Practice of Logic Programming, 11(4-5):182-196, July 2011.

Abstract

This paper revisits the problem of determinacy inference addressing the problem of how to uniformly handle (unknown variable cut)$. To this end a new semantics is introduced for (unknown variable cut)$, which is abstracted to systematically derive a backward analysis that derives conditions sufficient for a goal to succeed at most once. The method is conceptionally simpler and easier to implement than existing techniques, whilst improving the latter's handling of (unknown variable cut)$. Formal arguments substantiate correctness and experimental work, and a tool called 'RedAlert' demonstrates the method's generality and applicability.
