Abstract

Constraint logic programming languages extend logic programming by providing constraint solving capabilities on particular domains, which are more powerful than normal unification. However, these capabilities are usually general-purpose and embedded in the language. In this paper we make a case for extending the user interaction with the constraint solver, namely to achieve better performances. More specifically we present for finite domains, an inference rule (SLAIR) which subsumes previously defined ones and improves their interactivity. Additionally, experimental results show that this rule leads to significant speedup in execution time.
