Résumé :
We discuss different approaches to solving constraints within the Isabelle framework. Our motivation are constraint problems arising in the HOL-TestGen tool for test generation. We explore possibilities of exploiting counterexamples returned by SMT solvers for constructing solutions to constraints in Isabelle. A particular challenge are constraints that involve recursive functions. We show how the rich support for interaction provided by Isabelle can be used to enlarge the class of constraints that can be handled.
