Nitpick: A Counterexample Generator for Isabelle/HOL Based on the Relational Model Finder Kodkod

6 pagesPublished: March 25, 2013

Abstract

Nitpick is a counterexample generator for Isabelle/HOL that builds on Kodkod, a SAT-based first-order relational model finder. Nitpick supports unbounded quantification, (co)inductive predicates and datatypes, and (co)recursive functions. Fundamentally a finite model finder, it approximates infinite types by finite subsets. Our experimental results on Isabelle theories and the TPTP library indicate that Nitpick generates more counterexamples than other model finders for higher-order logic, without restrictions on the form of the formulas to falsify.

Keyphrases: counterexample generation, higher-order logic, interactive theorem proving, model finding
