SMTInterpol is an SMT Solver that can compute Craig interpolants for various theories. The solver is developed at the Chair of Software Engineering at the University of Freiburg.

The solver is written in Java and can be used on any operating system that supports Java Version 8 or above.

The solver reads input in SMTLIB Version 2.6 format.

The current version of SMTInterpol supports the combination of the theories of uninterpreted functions, linear real arithmetic, linear integer arithmetic, arrays including constant arrays, and datatypes.

SMTInterpol supports quantifiers for all supported theories except for datatypes, and it supports interpolation for the quantifier-free fragments of all supported theories except datatypes.

SMTInterpol needs a Java 8 JRE or above. No special hardware is necessary but depending on the input problem, a fast CPU and a good amount of RAM might be useful.

SMTInterpol is developed by Jochen Hoenicke in the context of the project "Quantified Formulas in Interpolating SMT Solvers" and by Elisabeth Henkel and Tanja Schindler. If you have any questions, suggestions, or if you want to contribute, feel free to contact us.

SMTInterpol is distributed under LGPL Version 3.

SMTInterpol participates regularly in the SMT-COMP. See this page or the news page for further details.
