Z3 is an automated theorem prover and satisfiability modulo theories (SMT) solver. Given a formula in first-order logic, it attempts to either prove the formula or find a counterexample. Z3 supports arithmetic, reasoning about arrays, and several other built-in theories. Input problems are written in SMT-LIB format. This package includes the z3 program as well as the C++ and Python APIs. By default the Python 2 version of the API is built; if you also want the Python 3 version, run the SlackBuild with PYTHON3=yes, like so: PYTHON3=yes ./z3.SlackBuild
