Different approaches in computer science involve tools (solvers) to check whether certain formulas are satisfiable. Examples can be found in the fields of hardware and software verification, counterexample generation, termination analysis of programs, and optimization algorithms, just to mention a few.
In this lecture we deal with the automatic check of satisfiability of formulas from different logics. Formulas of propositional logic can be checked for satisfiability using SAT-solvers (SAT=”satisfiability”). Extending the logic with different theories leads us to SMT-solvers (SMT=”satisfiability modulo theories”). During the semester we will discuss extensions of propositional logic with equalities, uninterpreted functions, and linear and non-linear constraints involving real- and integer-valued variables (linear/non-linear real/integer arithmetic). To demonstrate practical relevance, we employ the above methods in the context of bounded model checking.
