Abstract

We show that rewrite systems can be used to give semantics to imperative programs with boolean variables, a class of programs used in software model-checking as over- or underapproximations of real programs. We study the classes of rewrite systems induced by programs with different features like procedures, concurrency, or dynamic thread creation, and survey a number of results on their word problem and their symbolic reachability problem.
