Abstract. It has often been claimed that model checking, special purpose automated deduction or interactive theorem proving are needed for formal program development. Recently, it has been demonstrated that off-the-shelf automated proof and counterexample search is an interesting alternative if combined with the right domain model. Furthermore it has been shown that variants of Kleene algebra might provide light-weight formal methods with heavy-weight automation. In this paper we give a brief overview of a number of program analysis and computer mathematics tasks where (variants of) Kleene algebra combined with automated theorem provers is already applied.
