ON THE FORMAL SPECIFICATION AND VERIFICATION OF AUTOMATA-BASED PROGRAMS BY SPECIFICATION PATTERNS Клебанов А. А., Shalyto Anatoly Abramovich

This paper gives an overview of the research which focuses on expressing verifiable requirements in a controlled natural language in the framework of automata-based programming. Applicability of the specification patterns in scope of automata-based approach is investigated. Also a formal grammar is introduced to derivate the requirements.
