    Specifications of state machines in CafeOBJ are called equational theory specifications (EQT Specs) which are based on equational logic, and in Maude are called rewrite theory specifications (RWT Specs) which are based on rewriting logic. The translation from EQT Specs to RWT Specs achieves the collaboration between CafeOBJ’s theorem proving facilities and Maude’s model checking facilities. However, translated specifications by existing strategies are of inefficiency and rarely used for model checking in practice. This paper defines a specific class of EQT Specs called EADS Specs, and proposes a strategy for the translation from EADS Specs to RWT Specs. It is proved that translated specifications by the strategy are more efficient than those by existing strategies

    Twenty years of rewriting logic

    AbstractRewriting logic is a simple computational logic that can naturally express both concurrent computation and logical deduction with great generality. This paper provides a gentle, intuitive introduction to its main ideas, as well as a survey of the work that many researchers have carried out over the last twenty years in advancing: (i) its foundations; (ii) its semantic framework and logical framework uses; (iii) its language implementations and its formal tools; and (iv) its many applications to automated deduction, software and hardware specification and verification, security, real-time and cyber-physical systems, probabilistic systems, bioinformatics and chemical systems
