Formal verification with the OTS/CafeOBJ method
The OTS/CafeOBJ method is a modeling, specification and verification method for systems. Observational transition systems, or OTSs are used as mathematical models of systems. OTSs are written in CafeOBJ, an algebraic specification language/system, and it is verified that OTSs satisfy properties by writing proof plans called proof scores in CafeOBJ and checking them with CafeOBJ.
