We propose a combination of Kleene’s three-valued logic and ACP process algebra via the guarded command construct. We present an operational semantics in SOS-style, and a comple...
We report on the results of a long-term project to formalize the semantics of OCL 2.0 in Higher-order Logic (HOL). The ultimate goal of the project is to provide a formalized, mach...
