In this paper, we propose a new proof method for strong normalization of calculi with control operators, and, by this method, we prove strong normalization of the system
A new algorithm is presented for testing if a regular language is locally threshold testable. The new algorithm is slower than existing algorithms, but its correctness proof is sh...
In this paper an extension of the IFAD VDM-SL Toolbox with a proof obligation generator is described. Static type checking in VDM is undecidable in general and therefore the type c...
