As shown in the figure, this is a code example that defines the data types and fun functions of the source and target models in the model transformati ...

On Dafny, a lemma is implemented as a ghost method, thus, it is only useful for the specification. However, you cannot call a lemma from a ghost fiel ...

I have been reading about formal verification and the basic point is that it requires a formal specification and model to work with. However, many sou ...
