[PDF] Top 20 Generalised Reactive Processes in Isabelle/UTP

... R3 as presented in the UTP book and related publications is not sensitive to state, although reactive programs often need this property. Thus is is necessary to use a modification of R3 from Butterfield et ... See full document

... The first law is a homomorphism law for assignments. The other laws are corol- laries of it and the laws of Theorem 3.2. The third law, showing that assignments commute, requires an extra side condition that f does not ... See full document
