At first we consider partial correctness only, and discuss Reynolds’ method and a partial correctness version of VDM. Later we also consider total correctness in order to cover (part of) Back’s refinement calculus and the full notion

An object’s behaviour must fall within the framework set by the environment but subject to the possibilities determined by its class. Intuitively, class refinement will lead to some kind of behavioural compatibility; hence a theory of cl

The three stages entail interpreting equalities as behavioural equivalences, converting functions into procedures, and replacing axioms by programs. The stages can be performed as automatic transformations which

The choice was motivated by a desire to expand the set of example refinements and to show how algorithms in this area may be formally derived from their specifications. The ultimate
