Conservative fixpoint functions on a graph,e not new, but the calculational, abstract and compact technique of deriving them is meant to improve and complement the current techniques [KNU77, REY81, REM84]. It is believed to simplify the derivations for a wider algorithm class [EIJ92] than the one treated here.
