Abstract

Data Flow Analysis as expressed by Monotone Frameworks is often associated with classical imperative programming languages and has played a crucial role in the efficient implementation of these languages. Robin Milner's Calculus of Communicating Systems, CCS, is concerned with modelling concurrent systems and has mainly been analysed using types and control flow analyses. In the present paper we present an instance of a Monotone Framework together with a novel worklist algorithm for more precisely approximating the flow-sensitive control structure of even infinitary processes expressed in CCS.
