Paper is here. The following incorrect claim is not unusual in the process algebra literature. Basically, what is missing [in classical automata theory] is the notion of interaction: during the execution from initial state to fi nal state, a system may interact with another system. This is needed in order to describe parallel or distributed systems, [...]
The long awaited process algebra paper is now finally available in PDF Reducing Process Algebra.
The first part of a critique of process algebra is below. This relates to the Recursion and State paper and explicatory blog entry where I show how to compose classical automata and define them “abstractly” and to a complaint about the weak critique of automata theory in standard process algebra literature and also to a [...]
