Abstract

Although the component automata of a cooperating distributed system (CD-system) of stateless deterministic R(1)-automata are all deterministic, the CD-system itself is not. Here we study CDsystems of stateless deterministic R(1)-automata that are themselves completely deterministic. These CD-systems correspond to deterministic finite-state acceptors with translucent letters. We investigate the expressive power of these systems, study the closure properties of the class of languages they accept, and show that the inclusion problem for these systems is undecidable, while their universe problem is decidable.
