Abstract

A restarting transducer is a restarting automaton that is equipped with an output function. Accordingly, restarting transducers compute binary relations, and deterministic restarting transducers compute functions. Here we characterize the rational functions and some of their proper subclasses by certain types of deterministic restarting transducers with window size one.
