What You Must Remember When Processing Data Words

چکیده
We provide a Myhill-Nerode-like theorem that characterizes the class of data languages recognized by deterministic finite-memory automata (DMA). As a byproduct of this characterization result, we obtain a canonical representation for any DMA-recognizable language. We then show that this canonical automaton is minimal in a strong sense: it has the minimal number of control states and also the minimal amount of internal storage.

The same holds true for research studies, for which 1 of the main methods we use to communicate our message is in figures and graphs. Figures and graphs tell much of the story by giving readers a visual anchor to help them see, understand, and rem...
