WebThese languages are exactly all languages that can be decided by a finite state automaton. Additionally, this family of formal languages can be obtained by regular expressions . … WebLet us call Wheeler languages this class. First of all, Wheeler languages are clearly regular since, by definition, they are accepted by finite state automata. Moreover, all finite languages are Wheeler because they can be recognized by a tree-shaped automaton, which (as seen in Section 3.5) is always prefix-sortable.

Webautomata is underlined, together with recent results on deterministic pushdown automata. As in the case of nite automata, the link with group theory is mentioned, including an important result on context-free groups. The last stage of the hierarchy, the class of recursivelyenumerable languages is introduced through Turing machines.
