31. Within the Chomsky hierarchy, the regular languages , the context-free languages, and the recursively enumerable languages are all full AFLs. 32. The zeta function of a regular language is not in general rational, but that of a cyclic language is. 33. Though still unproven, this type of " unusual " discourse further emphasizes a distinction between complimentary and regular language . 34. In practice, there are many languages that can be described by rules, such as regular languages or context-free languages. 35. Soon, using nondeterministic automata, they were able to re-prove Kleene's result that finite state machines exactly accept regular languages . 36. For example, the set of binary strings with an even number of zeroes is a regular language ( cf. 37. For a regular language , the syntactic monoid is isomorphic to the transformation monoid of the minimal automaton of the language. 38. To the older generations, Bob Hope is a great man who articulated the humor of the regular man in regular language . 39. In this algebraic context, the regular languages ( corresponding to Boolean-weighted rational expressions ) are usually called " rational languages ". 40. Not all regular languages can be induced in this way ( see language identification in the limit ), but many can.
