[컴퓨테이션이론] ch1. Convert NFA to DFA (2)

Regular language <-> DFA & NFA

A language is regular <=> if some nondeterministic finite automaton recognizes it

-> : Because a regular language has a DFA recognizing it and any DFA is also an NFA

<- : If an NFA recognizes some language, so does some DFA, and hence the language is regular
