In the theory of formal languages, the Myhill–Nerode theorem provides a necessary and sufficient condition for a language to be regular. The theorem is named for John Myhill and Anil Nerode, who proved it at the University of Chicago in 1957 (Nerode & Sauer 1957, p. ii).

WebThe Myhill-Nerode Theorem •We know that any equivalence relation partitions its base set into equivalence classes. •The Myhill-Nerode Theorem says that for any language L, there exists a DFA for L with k or fewer states if and only if the L-equivalence relation’s partition has k or fewer classes.
