Given a language Land a nondeterministic finite automaton M, we consider whether we can determine efficiently (in the size of M) if Maccepts at least one word in L, or infinitely many words. Given that Maccepts at least one word in L, we consider how long the shortest word can be. The languages Lthat we examine include the palindromes, the non-palindromes, the k-powers, the non-k-powers, the powers, the non-powers (also called primitive words), and words matching a general pattern.
