From bidirectionality to alternation

By Nir Piterman and M.Y. Vardi


We describe an explicit simulation of 2-way nondeterministic automata by 1-way alternating\ud automata with quadratic blow-up. We first describe the construction for automata on finite words,\ud and extend it to automata on infinite words.Peer-reviewedPost-prin
