Abstract
For each two-way alternating finite automaton (afa) A with s states, we directly build a afa\(A^c \) with \(O(s^6)\) states which accepts exactly those inputs that are not accepted by A. This improves upon the previously best-known construction, which was both more expensive and more complicated, as it required \(O(s^7)\) states and involved building and simulating an intermediate linear-bounded automaton.
