Degrees of Lookahead in Context-free Infinite Games

23.pdf (0.5 MB)


We continue the investigation of delay games, infinite games in which one player may postpone her moves for some time to obtain a lookahead on her opponent's moves. We show that the problem of determining the winner of such a game is undecidable for deterministic context-free winning conditions. Furthermore, we show that the necessary lookahead to win a deterministic context-free delay game cannot be bounded by any elementary function. Both results hold already for restricted classes of deterministic context-free winning conditions.
