Weakness Makes Muller Delay Games Hard
share
We show that solving delay games with winning conditions given by deterministic and nondeterministic weak Muller automata is 2EXPTIME-complete respectively 3EXPTIME-complete. Furthermore, doubly and triply exponential lookahead is necessary and sufficient to win such games. These results are the first that show that the succinctness of the automata types used to specify the winning conditions has an influence on the complexity of these problems.
