On the Power of Finite Ambiguity in Büchi Complementation
Weizhi Feng, Yong Li, Andrea Turrini +2
In this work, we exploit the power of \emph{finite ambiguity} for the complementation problem of Büchi automata by using reduced run directed acyclic graphs (DAGs) over infinite wo…

Congruence Relations for Büchi Automata
Yong Li, Yih-Kuen Tsay, Andrea Turrini +2
We revisit here congruence relations for Büchi automata, which play a central role in the automata-based verification. The size of the classical congruence relation is in $3^{\math…
