Alternating Timed Automata over Bounded Time
<11>
This paper caps and unifies two long-running, distinct research threads in the real-time verification community, by defining a class of timed languages extending Alur-Dill timed regular languages that are closed under all Boolean operations, and moreover are "fully decidable" (in the sense of Henzinger) over bounded time, i.e., have decidable emptiness and language inclusion problems over finite time intervals. A key ingredient is to establish the decidability of a class of parametric McNaughton games that are played over timed words and that have winning conditions expressed in the monadic logic of order augmented with the distance-one relation.
