Description |
Timed automata [1] are a well established theoretical framework used for modeling real time systems. In this paper, we introduce a class of timed automata with updates of the form x :similar to d-y. We show that these updates preserve the decidability of emptiness of classical timed automata with diagonal constraints for similar to is an element of {=, =, not equal}. When used along with additive constraints, these updates give decidable emptiness with 2 or lesser number of clocks, and become undecidable for 3 clocks. This provides a partial solution to a long standing open problem [5].
