Clocks and zones timed automata
WebNov 5, 2003 · The key step to guarantee termination of reachability analysis for timed automata is the normalisation algorithms for clock constraints i.e. zones represented as DBM’s (Difference Bound Matrices). In automata theory, a timed automaton is a finite automaton extended with a finite set of real-valued clocks. During a run of a timed automaton, clock values increase all with the same speed. Along the transitions of the automaton, clock values can be compared to integers. These comparisons form guards that may … See more Before formally defining what a timed automaton is, some examples are given. Consider the language $${\displaystyle {\mathcal {L}}}$$ of timed-words $${\displaystyle w}$$ over the unary alphabet See more The class of languages recognized by non-deterministic timed automata is: • closed under union, indeed, the disjoint union of two timed automata recognize the union of the language recognized by those automata. • closed under intersection.
