To perform veri cation of digital systems with time bounded delays, it is essential to characterize the space of all possible system behaviors. In this paper, we describe our analy...
In this paper, we strengthen two recent undecidability results of [9,10] about weighted timed automata, an extension of timed automata with cost variables. More precisely, we prop...
This paper describes an unsupervised algorithm for segmenting categorical time series. The algorithm first collects statistics about the frequency and boundary entropy of ngrams, t...
We consider the problem of computing concrete diagnostics for timed automata and reachability properties. Concrete means containing information both about the discrete state change...
