Complexity Bounds for the Verification of Real-Time Software
We present uniform approaches to establish complexity bounds for decision problems such as reachability and simulation, that arise naturally in the verification of timed software s...

On Extremal Cases of Hopcroft's Algorithm
In this paper we consider the problem of minimization of deterministic finite automata (DFA) with reference to Hopcroft’s algorithm. Hopcroft’s algorithm has several degrees o...

Revisiting Digitization, Robustness, and Decidability for Timed Automata
We consider several questions related to the use of digitization techniques for timed automata. These very successful techniques reduce dense-time language inclusion problems to d...

Decidability and Complexity Results for Timed Automata via Channel Machines
Abstract. This paper is concerned with the language inclusion problem for timed automata: given timed automata A and B, is every word accepted by B also accepted by A? Alur and Dil...

On the use of learning automata in the control of broadcast networks: a methodology
Due to its fixed assignment nature, the well-known time division multiple access (TDMA) protocol suffers from poor performance when the offered traffic is bursty. In this paper, an...
