Résumé:	Enhanced Distributed Behavioral Cartography of Parametric Timed Automata
Description:	Hoang Gia Nguyen Parametric timed automata (PTA) allow the specification and verification of timed systems incompletely specified, or subject to future changes. The behavioral cartography splits the parameter space of PTA in tiles in which the discrete behavior is uniform. Applications include the optimization of timing constants, and the measure of the system robustness w.r.t. the untimed language. Here, we present enhanced distributed master-worker algorithms to compute the cartography efficiently. Experimental results show that our new algorithms significantly outperform previous distribution techniques.
