Bounded-Rate Multi-Mode Systems Based Motion Planning
Devendra Bhave, Sagar Jha, Shankara Narayanan Krishna +2
Bounded-rate multi-mode systems are hybrid systems that can switch among a finite set of modes. Its dynamics is specified by a finite number of real-valued variables with mode-depe…
Improved Undecidability Results for Reachability Games on Recursive Timed Automata
Shankara Narayanan Krishna, Lakshmi Manasa, Ashutosh Trivedi
We study reachability games on recursive timed automata (RTA) that generalize Alur-Dill timed automata with recursive procedure invocation mechanism similar to recursive state mach…
First-order definable string transformations
Emmanuel Filiot, Shankara Narayanan Krishna, Ashutosh Trivedi
The connection between languages defined by computational models and logic for languages is well-studied. Monadic second-order logic and finite automata are shown to closely corres…
On The Reachability Problem for Recursive Hybrid Automata with One and Two Players
Shankara Narayanan Krishna, Lakshmi Manasa, Ashutosh Trivedi
Motivated by the success of bounded model checking framework for finite state machines, Ouaknine and Worrell proposed a time-bounded theory of real-time verification by claiming th…
Adding Negative Prices to Priced Timed Games
Thomas Brihaye, Gilles Geeraerts, Shankara Narayanan Krishna +3
Priced timed games (PTGs) are two-player zero-sum games played on the infinite graph of configurations of priced timed automata where two players take turns to choose transitions i…
