Revisiting Decidability and Optimum Reachability for Multi-Priced Timed Automata [chapter]

Martin Fränzle, Mani Swaminathan
2009 Lecture Notes in Computer Science  
We investigate the optimum reachability problem for Multi-Priced Timed Automata (MPTA) that admit both positive and negative costs on edges and locations, thus bridging the gap between the results of Bouyer  ...  Under such a condition, the location reachability problem is shown to be decidable and the optimum cost is shown to be computable for MPTA with positive and negative costs and a bounded budget.  ...  We wish to thank Ernst-Rüdiger Olderog and the reviewers for useful comments that helped in improving the presentation of this paper.  ...

Timed Network Games with Clocks [article]

Guy Avni and Shibashis Guha and Orna Kupferman
2018 arXiv   pre-print
Each vertex v in the network is associated with a cost function, mapping the load on v to the price that a player pays for staying in v for one time unit with this load.  ...  In the model we study, the network is equipped with clocks, and, as in timed automata, edges are guarded by constraints on the values of the clocks, and their traversal may involve a reset of some clocks  ...  This work belongs to a line of works that transfer concepts and ideas between the areas of formal verification and algorithmic game theory: logics for specifying multi-agent systems [9, 26] , studies  ...

Optimal-Cost Reachability Analysis Based on Time Petri Nets

Hanifa Boucheneb, Didier Lime, Olivier H. Roux, Charlotte Seidner
2018 2018 18th International Conference on Application of Concurrency to System Design (ACSD)  
This paper shows that for some subclasses of cost time Petri nets, the optimalcost reachability problem can be solved more efficiently using a method based on the state classes, without resorting to linear  ...  This paper investigates the optimal-cost reachability problem in the context of time Petri nets, where a rate cost is associated with each place.  ...  The optimal-cost reachability problem has been addressed for Priced Timed Automata (PTAs for short) in [1] - [5] using the region graphs and the zone based graphs.  ...

Introduction to the Theory of Complexity

V. J. Rayward-Smith
1995 Journal of the Operational Research Society  
The domain of R is the set of all x such that x, y ∈ R for some y; the codomain or range of R is the set of all y such that x, y ∈ R for some x.  ...  Two pairs x, y and z, w are equal if and only if x = z and y = w. The Cartesian product of two sets A and B, denoted as A × B, is the set of all ordered pairs x, y with x ∈ A and y ∈ B.  ...  Silvestri for pointing out many corrections and for suggesting simpler and clearer proofs of some results.  ...

Learning in Auctions: Regret is Hard, Envy is Easy [article]

Constantinos Daskalakis, Vasilis Syrgkanis
2016 arXiv   pre-print
We show that this obstacle is insurmountable: there are no polynomial-time no-regret algorithms for SiSPAs, unless RP⊇ NP, even when the bidders are unit-demand.  ...  Our results for XOS valuations are enabled by a novel Follow-The-Perturbed-Leader algorithm for settings where the number of experts is infinite, and the payoff function of the learner is non-linear.  ...  Revisiting simultaneous second price auctions it is easy to see that the mechanism is 1-value covered and (0, 1)-threshold covered when players actions are restricted to no-overbidding actions and valuations  ...

Towards efficient analysis of Markov automata [article]

Yuliya Butkova, Universität Des Saarlandes
Two of the most challenging problems for Markov automata to date are (i) the optimal time-bounded reachability probability and (ii) the optimal long-run average rewards.  ...  We approach the problem of time-bounded reachability from two different angles.  ...  Analysis of time-bounded properties, such as time-bounded reachability and cumulative time-bounded reward, is by far the most challenging problem for Markov automata.  ...
