Minimum-Cost Reachability for Priced Timed Automata
This paper introduces the model of linearly priced timed automata as an extension of timed automata, with prices on both transitions and locations. For this model we consider the minimum-cost reachability problem: i.e. given a linearly priced timed automaton and a target state, determine the minimum cost of executions from the initial state to the target state. This problem generalizes the mini...
متن کاملUndecidability of Cost-Bounded Reachability in Priced Probabilistic Timed Automata
Priced Probabilistic Timed Automata (PPTA) extend timed automata with cost-rates in locations and discrete probabilistic branching. The model is a natural combination of Priced Timed Automata and Probabilistic Timed Automata. In this paper we focus on cost-bounded probabilistic reachability for PPTA, which determines if the maximal probability to reach a goal location within a given cost bound ...
متن کاملRevisiting Decidability and Optimum Reachability for Multi-Priced Timed Automata
We investigate the optimum reachability problem for MultiPriced Timed Automata (MPTA) that admit both positive and negative costs on edges and locations, thus bridging the gap between the results of Bouyer et al. (2007) and of Larsen and Rasmussen (2008). Our contributions are the following: (1) We show that even the location reachability problem is undecidable for MPTA equipped with both posit...
متن کاملComputing Optimal Reachability Costs in Priced Dense-Timed Pushdown Automata
We study priced dense-timed pushdown automata that are a generalization of the classic model of pushdown automata, in the sense that they operate on real-valued clocks, and that the stack symbols have real-valued ages. Furthermore, the model allows a cost function that assigns transition costs to transitions and storage costs to stack symbols. We show that the optimal cost, i.e., the infimum of...
متن کاملAs Cheap as Possible: Efficient Cost-Optimal Reachability for Priced Timed Automata
In this paper we present an algorithm for efficiently computing optimal cost of reaching a goal state in the model of Linearly Priced Timed Automata (LPTA). The central contribution of this paper is a priced extension of so-called zones. This, together with a notion of facets of a zone, allows the entire machinery for symbolic reachability for timed automata in terms of zones to be lifted to co...
