1 Uppaal Stratego Alexandre David Peter Gjøl Jensen Kim Guldstrand Larsen Marius Mikucionis Jakob Haahr Taankvist Department of Computer Science, Aalborg University, Selma Lagerlöfs Vej 300, 9220 Aalborg Øst, Denmark October 30, 2014

2 Motivation - Different Uppaal versions Uppaal Uppaal-SMC

3 Motivation - Uppaal Stratego Uppaal Uppaal-SMC

4 Branches of Uppaal - Uppaal Classical Uppaal Classical timed model checking Timed Automata (TAs) Safety - A[] not (Peter.SEC1 && Kim.Done Liveness - A<> Peter.Done && Jakob.Done && Kim.Done && Marius.Done True/False answers

5 Branches of Uppaal - Timed Games (TGAs) (Controller/Environment) Find a strategy Safety - A[] Peter.Done && Jakob.Done && Kim.Done && Marius.Done imply time <= 60 Strategies (most permissive)

6 Branches of Uppaal - Uppaal-SMC Stochastic timed automata. Probabilities - Pr[<=100] (<> Peter.Done && Jakob.Done && Kim.Done && Marius.Done && time <= 60) Expectations E[<=100,1000] (max: Peter.WTime) Quantitative answers or True/False answers

7 Branches of Uppaal player games (Controller/stochastic environment) Learn a strategy Maximize/minimize (mine (Peter.WTime) [<=100]: Near optimal <> Peter.Done)

8 Contribution Merge Uppaal,, Uppaal-SMC and Make accessible Facilitate exploration of strategy-space

15 Updated Query Language Strategy generators using Minimize objective strategy DS = mine (expr) [bound]: <> prop under NS Maximize objective strategy DS = maxe (expr) [bound]: <> prop under NS Strategy generators using Guarantee objective strategy NS = control: A<> prop Guarantee objective strategy NS = control: A[] prop Statistical Model Checking Queries Hypothesis testing Pr[bound](<> prop)>=0.1 under SS Evaluation Pr[bound](<> prop) under SS Comparison Pr[bound](<> prop1) under SS1 >= Pr[<=20](<> prop2) under SS2 Expected value E[bound;int](min: prop) under SS Simulations simulate int [bound]{expr1,expr2} under SS Safety Liveness A[] prop under NS A<> prop under NS Model checking queries

16 Demonstration

17 Conclusions and Further Work Conclusions Integration of Uppaal, Uppaal-SMC, and New ways of exploring First time is accessible Further work Include other versions of Uppaal Play against learned Export/import More use of (Model check of learned )
