Although statistical and logical methods are different in nature, we show that they can be successfully combined for system analysis. In the first part of the dissertation we present a new statistical algorithm for the verification of probabilistic systems with respect to unbounded properties, including linear temporal logic. Our algorithm often performs faster than the previous approaches, and at the same time requires less information about the system. In addition, our method can be generalized to unbounded quantitative properties such as mean-payoff bounds. In the second part, we introduce two techniques for comparing probabilistic systems. Probabilistic systems are typically compared using the notion of equivalence, which requires the systems to have the equal probability of all behaviors. However, this notion is often too strict, since probabilities are typically only empirically estimated, and any imprecision may break the relation between processes. On the one hand, we propose to replace the Boolean notion of equivalence by a quantitative distance of similarity. For this purpose, we introduce a statistical framework for estimating distances between Markov chains based on their simulation runs, and we investigate which distances can be approximated in our framework. On the other hand, we propose to compare systems with respect to a new qualitative logic, which expresses that behaviors occur with probability one or a positive probability. This qualitative analysis is robust with respect to modeling errors and applicable to many domains. In the last part, we present a new quantifier-free logic for integer arrays, which allows us to express counting. Counting properties are prevalent in array-manipulating programs, however they cannot be expressed in the quantified fragments of the theory of arrays. We present a decision procedure for our logic, and provide several complexity results."}],"file_date_updated":"2020-07-14T12:44:34Z","publication_identifier":{"issn":["2663-337X"]},"publication_status":"published","supervisor":[{"first_name":"Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"}],"month":"01","department":[{"_id":"ToHe"}],"file":[{"content_type":"application/pdf","access_level":"open_access","file_name":"IST-2017-730-v1+1_Statistical_and_Logical_Methods_for_Property_Checking.pdf","checksum":"1406a681cb737508234fde34766be2c2","relation":"main_file","creator":"system","date_updated":"2020-07-14T12:44:34Z","date_created":"2018-12-12T10:11:26Z","file_size":1028586,"file_id":"4880"}],"oa":1,"language":[{"iso":"eng"}],"pubrep_id":"730","citation":{"apa":"Daca, P.

Long-run average rewards provide a mathematically elegant formalism for expressing long term performance. Value iteration (VI) is one of the simplest and most efficient algorithmic approaches to MDPs with other properties, such as reachability objectives. Unfortunately, a naive extension of VI does not work for MDPs with long-run average rewards, as there is no known stopping criterion. In this work our contributions are threefold. (1) We refute a conjecture related to stopping criteria for MDPs with long-run average rewards. (2) We present two practical algorithms for MDPs with long-run average rewards based on VI. First, we show that a combination of applying VI locally for each maximal end-component (MEC) and VI for reachability objectives can provide approximation guarantees. Second, extending the above approach with a simulation-guided on-demand variant of VI, we present an anytime algorithm that is able to deal with very large models. (3) Finally, we present experimental results showing that our methods significantly outperform the standard approaches on several benchmarks."}],"intvolume":"     10426","date_created":"2018-12-11T11:47:41Z","volume":10426,"title":"Value iteration for long run average reward in markov decision processes","oa_version":"Submitted Version","scopus_import":1,"day":"13","author":[{"first_name":"Pranav","last_name":"Ashok","full_name":"Ashok, Pranav"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","orcid":"0000-0002-4561-241X"},{"first_name":"Przemyslaw","id":"49351290-F248-11E8-B48F-1D18A9856A87","full_name":"Daca, Przemyslaw","last_name":"Daca"},{"last_name":"Kretinsky","id":"44CEF464-F248-11E8-B48F-1D18A9856A87","full_name":"Kretinsky, Jan","first_name":"Jan","orcid":"0000-0002-8122-2881"},{"full_name":"Meggendorfer, Tobias","last_name":"Meggendorfer","first_name":"Tobias"}]},{"ddc":["004"],"quality_controlled":"1","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","doi":"10.4230/LIPIcs.CONCUR.2016.20","alternative_title":["LIPIcs"],"type":"conference","date_updated":"2023-09-07T11:58:33Z","_id":"1093","project":[{"grant_number":"267989","name":"Quantitative Reactive Modeling","call_identifier":"FP7","_id":"25EE3708-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"The Wittgenstein Prize","grant_number":"Z211","call_identifier":"FWF"}],"status":"public","conference":{"end_date":"2016-08-26","start_date":"2016-08-23","name":"CONCUR: Concurrency Theory","location":"Quebec City; Canada"},"date_published":"2016-08-01T00:00:00Z","acknowledgement":"This research was funded in part by the European Research Council (ERC) under grant agreement 267989\r\n(QUAREM), the Austrian Science Fund (FWF) under grants project S11402-N23 (RiSE and SHiNE)\r\nand Z211-N23 (Wittgenstein Award), by the Czech Science Foundation Grant No. P202/12/G061, and\r\nby the SNSF Advanced Postdoc.

Using reduction to counter machines, we show that the satisfiability problem of AFL is PSPACE-complete, and with a natural restriction the complexity decreases to NP. We also show that adding either universal quantifiers or concatenation leads to undecidability.\r\nAFL contains terms that fold a function over an array. We demonstrate that folding, a well-known concept from functional languages, allows us to concisely summarize loops that count over arrays, which occurs frequently in real-life programs. We provide a tool that can discharge proof obligations in AFL, and we demonstrate on practical examples that our decision procedure can solve a broad range of problems in symbolic testing and program verification."}],"publication_status":"published","month":"07","department":[{"_id":"ToHe"}],"language":[{"iso":"eng"}],"oa":1,"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Daca, P., Henzinger, T.

However, it suffers from the path-explosion problem and often fails to find tests that cover difficult-to-reach parts of programs. In contrast, model checkers based on counterexample-guided abstraction refinement explore programs exhaustively, while failing to scale on large programs with precision. In this paper, we present a novel method that iteratively combines concolic testing and model checking to find a test suite for a given coverage criterion. If concolic testing fails to cover some test goals, then the model checker refines its program abstraction to prove more paths infeasible, which reduces the search space for concolic testing. We have implemented our method on top of the concolictesting tool Crest and the model checker CpaChecker. We evaluated our tool on a collection of programs and a category of SvComp benchmarks. In our experiments, we observed an improvement in branch coverage compared to Crest from 48% to 63% in the best case, and from 66% to 71% on average.","lang":"eng"}],"intvolume":"      9583","publication_status":"published","month":"01","department":[{"_id":"ToHe"}],"oa":1,"language":[{"iso":"eng"}],"citation":{"ama":"Daca P, Gupta A, Henzinger TA.

In comparison to previous algorithms for statistical model checking our method is not only faster in many cases but also requires less information about the system, namely, only the minimum transition probability that occurs in the Markov chain.

We focus on qualitative properties for MDPs that can express that desired behaviors of the system arise almost-surely (with probability 1) or with positive probability. We introduce a new simulation relation to capture the refinement relation of MDPs with respect to qualitative properties, and present discrete graph algorithms with quadratic complexity to compute the simulation relation. We present an automated technique for assume-guarantee style reasoning for compositional analysis of two-player games by giving a counterexample guided abstraction-refinement approach to compute our new simulation relation. We show a tight link between two-player games and MDPs, and as a consequence the results for games are lifted to MDPs with qualitative properties. We have implemented our algorithms and show that the compositional analysis leads to significant improvements.

While we focus on asynchronous models and the IOCO conformance relation, the resulting methodology can be applied to a broader class of systems.","lang":"eng"}],"file_date_updated":"2020-07-14T12:46:46Z","publication_identifier":{"issn":["2664-1690"]},"publication_status":"published"},{"publication_identifier":{"issn":["2664-1690"]},"publication_status":"published","file_date_updated":"2020-07-14T12:46:47Z","page":"31","has_accepted_license":"1","abstract":[{"lang":"eng","text":"We consider Markov decision processes (MDPs) which are a standard model for probabilistic systems.
