In real life, hardware and software systems are rarely constructed from scratch. Rather, a system is typically constructed from a library of components. Lustig and Vardi formalized this intuition and studied LTL synthesis from component libraries. In real life, designers seek optimal systems. In this paper we add optimality considerations to the setting. We distinguish between quality considerations (for example, size - the smaller a system is, the better it is), and pricing (for example, the payment to the company who manufactured the component). We study the problem of designing systems with minimal quality-cost and price. A key point is that while the quality cost is individual - the choices of a designer are independent of choices made by other designers that use the same library, pricing gives rise to a resource-allocation game - designers that use the same component share its price, with the share being proportional to the number of uses (a component can be used several times in a design). We study both closed and open settings, and in both we solve the problem of finding an optimal design. In a setting with multiple designers, we also study the game-theoretic problems of the induced resource-allocation game.","lang":"eng"}]},{"quality_controlled":"1","page":"143 - 166","date_updated":"2023-09-20T12:07:48Z","_id":"1066","type":"journal_article","doi":"10.1016/j.ic.2016.10.006","article_processing_charge":"No","publisher":"Elsevier","ec_funded":1,"date_published":"2017-06-01T00:00:00Z","project":[{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307","call_identifier":"FP7"},{"_id":"25EE3708-B435-11E9-9278-68D0E5697425","name":"Quantitative Reactive Modeling","grant_number":"267989","call_identifier":"FP7"},{"call_identifier":"FWF","grant_number":"P 23499-N23","name":"Modern Graph Algorithmic Techniques in Formal Verification","_id":"2584A770-B435-11E9-9278-68D0E5697425"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"status":"public","publication":"Information and Computation","publist_id":"6322","year":"2017","isi":1,"external_id":{"isi":["000402025600002"]},"related_material":{"record":[{"id":"5428","relation":"earlier_version","status":"public"}]},"publication_status":"published","abstract":[{"lang":"eng","text":"Simulation is an attractive alternative to language inclusion for automata as it is an under-approximation of language inclusion, but usually has much lower complexity.

While fair trace inclusion is PSPACE-complete, fair simulation can be computed in polynomial time. For weighted automata, the (quantitative) language inclusion problem is undecidable in general, whereas the (quantitative) simulation reduces to quantitative games, which admit pseudo-polynomial time algorithms.\r\n\r\nIn this work, we study (quantitative) simulation for weighted automata with Büchi acceptance conditions, i.e., we generalize fair simulation from non-weighted automata to weighted automata.

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_status":"published","publication_identifier":{"issn":["2663-337X"]},"supervisor":[{"full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","orcid":"0000−0002−2985−7724","first_name":"Thomas A"}],"month":"01","department":[{"_id":"ToHe"}],"file":[{"file_size":1028586,"date_created":"2018-12-12T10:11:26Z","creator":"system","date_updated":"2020-07-14T12:44:34Z","file_id":"4880","file_name":"IST-2017-730-v1+1_Statistical_and_Logical_Methods_for_Property_Checking.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"1406a681cb737508234fde34766be2c2"}],"oa":1,"pubrep_id":"730","language":[{"iso":"eng"}],"citation":{"ama":"Daca P.

In this work, we present a complete picture of decidability and complexity for the following problems: (1) deciding whether, for a given threshold k , the edit distance from a pushdown automaton to a finite automaton is at most k , and (2) deciding whether the edit distance from a pushdown automaton to a finite automaton is finite.

The main idea is that we monitor each simulation run on the fly, in order to detect quickly if a bottom strongly connected component is entered with high probability, in which case the simulation run can be terminated early. As a result, our simulation runs are often much shorter than required by termination bounds that are computed a priori for a desired level of confidence on a large state space. 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. In addition, our method can be generalised to unbounded quantitative properties such as mean-payoff bounds.

The approach allows programmers to program assuming a friendly, non-preemptive scheduler, and our synthesis procedure inserts synchronization to ensure that the final program works even with a preemptive scheduler. The correctness specification is implicit, inferred from the non-preemptive behavior. Let us consider sequences of calls that the program makes to an external interface. The specification requires that any such sequence produced under a preemptive scheduler should be included in the set of sequences produced under a non-preemptive scheduler. We guarantee that our synthesis does not introduce deadlocks and that the synchronization inserted is optimal w.r.t. a given objective function. The solution is based on a finitary abstraction, an algorithm for bounded language inclusion modulo an independence relation, and generation of a set of global constraints over synchronization placements. Each model of the global constraints set corresponds to a correctness-ensuring synchronization placement. The placement that is optimal w.r.t. the given objective function is chosen as the synchronization solution. We apply the approach to device-driver programming, where the driver threads call the software interface of the device and the API provided by the operating system. Our experiments demonstrate that our synthesis method is precise and efficient. The implicit specification helped us find one concurrency bug previously missed when model-checking using an explicit, user-provided specification. We implemented objective functions for coarse-grained and fine-grained locking and observed that different synchronization placements are produced for our experiments, favoring a minimal number of synchronization operations or maximum concurrency, respectively.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by/4.0/","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"        50","publication_status":"published","file_date_updated":"2020-07-14T12:44:44Z","author":[{"last_name":"Cerny","id":"4DCBEFFE-F248-11E8-B48F-1D18A9856A87","full_name":"Cerny, Pavol","first_name":"Pavol"},{"first_name":"Edmund","last_name":"Clarke","full_name":"Clarke, Edmund"},{"orcid":"0000−0002−2985−7724","first_name":"Thomas A","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger"},{"last_name":"Radhakrishna","id":"3B51CAC4-F248-11E8-B48F-1D18A9856A87","full_name":"Radhakrishna, Arjun","first_name":"Arjun"},{"last_name":"Ryzhyk","full_name":"Ryzhyk, Leonid","first_name":"Leonid"},{"last_name":"Samanta","id":"3D2AAC08-F248-11E8-B48F-1D18A9856A87","full_name":"Samanta, Roopsha","first_name":"Roopsha"},{"id":"3D6E8F2C-F248-11E8-B48F-1D18A9856A87","full_name":"Tarrach, Thorsten","last_name":"Tarrach","first_name":"Thorsten","orcid":"0000-0003-4409-8487"}],"day":"01","scopus_import":"1","oa_version":"Published Version","title":"From non-preemptive to preemptive scheduling using synchronization synthesis","volume":50,"date_created":"2018-12-11T11:51:27Z","project":[{"_id":"25EE3708-B435-11E9-9278-68D0E5697425","name":"Quantitative Reactive Modeling","grant_number":"267989","call_identifier":"FP7"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering","grant_number":"S 11407_N23","call_identifier":"FWF"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211","name":"The Wittgenstein Prize","call_identifier":"FWF"},{"_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854","name":"IST Austria Open Access Fund"}],"publication":"Formal Methods in System Design","status":"public","ec_funded":1,"date_published":"2017-06-01T00:00:00Z","isi":1,"year":"2017","external_id":{"isi":["000399888900001"]},"related_material":{"record":[{"id":"1729","relation":"earlier_version","status":"public"}]},"publist_id":"5929","page":"97 -

In the model, weight parameters represent the gene interaction strength that may change due to genetic mutations. For a property of interest, we synthesise the constraints over the parameter space that represent the set of GRNs satisfying the property. We experimentally show that our parameter synthesis procedure computes the mutational robustness of GRNs—an important problem of interest in evolutionary biology—more efficiently than the classical simulation method.

We propose a solution based on iterative abstraction-refinement, and turn-based 2-player probabilistic games. While the theoretical guarantee of our algorithm after any finite number of iterations is only a partial solution, we show that if our algorithm terminates, then the result is the set of all satisfying initial states. Moreover, for any (partial) solution our algorithm synthesizes witness control strategies to ensure almost-sure satisfaction of the temporal logic specification. While the proposed algorithm guarantees progress and soundness in every iteration, it is computationally demanding.

The model-measuring problem presupposes a distance function on models. We concentrate on . automatic distance functions, which are defined by weighted automata. The model-measuring problem subsumes several generalizations of the classical model-checking problem, in particular, quantitative model-checking problems that measure the degree of satisfaction of a specification; robustness problems that measure how much a model can be perturbed without violating the specification; and parameter synthesis for hybrid systems. We show that for automatic distance functions, and (a) . ω-regular linear-time, (b) . ω-regular branching-time, and (c) hybrid specifications, the model-measuring problem can be solved.We use automata-theoretic model-checking methods for model measuring, replacing the emptiness question for word, tree, and hybrid automata by the . optimal-value question for the weighted versions of these automata. For automata over words and trees, we consider weighted automata that accumulate weights by maximizing, summing, discounting, and limit averaging. For hybrid automata, we consider monotonic (parametric) hybrid automata, a hybrid counterpart of (discrete) weighted automata.We give several examples of using the model-measuring problem to compute various notions of robustness and quantitative satisfaction for temporal specifications. Further, we propose the modeling framework for model measuring to ease the specification and reduce the likelihood of errors in modeling.Finally, we present a variant of the model-measuring problem, called the . model-repair problem.

Linearizability is the most popular consistency condition due to its simplicity and general applicability. Nevertheless, for applications that do not require all guarantees offered by linearizability, recent research has focused on improving performance and scalability of concurrent data structures by relaxing their semantics. In this paper, we present local linearizability, a relaxed consistency condition that is applicable to container-type concurrent data structures like pools, queues, and stacks. While linearizability requires that the effect of each operation is observed by all threads at the same time, local linearizability only requires that for each thread T, the effects of its local insertion operations and the effects of those removal operations that remove values inserted by T are observed by all threads at the same time. We investigate theoretical and practical properties of local linearizability and its relationship to many existing consistency conditions. We present a generic implementation method for locally linearizable data structures that uses existing linearizable data structures as building blocks. Our implementations show performance and scalability improvements over the original building blocks and outperform the fastest existing container-type implementations.

The first uses the parallel, breadth-first-search algorithm (PBFS) of the SPIN model checker, when traversing the discrete modes of the HA, and enhances it with a parallel exploration of the continuous states within each mode. We show that this simple-minded extension of PBFS does not provide the desired load balancing in many HA benchmarks. The second algorithm is a task-parallel BFS algorithm (TP-BFS), which uses a cheap precomputation of the cost associated with the post operations (both continuous and discrete) in order to improve load balancing. We illustrate the TP-BFS and the cost precomputation of the post operators on a support-function-based algorithm for state-space exploration. The performance comparison of the two algorithms shows that, in general, TP-BFS provides a better utilization/load-balancing of the CPU. Both algorithms are implemented in the model checker XSpeed. Our experiments show a maximum speed-up of more than 2000 χ on a navigation benchmark, with respect to SpaceEx LGG scenario. In order to make the comparison fair, we employed an equal number of post operations in both tools. To the best of our knowledge, this paper represents the first attempt to provide parallel, reachability-analysis algorithms for HA.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1606.05473"}],"publication_status":"published","quality_controlled":"1","scopus_import":1,"day":"27","author":[{"full_name":"Gurung, Amit","last_name":"Gurung","first_name":"Amit"},{"first_name":"Arup","full_name":"Deka, Arup","last_name":"Deka"},{"full_name":"Bartocci, Ezio","last_name":"Bartocci","first_name":"Ezio"},{"full_name":"Bogomolov, Sergiy","id":"369D9A44-F248-11E8-B48F-1D18A9856A87","last_name":"Bogomolov","first_name":"Sergiy","orcid":"0000-0002-0686-0365"},{"first_name":"Radu","full_name":"Grosu, Radu","last_name":"Grosu"},{"full_name":"Ray, Rajarshi","last_name":"Ray","first_name":"Rajarshi"}],"doi":"10.1109/MEMCOD.2016.7797741","publisher":"IEEE","title":"Parallel reachability analysis for hybrid systems","oa_version":"Preprint","_id":"1103","date_updated":"2021-01-12T06:48:18Z","date_created":"2018-12-11T11:50:09Z","type":"conference","oa":1,"status":"public","language":[{"iso":"eng"}],"project":[{"_id":"25EE3708-B435-11E9-9278-68D0E5697425","name":"Quantitative Reactive Modeling","grant_number":"267989","call_identifier":"FP7"},{"grant_number":"Z211","name":"The Wittgenstein Prize","call_identifier":"FWF","_id":"25F42A32-B435-11E9-9278-68D0E5697425"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","call_identifier":"FWF"}],"ec_funded":1,"citation":{"ista":"Gurung A, Deka A, Bartocci E, Bogomolov S, Grosu R, Ray R. 2016.

Our approach helps the programmer by automatically fixing concurrency-related bugs, i.e. bugs that occur when the program is executed using an aggressive preemptive scheduler, but not when using a non-preemptive (cooperative) scheduler. Bugs are program behaviours that are incorrect w.r.t. a specification. We consider both user-provided explicit specifications in the form of assertion\r\nstatements in the code as well as an implicit specification. The implicit specification is inferred from the non-preemptive behaviour. Let us consider sequences of calls that the program makes to an external interface. The implicit specification requires that any such sequence produced under a preemptive scheduler should be included in the set of sequences produced under a non-preemptive scheduler. We consider several semantics-preserving fixes that go beyond atomic sections typically explored in the synchronisation synthesis literature. Our synthesis is able to place locks, barriers and wait-signal statements and last, but not least reorder independent statements. The latter may be useful if a thread is released to early, e.g., before some initialisation is completed. We guarantee that our synthesis does not introduce deadlocks and that the synchronisation inserted is optimal w.r.t. a given objective function. We dub our solution trace-based synchronisation synthesis and it is loosely based on counterexample-guided inductive synthesis (CEGIS). The synthesis works by discovering a trace that is incorrect w.r.t. the specification and identifying ordering constraints crucial to trigger the specification violation. Synchronisation may be placed immediately (greedy approach) or delayed until all incorrect traces are found (non-greedy approach). For the non-greedy approach we construct a set of global constraints over synchronisation placements. Each model of the global constraints set corresponds to a correctness-ensuring synchronisation placement. The placement that is optimal w.r.t. the given objective function is chosen as the synchronisation solution. We evaluate our approach on a number of realistic (albeit simplified) Linux device-driver\r\nbenchmarks. The benchmarks are versions of the drivers with known concurrency-related bugs. For the experiments with an explicit specification we added assertions that would detect the bugs in the experiments. Device drivers lend themselves to implicit specification, where the device and the operating system are the external interfaces. Our experiments demonstrate that our synthesis method is precise and efficient. We implemented objective functions for coarse-grained and fine-grained locking and observed that different synchronisation placements are produced for our experiments, favouring e.g. a minimal number of synchronisation operations or maximum concurrency."}],"has_accepted_license":"1","file_date_updated":"2021-11-17T13:46:55Z","publication_identifier":{"issn":["2663-337X"]},"publication_status":"published","oa_version":"Published Version","title":"Automatic synthesis of synchronisation primitives for concurrent programs","day":"07","author":[{"full_name":"Tarrach, Thorsten","id":"3D6E8F2C-F248-11E8-B48F-1D18A9856A87","last_name":"Tarrach","orcid":"0000-0003-4409-8487","first_name":"Thorsten"}],"date_created":"2018-12-11T11:50:19Z","status":"public","project":[{"call_identifier":"FP7","name":"Quantitative Reactive Modeling","grant_number":"267989","_id":"25EE3708-B435-11E9-9278-68D0E5697425"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Rigorous Systems Engineering","grant_number":"S 11407_N23"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"Z211","name":"The Wittgenstein Prize"}],"degree_awarded":"PhD","date_published":"2016-07-07T00:00:00Z","ec_funded":1,"related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"1729"},{"status":"public","relation":"part_of_dissertation","id":"2218"},{"relation":"part_of_dissertation","status":"public","id":"2445"}]},"year":"2016","publist_id":"6230","ddc":["000"],"page":"151","main_file_link":[{"url":"http://thorstent.github.io/theses/phd_thorsten_tarrach.pdf","open_access":"1"}],"publisher":"Institute of Science and Technology Austria","article_processing_charge":"No","alternative_title":["ISTA Thesis"],"doi":"10.15479/at:ista:1130","type":"dissertation","_id":"1130","date_updated":"2023-09-07T11:57:01Z"},{"department":[{"_id":"ToHe"}],"file":[{"date_updated":"2018-12-12T10:09:31Z","creator":"system","file_size":279240,"date_created":"2018-12-12T10:09:31Z","file_id":"4755","access_level":"open_access","content_type":"application/pdf","file_name":"IST-2016-644-v1+1_emsoft-no-format.pdf","relation":"main_file"}],"article_number":"26","month":"10","citation":{"mla":"Avni, Guy, et al. “Synthesizing Time Triggered Schedules for Switched Networks with Faulty Links.” <i>Proceedings of the 13th International Conference on Embedded Software </i>, 26, ACM, 2016, doi:<a href=\"https://doi.org/10.1145/2968478.2968499\">10.1145/2968478.2968499</a>.","apa":"Avni, G., Guha, S., &#38; Rodríguez Navas, G.

These networks rely on the notion of globally discretized time (i.e. time slots) and a static TT schedule that prescribes which message is sent through which link at every time slot, such that all messages reach their destination before a global timeout. These schedules are generated offline, assuming a static network with fault-free links, and entrusting all error-handling functions to the end user. Assuming the network is static is an over-optimistic view, and indeed links tend to fail in practice. We study synthesis of TT schedules on a network in which links fail over time and we assume the switches run a very simple error-recovery protocol once they detect a crashed link. We address the problem of finding a pk; qresistant schedule; namely, one that, assuming the switches run a fixed error-recovery protocol, guarantees that the number of messages that arrive at their destination by the timeout is at least no matter what sequence of at most k links fail. Thus, we maintain the simplicity of the switches while giving a guarantee on the number of messages that meet the timeout. We show how a pk; q-resistant schedule can be obtained using a CEGAR-like approach: find a schedule, decide whether it is pk; q-resistant, and if it is not, use the witnessing fault sequence to generate a constraint that is added to the program. The newly added constraint disallows the schedule to be regenerated in a future iteration while also eliminating several other schedules that are not pk; q-resistant. We illustrate the applicability of our approach using an SMT-based implementation. © 2016 ACM.","lang":"eng"}],"publist_id":"6223","year":"2016","ec_funded":1,"date_published":"2016-10-01T00:00:00Z","conference":{"location":"Pittsburgh, PA, USA","start_date":"2016-10-01","end_date":"2016-10-07","name":"EMSOFT: Embedded Software "},"status":"public","publication":"Proceedings of the 13th International Conference on Embedded Software ","project":[{"call_identifier":"FP7","grant_number":"267989","name":"Quantitative Reactive Modeling","_id":"25EE3708-B435-11E9-9278-68D0E5697425"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","name":"Rigorous Systems Engineering","grant_number":"S 11407_N23","call_identifier":"FWF"},{"name":"The Wittgenstein Prize","grant_number":"Z211","call_identifier":"FWF","_id":"25F42A32-B435-11E9-9278-68D0E5697425"}],"_id":"1135","date_updated":"2021-01-12T06:48:33Z","type":"conference","doi":"10.1145/2968478.2968499","publisher":"ACM","quality_controlled":"1","ddc":["000"]},{"abstract":[{"lang":"eng","text":"Automata with monitor counters, where the transitions do not depend on counter values, and nested weighted automata are two expressive automata-theoretic frameworks for quantitative properties.

We present a complete picture of decidability for such automata, and even an almost-complete picture of computational complexity, for the probabilistic questions we consider. © 2016 ACM."}],"publication_status":"published","author":[{"orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A"},{"last_name":"Otop","id":"2FC5DA74-F248-11E8-B48F-1D18A9856A87","full_name":"Otop, Jan","first_name":"Jan"}],"scopus_import":1,"day":"05","title":"Quantitative automata under probabilistic semantics","oa_version":"Preprint","date_created":"2018-12-11T11:50:21Z","oa":1,"language":[{"iso":"eng"}],"citation":{"ieee":"K.

When such models are employed to answer questions in applications, in order to ensure that the model provides a sufficiently accurate representation of the real system, it is of vital importance that the model parameters are inferred from real measured data. This, however, is often a formidable task and all of the existing methods fail in one case or the other, usually because the underlying CTMC model is high-dimensional and computationally difficult to analyze. The parameter inference methods that tend to scale best in the dimension of the CTMC are based on so-called moment closure approximations. However, there exists a large number of different moment closure approximations and it is typically hard to say a priori which of the approximations is the most suitable for the inference procedure. Here, we propose a moment-based parameter inference method that automatically chooses the most appropriate moment closure method. Accordingly, contrary to existing methods, the user is not required to be experienced in moment closure techniques. In addition to that, our method adaptively changes the approximation during the parameter inference to ensure that always the best approximation is used, even in cases where different approximations are best in different regions of the parameter space. © 2016 Elsevier Ireland Ltd","lang":"eng"}],"date_created":"2018-12-11T11:50:24Z","volume":149,"title":"Adaptive moment closure for parameter inference of biochemical reaction networks","oa_version":"None","scopus_import":1,"day":"01","author":[{"first_name":"Christian","last_name":"Schilling","full_name":"Schilling, Christian"},{"full_name":"Bogomolov, Sergiy","id":"369D9A44-F248-11E8-B48F-1D18A9856A87","last_name":"Bogomolov","orcid":"0000-0002-0686-0365","first_name":"Sergiy"},{"orcid":"0000−0002−2985−7724","first_name":"Thomas A","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger"},{"first_name":"Andreas","full_name":"Podelski, Andreas","last_name":"Podelski"},{"first_name":"Jakob","orcid":"0000-0003-1615-3282","last_name":"Ruess","id":"4A245D00-F248-11E8-B48F-1D18A9856A87","full_name":"Ruess, Jakob"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Schilling, C., Bogomolov, S., Henzinger, T.

A verification tool like SpaceEx is based on the exploration of a symbolic search space (the region space). As a verification tool, it is typically optimized towards proving the absence of errors. In some settings, e.g., when the verification tool is employed in a feedback-directed design cycle, one would like to have the option to call a version that is optimized towards finding an error trajectory in the region space. A recent approach in this direction is based on guided search. Guided search relies on a cost function that indicates which states are promising to be explored, and preferably explores more promising states first. In this paper, we propose an abstraction-based cost function based on coarse-grained space abstractions for guiding the reachability analysis. For this purpose, a suitable abstraction technique that exploits the flexible granularity of modern reachability analysis algorithms is introduced. The new cost function is an effective extension of pattern database approaches that have been successfully applied in other areas. The approach has been implemented in the SpaceEx model checker. The evaluation shows its practical potential."}],"has_accepted_license":"1","file_date_updated":"2020-07-14T12:45:13Z","publication_status":"published","oa_version":"Published Version","title":"Guided search for hybrid systems based on coarse-grained space abstractions","scopus_import":1,"day":"01","author":[{"full_name":"Bogomolov, Sergiy","id":"369D9A44-F248-11E8-B48F-1D18A9856A87","last_name":"Bogomolov","orcid":"0000-0002-0686-0365","first_name":"Sergiy"},{"first_name":"Alexandre","last_name":"Donzé","full_name":"Donzé, Alexandre"},{"first_name":"Goran","last_name":"Frehse","full_name":"Frehse, Goran"},{"full_name":"Grosu, Radu","last_name":"Grosu","first_name":"Radu"},{"full_name":"Johnson, Taylor","last_name":"Johnson","first_name":"Taylor"},{"first_name":"Hamed","last_name":"Ladan","full_name":"Ladan, Hamed"},{"last_name":"Podelski","full_name":"Podelski, Andreas","first_name":"Andreas"},{"full_name":"Wehrle, Martin","last_name":"Wehrle","first_name":"Martin"}],"date_created":"2018-12-11T11:53:34Z","volume":18,"publication":"International Journal on Software Tools for Technology Transfer","status":"public","project":[{"name":"Quantitative Reactive Modeling","grant_number":"267989","call_identifier":"FP7","_id":"25EE3708-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","name":"The Wittgenstein Prize","grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Rigorous Systems Engineering","grant_number":"S 11407_N23"}],"date_published":"2016-08-01T00:00:00Z","ec_funded":1,"year":"2016","publist_id":"5431","ddc":["000"],"page":"449 - 467","quality_controlled":"1","publisher":"Springer","article_processing_charge":"Yes (via OA deal)","doi":"10.1007/s10009-015-0393-y","type":"journal_article","_id":"1705","date_updated":"2021-01-12T06:52:38Z"},{"oa_version":"Preprint","title":"PSYNC: A partially synchronous language for fault-tolerant distributed algorithms","author":[{"id":"2B2B5ED0-F248-11E8-B48F-1D18A9856A87","full_name":"Dragoi, Cezara","last_name":"Dragoi","first_name":"Cezara"},{"first_name":"Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A"},{"last_name":"Zufferey","id":"4397AC76-F248-11E8-B48F-1D18A9856A87","full_name":"Zufferey, Damien","first_name":"Damien","orcid":"0000-0002-3197-8736"}],"scopus_import":1,"day":"11","date_created":"2018-12-11T11:52:01Z","volume":"20-22","abstract":[{"lang":"eng","text":"Fault-tolerant distributed algorithms play an important role in many critical/high-availability applications. These algorithms are notoriously difficult to implement correctly, due to asynchronous communication and the occurrence of faults, such as the network dropping messages or computers crashing. We introduce PSYNC, a domain specific language based on the Heard-Of model, which views asynchronous faulty systems as synchronous ones with an adversarial environment that simulates asynchrony and faults by dropping messages. We define a runtime system for PSYNC that efficiently executes on asynchronous networks. We formalize the relation between the runtime system and PSYNC in terms of observational refinement. The high-level lockstep abstraction introduced by PSYNC simplifies the design and implementation of fault-tolerant distributed algorithms and enables automated formal verification. We have implemented an embedding of PSYNC in the SCALA programming language with a runtime system for asynchronous networks. We show the applicability of PSYNC by implementing several important fault-tolerant distributed algorithms and we compare the implementation of consensus algorithms in PSYNC against implementations in other languages in terms of code size, runtime efficiency, and verification."}],"publication_status":"published","month":"01","department":[{"_id":"ToHe"}],"language":[{"iso":"eng"}],"oa":1,"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Dragoi C, Henzinger TA, Zufferey D. 2016.

We study the behavior of such timed I/O systems in the presence of uncertain inputs and formalize their robustness using the analytic notion of Lipschitz continuity: a timed I/O system is K-(Lipschitz) robust if the perturbation in its output is at most K times the perturbation in its input. We quantify input and output perturbation using similarity functions over timed words such as the timed version of the Manhattan distance and the Skorokhod distance. We consider two models of timed I/O systems — timed transducers and asynchronous sequential circuits. We show that K-robustness of timed transducers can be decided in polynomial space under certain conditions. For asynchronous sequential circuits, we reduce K-robustness w.r.t. timed Manhattan distances to K-robustness of discrete letter-to-letter transducers and show PSpace-completeness of the problem."}],"intvolume":"      9583","volume":9583,"date_created":"2018-12-11T11:52:32Z","author":[{"first_name":"Thomas A","orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","last_name":"Henzinger"},{"first_name":"Jan","id":"2FC5DA74-F248-11E8-B48F-1D18A9856A87","full_name":"Otop, Jan","last_name":"Otop"},{"first_name":"Roopsha","last_name":"Samanta","full_name":"Samanta, Roopsha","id":"3D2AAC08-F248-11E8-B48F-1D18A9856A87"}],"day":"01","scopus_import":1,"title":"Lipschitz robustness of timed I/O systems","oa_version":"Preprint","ec_funded":1,"conference":{"name":"VMCAI: Verification, Model Checking and Abstract Interpretation","start_date":"2016-01-17","end_date":"2016-01-19","location":"St. Petersburg, FL, USA"},"acknowledgement":"This research was supported in part by the European Research Council (ERC) under grant 267989 (QUAREM), by the Austrian Science Fund (FWF) under grants S11402-N23 (RiSE) and Z211-N23 (Wittgenstein Award), and by the National Science Centre (NCN), Poland under grant 2014/15/D/ST6/04543.","date_published":"2016-01-01T00:00:00Z","project":[{"call_identifier":"FP7","grant_number":"267989","name":"Quantitative Reactive Modeling","_id":"25EE3708-B435-11E9-9278-68D0E5697425"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"The Wittgenstein Prize","grant_number":"Z211"},{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering"}],"status":"public","publist_id":"5647","year":"2016","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1506.01233"}],"quality_controlled":"1","page":"250 - 267","date_updated":"2021-01-12T06:51:23Z","_id":"1526","type":"conference","doi":"10.1007/978-3-662-49122-5_12","alternative_title":["LNCS"],"publisher":"Springer"}]
