Quantization is a technique for making neural networks more efficient by running them using low-bit integer arithmetic and is therefore commonly adopted in industry. Recent work has shown that floating-point neural networks that have been verified to be robust can become vulnerable to adversarial attacks after quantization, and certification of the quantized representation is necessary to guarantee robustness. In this work, we present quantization-aware interval bound propagation (QA-IBP), a novel method for training robust QNNs. Inspired by advances in robust learning of non-quantized networks, our training algorithm computes the gradient of an abstract representation of the actual network. Unlike existing approaches, our method can handle the discrete semantics of QNNs. Based on QA-IBP, we also develop a complete verification procedure for verifying the adversarial robustness of QNNs, which is guaranteed to terminate and produce a correct answer. Compared to existing approaches, the key advantage of our verification procedure is that it runs entirely on GPU or other accelerator devices. We demonstrate experimentally that our approach significantly outperforms existing methods and establish the new state-of-the-art for training and certifying the robustness of QNNs.","lang":"eng"}],"day":"26","citation":{"ista":"Lechner M, Zikelic D, Chatterjee K, Henzinger TA, Rus D. 2023.

The game proceeds by placing a token on a vertex of a graph, and allowing the players to move it to produce an infinite path, which determines the winner or payoff of the game. Traditionally, the players alternate turns in moving the token. In \"bidding games\", however, the players have budgets and in each turn, an auction (bidding) determines which player moves the token. So far, bidding games have only been studied as full-information games. In this work we initiate the study of partial-information bidding games: we study bidding games in which a player's initial budget is drawn from a known probability distribution. We show that while for some bidding mechanisms and objectives, it is straightforward to adapt the results from the full-information setting to the partial-information setting, for others, the analysis is significantly more challenging, requires new techniques, and gives rise to interesting results. Specifically, we study games with \"mean-payoff\" objectives in combination with \"poorman\" bidding. We construct optimal strategies for a partially-informed player who plays against a fully-informed adversary. We show that, somewhat surprisingly, the \"value\" under pure strategies does not necessarily exist in such games.","lang":"eng"}],"status":"public","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"acknowledgement":"This research was supported in part by ISF grant no.1679/21, by the ERC CoG 863818 (ForM-SMArt), and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385.","_id":"14243","month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","oa":1,"title":"Bidding graph games with partially-observable budgets","article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1609/aaai.v37i5.25679"}],"scopus_import":"1","publication_identifier":{"isbn":["9781577358800"]},"project":[{"call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"},{"call_identifier":"H2020","name":"International IST Doctoral Program","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"date_updated":"2025-07-14T09:09:56Z","date_created":"2023-08-27T22:01:18Z","year":"2023","page":"5464-5471","quality_controlled":"1","volume":37,"date_published":"2023-06-27T00:00:00Z","oa_version":"Published Version","conference":{"end_date":"2023-02-14","location":"Washington, DC, United States","start_date":"2023-02-07","name":"AAAI: Conference on Artificial Intelligence"},"external_id":{"arxiv":["2211.13626"]},"author":[{"last_name":"Avni","full_name":"Avni, Guy","first_name":"Guy","orcid":"0000-0001-5588-8287","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87"},{"id":"85D7C63E-7D5D-11E9-9C0F-98C4E5697425","last_name":"Jecker","full_name":"Jecker, Ismael R","first_name":"Ismael R"},{"last_name":"Zikelic","first_name":"Dorde","full_name":"Zikelic, Dorde","orcid":"0000-0002-4681-1699","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87"}],"issue":"5","publication":"Proceedings of the 37th AAAI Conference on Artificial Intelligence","doi":"10.1609/aaai.v37i5.25679","type":"conference","language":[{"iso":"eng"}],"arxiv":1},{"acknowledgement":"We thank Daniel Hausmann and Nir Piterman for their valuable comments on an earlier version of the manuscript of our other paper [22] where we present, among other things, the parity fixpoint for 2 1/2-player games (for a slightly more general class of games) with a different and indirect proof of correctness.

The problem reduces, after automata-theoretic constructions, to finding the maximal probability of satisfying a parity condition on a (possibly hybrid) state space. While characterizing the exact satisfaction probability is open, we show that a lower bound on this probability can be obtained by (I) computing an under-approximation of the qualitative winning region, i.e., states from which the parity condition can be enforced almost surely, and (II) computing the maximal probability of reaching this qualitative winning region.\r\nThe heart of our approach is a technique to symbolically compute the under-approximation of the qualitative winning region in step (I) via a finite-state abstraction of the original system as a \r\n-player parity game. Our abstraction procedure uses only the support of the probabilistic evolution; it does not use precise numerical transition probabilities. We prove that the winning set in the abstract -player game induces an under-approximation of the qualitative winning region in the original synthesis problem, along with a policy to solve it. By combining these contributions with (a) a symbolic fixpoint algorithm to solve \r\n-player games and (b) existing techniques for reachability policy synthesis in stochastic nonlinear systems, we get an abstraction-based algorithm for finding a lower bound on the maximal satisfaction probability.\r\nWe have implemented the abstraction-based algorithm in Mascot-SDS, where we combined the outlined abstraction step with our tool Genie (Majumdar et al., 2023) that solves \r\n-player parity games (through a reduction to Rabin games) more efficiently than existing algorithms. We evaluated our implementation on the nonlinear model of a perturbed bistable switch from the literature. We show empirically that the lower bound on the winning region computed by our approach is precise, by comparing against an over-approximation of the qualitative winning region. Moreover, our implementation outperforms a recently proposed tool for solving this problem by a large margin."}],"status":"public","article_number":"101430","ec_funded":1,"author":[{"full_name":"Majumdar, Rupak","first_name":"Rupak","last_name":"Majumdar"},{"last_name":"Mallik","full_name":"Mallik, Kaushik","first_name":"Kaushik","id":"0834ff3c-6d72-11ec-94e0-b5b0a4fb8598","orcid":"0000-0001-9864-7475"},{"last_name":"Schmuck","full_name":"Schmuck, Anne Kathrin","first_name":"Anne Kathrin"},{"last_name":"Soudjani","full_name":"Soudjani, Sadegh","first_name":"Sadegh"}],"publication":"Nonlinear Analysis: Hybrid Systems","date_published":"2023-09-27T00:00:00Z","oa_version":"Published Version","external_id":{"isi":["001093188100001"],"arxiv":["2101.00834"]},"type":"journal_article","language":[{"iso":"eng"}],"arxiv":1,"publisher":"Elsevier","doi":"10.1016/j.nahs.2023.101430","main_file_link":[{"url":"https://doi.org/10.1016/j.nahs.2023.101430","open_access":"1"}],"scopus_import":"1","publication_identifier":{"issn":["1751-570X"]},"article_processing_charge":"No","isi":1,"volume":51,"project":[{"call_identifier":"H2020","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","name":"Vigilant Algorithmic Monitoring of Software","grant_number":"101020093"}],"date_updated":"2023-12-13T12:58:56Z","year":"2023","date_created":"2023-10-08T22:01:15Z","quality_controlled":"1"},{"citation":{"ieee":"E.

They are finite automata with nodes labeled with hypernode logic formulas and transitions labeled with actions. A hypernode logic formula specifies relations between sequences of variable values in different system executions. Unlike HyperLTL, hypernode logic takes an asynchronous view on execution traces by constraining the values and the order of value changes of each variable without correlating the timing of the changes. Different execution traces are synchronized solely through the transitions of hypernode automata. Hypernode automata naturally combine asynchronicity at the node level with synchronicity at the transition level. We show that the model-checking problem for hypernode automata is decidable over action-labeled Kripke structures, whose actions induce transitions of the specification automata. For this reason, hypernode automaton is a suitable formalism for specifying and verifying asynchronous hyperproperties, such as declassifying observational determinism in multi-threaded programs."}],"ec_funded":1,"alternative_title":["LIPIcs"],"department":[{"_id":"ToHe"}],"acknowledgement":"This work was supported in part by the Austrian Science Fund (FWF) SFB project\r\nSpyCoDe F8502, by the FWF projects ZK-35 and W1255-N23, and by the ERC Advanced Grant\r\nVAMOS 101020093.","oa":1,"title":"Hypernode automata","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"09","_id":"14405","publication_identifier":{"isbn":["9783959772990"],"issn":["18688969"]},"scopus_import":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"article_processing_charge":"Yes","volume":279,"file":[{"file_size":795790,"creator":"dernst","relation":"main_file","checksum":"215765e40454d806174ac0a223e8d6fa","date_created":"2023-10-09T07:42:45Z","content_type":"application/pdf","file_id":"14413","success":1,"access_level":"open_access","date_updated":"2023-10-09T07:42:45Z","file_name":"2023_LIPcs_Bartocci.pdf"}],"quality_controlled":"1","date_created":"2023-10-08T22:01:16Z","year":"2023","date_updated":"2023-10-09T07:43:44Z","project":[{"_id":"62781420-2b32-11ec-9570-8d9b63373d4d","grant_number":"101020093","name":"Vigilant Algorithmic Monitoring of Software","call_identifier":"H2020"}],"publication":"34th International Conference on Concurrency Theory","ddc":["000"],"author":[{"first_name":"Ezio","full_name":"Bartocci, Ezio","last_name":"Bartocci"},{"orcid":"0000-0002-2985-7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","first_name":"Thomas A","full_name":"Henzinger, Thomas A"},{"id":"41BCEE5C-F248-11E8-B48F-1D18A9856A87","last_name":"Nickovic","first_name":"Dejan","full_name":"Nickovic, Dejan"},{"first_name":"Ana","full_name":"Oliveira da Costa, Ana","last_name":"Oliveira da Costa","id":"f347ec37-6676-11ee-b395-a888cb7b4fb4","orcid":"0000-0002-8741-5799"}],"conference":{"start_date":"2023-09-19","name":"CONCUR: Conference on Concurrency Theory","end_date":"2023-09-22","location":"Antwerp, Belgium"},"oa_version":"Published Version","external_id":{"arxiv":["2305.02836"]},"date_published":"2023-09-01T00:00:00Z","arxiv":1,"language":[{"iso":"eng"}],"file_date_updated":"2023-10-09T07:42:45Z","type":"conference","doi":"10.4230/LIPIcs.CONCUR.2023.21","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik"},{"title":"Phenotype control of partially specified boolean networks","oa":1,"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14411","month":"09","alternative_title":["LNBI"],"acknowledgement":"This work was supported by the Czech Foundation grant No. GA22-10845S, Grant Agency of Masaryk University grant No. MUNI/G/1771/2020, and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 101034413.","department":[{"_id":"ToHe"}],"status":"public","abstract":[{"text":"Partially specified Boolean networks (PSBNs) represent a promising framework for the qualitative modelling of biological systems in which the logic of interactions is not completely known.

To complement design-time bias mitigation measures, runtime verification techniques have been introduced recently to monitor the algorithmic fairness of deployed systems. Previous monitoring techniques assume full observability of the states of the (unknown) monitored system. Moreover, they can monitor only fairness properties that are specified as arithmetic expressions over the probabilities of different events. In this work, we extend fairness monitoring to systems modeled as partially observed Markov chains (POMC), and to specifications containing arithmetic expressions over the expected values of numerical functions on event sequences. The only assumptions we make are that the underlying POMC is aperiodic and starts in the stationary distribution, with a bound on its mixing time being known. These assumptions enable us to estimate a given property for the entire distribution of possible executions of the monitored POMC, by observing only a single execution. Our monitors observe a long run of the system and, after each new observation, output updated PAC-estimates of how fair or biased the system is. The monitors are computationally lightweight and, using a prototype implementation, we demonstrate their effectiveness on several real-world examples.","lang":"eng"}],"status":"public","acknowledgement":"This work is supported by the European Research Council under Grant No.: ERC-2020-AdG 101020093.","department":[{"_id":"ToHe"}],"alternative_title":["LNCS"],"month":"10","_id":"14454","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","title":"Monitoring algorithmic fairness under partial observations","oa":1},{"publisher":"IOS Press","doi":"10.3233/FAIA230264","type":"conference","file_date_updated":"2023-11-13T10:16:10Z","arxiv":1,"language":[{"iso":"eng"}],"date_published":"2023-09-28T00:00:00Z","conference":{"location":"Krakow, Poland","end_date":"2023-10-04","name":"ECAI: European Conference on Artificial Intelligence","start_date":"2023-09-30"},"license":"https://creativecommons.org/licenses/by-nc/4.0/","external_id":{"arxiv":["2307.15218"]},"oa_version":"Published Version","author":[{"full_name":"Avni, Guy","first_name":"Guy","last_name":"Avni","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5588-8287"},{"full_name":"Meggendorfer, Tobias","first_name":"Tobias","last_name":"Meggendorfer","orcid":"0000-0002-1712-2165","id":"b21b0c15-30a2-11eb-80dc-f13ca25802e1"},{"last_name":"Sadhukhan","first_name":"Suman","full_name":"Sadhukhan, Suman"},{"id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1097-9684","last_name":"Tkadlec","first_name":"Josef","full_name":"Tkadlec, Josef"},{"last_name":"Zikelic","first_name":"Dorde","full_name":"Zikelic, Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4681-1699"}],"ddc":["000"],"publication":"Frontiers in Artificial Intelligence and Applications","project":[{"call_identifier":"H2020","grant_number":"665385","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818"}],"date_updated":"2025-07-14T09:09:57Z","year":"2023","date_created":"2023-11-12T23:00:56Z","page":"141-148","quality_controlled":"1","file":[{"file_size":501011,"creator":"dernst","relation":"main_file","checksum":"1390ca38480fa4cf286b0f1a42e8c12f","date_created":"2023-11-13T10:16:10Z","file_id":"14529","content_type":"application/pdf","success":1,"access_level":"open_access","date_updated":"2023-11-13T10:16:10Z","file_name":"2023_FAIA_Avni.pdf"}],"volume":372,"article_processing_charge":"No","tmp":{"short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png"},"scopus_import":"1","publication_identifier":{"isbn":["9781643684369"],"issn":["0922-6389"]},"month":"09","_id":"14518","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","oa":1,"title":"Reachability poorman discrete-bidding games","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"acknowledgement":"This research was supported in part by ISF grant no. 1679/21, ERC CoG 863818 (FoRM-SMArt) and the European Union’s Horizon 2020 research and innovation programme under the Marie SkłodowskaCurie Grant Agreement No. 665385.","ec_funded":1,"abstract":[{"lang":"eng","text":"We consider bidding games, a class of two-player zero-sum graph games. The game proceeds as follows. Both players have bounded budgets. A token is placed on a vertex of a graph, in each turn the players simultaneously submit bids, and the higher bidder moves the token, where we break bidding ties in favor of Player 1. Player 1 wins the game iff the token visits a designated target vertex. We consider, for the first time, poorman discrete-bidding in which the granularity of the bids is restricted and the higher bid is paid to the bank. Previous work either did not impose granularity restrictions or considered Richman bidding (bids are paid to the opponent). While the latter mechanisms are technically more accessible, the former is more appealing from a practical standpoint. Our study focuses on threshold budgets, which is the necessary and sufficient initial budget required for Player 1 to ensure winning against a given Player 2 budget. We first show existence of thresholds. In DAGs, we show that threshold budgets can be approximated with error bounds by thresholds under continuous-bidding and that they exhibit a periodic behavior. We identify closed-form solutions in special cases. We implement and experiment with an algorithm to find threshold budgets."}],"status":"public","has_accepted_license":"1","day":"28","citation":{"short":"G. Avni, T. Meggendorfer, S. Sadhukhan, J.

Our approach is based on the novel notion of stabilizing ranking supermartingales (sRSMs) that we introduce in this work. Our sRSMs overcome the limitation of methods proposed in previous works whose applicability is restricted to systems in which the stabilizing region cannot be left once entered under any control policy. We present a learning procedure that learns a control policy together with an sRSM that formally certifies probability 1 stability, both learned as neural networks. We show that this procedure can also be adapted to formally verifying that, under a given Lipschitz continuous control policy, the stochastic system stabilizes within some stabilizing region with probability 1. Our experimental evaluation shows that our learning procedure can successfully learn provably stabilizing policies in practice.","lang":"eng"}],"status":"public","ec_funded":1,"citation":{"ama":"Ansaripour M, Chatterjee K, Henzinger TA, Lechner M, Zikelic D.

However, the performance of BDD-based algorithms greatly depends on memory latency due to the reliance on large hash tables and thus, by extension, on the speed of random memory access. This hinders the full utilisation of resources available on modern CPUs, since the absolute memory latency has not improved significantly for at least a decade. In this paper, we explore several implementation techniques that improve the performance of BDD manipulation either through enhanced memory locality or by partially eliminating random memory access. On a benchmark suite of 600+ BDDs derived from real-world applications, we demonstrate runtime that is comparable or better than parallelising the same operations on eight CPU cores.

To our best knowledge, our tools are the first ones to be able to solve these problems. Furthermore, using these flexible game solvers as a back-end, we implemented a tool for computing correct-by-construction controllers for stochastic dynamical systems under LTL specifications. Our implementations use the recent theoretical result that all of these games can be solved using the same symbolic fixpoint algorithm but utilizing different, domain specific calculations of the involved predecessor operators. The main feature of our toolchain is the utilization of two programming abstractions: one to separate the symbolic fixpoint computations from the predecessor calculations, and another one to allow the integration of different BDD libraries as back-ends. In particular, we employ a multi-threaded execution of the fixpoint algorithm by using the multi-threaded BDD library Sylvan, which leads to enormous computational savings."}],"ec_funded":1,"intvolume":"     13966","citation":{"short":"R.

Our approach, like others before, leverage a notion of quasiorder to prune the search for a counterexample by discarding candidates which are subsumed by others for the quasiorder. Discarded candidates are guaranteed to not compromise the completeness of the algorithm. The novelty of our work lies in the quasiorder used to discard candidates. We introduce FORQs (family of right quasiorders) that we obtain by adapting the notion of family of right congruences put forward by Maler and Staiger in 1993. We define a FORQ-based inclusion algorithm which we prove correct and instantiate it for a specific FORQ, called the structural FORQ, induced by the Büchi automaton to the right of the inclusion sign. The resulting implementation, called FORKLIFT, scales up better than the state-of-the-art on a variety of benchmarks including benchmarks from program verification and theorem proving for word combinatorics.

In bidding games, both players have budgets, and in each turn, we hold an \"auction\" (bidding) to determine which player moves the token. In this survey, we consider several bidding mechanisms and their effect on the properties of the game. Specifically, bidding games, and in particular bidding games of infinite duration, have an intriguing equivalence with random-turn games in which in each turn, the player who moves is chosen randomly. We summarize how minor changes in the bidding mechanism lead to unexpected differences in the equivalence with random-turn games.","lang":"eng"}],"status":"public","acknowledgement":"Guy Avni: Work partially supported by the Israel Science Foundation, ISF grant agreement\r\nno 1679/21.\r\nThomas A.

Our approach solves several important problems -- it can be used to learn a control policy from scratch, to verify a reach-avoid specification for a fixed control policy, or to fine-tune a pre-trained policy if it does not satisfy the reach-avoid specification.

Our results suggest\r\nthat some form of pre-training of the policy is required for the joint\r\noptimization to repair and verify the policy successfully."}],"year":"2022","date_created":"2023-11-24T13:22:30Z","project":[{"call_identifier":"H2020","name":"Vigilant Algorithmic Monitoring of Software","grant_number":"101020093","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"},{"call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818"},{"name":"International IST Doctoral Program","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"ec_funded":1,"date_updated":"2025-07-14T09:10:00Z"},{"intvolume":"     13182","citation":{"chicago":"Bartocci, Ezio, Thomas Ferrere, Thomas A Henzinger, Dejan Nickovic, and Ana Oliveira Da Costa. “Flavors of Sequential Information Flow.” In <i>Lecture Notes in Computer Science (Including Subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)</i>, 13182:1–19.

Information-flow properties are hyperproperties, as they compare different traces of a system. Sequential information-flow properties can express changes, over time, in the information-flow constraints. For example, information-flow constraints during an initialization phase of a system may be different from information-flow constraints that are required during the operation phase. We formalize several variants of interpreting sequential information-flow constraints, which arise from different assumptions about what can be observed of the system. For this purpose, we introduce a first-order logic, called Hypertrace Logic, with both trace and time quantifiers for specifying linear-time hyperproperties. We prove that HyperLTL, which corresponds to a fragment of Hypertrace Logic with restricted quantifier prefixes, cannot specify the majority of the studied variants of sequential information flow, including all variants in which the transition between sequential phases (such as initialization and operation) happens asynchronously. Our results rely on new equivalences between sets of traces that cannot be distinguished by certain classes of formulas from Hypertrace Logic. This presents a new approach to proving inexpressiveness results for HyperLTL.","lang":"eng"}],"status":"public","alternative_title":["LNCS"],"acknowledgement":"This work was funded in part by the Wittgenstein Award Z211-N23 of the Austrian Science Fund (FWF) and by the FWF project W1255-N23.","department":[{"_id":"ToHe"}],"publication_status":"published","title":"Flavors of sequential information flow","oa":1,"_id":"10774","month":"01","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2105.02013","open_access":"1"}],"scopus_import":"1","publication_identifier":{"isbn":["9783030945824"],"issn":["03029743"],"eissn":["16113349"]},"article_processing_charge":"No","volume":13182,"project":[{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"The Wittgenstein Prize","grant_number":"Z211","call_identifier":"FWF"}],"date_updated":"2022-08-05T09:02:56Z","year":"2022","date_created":"2022-02-20T23:01:34Z","page":"1-19","quality_controlled":"1","author":[{"last_name":"Bartocci","first_name":"Ezio","full_name":"Bartocci, Ezio"},{"first_name":"Thomas","full_name":"Ferrere, Thomas","last_name":"Ferrere","orcid":"0000-0001-5199-3143","id":"40960E6E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Thomas A","full_name":"Henzinger, Thomas A","last_name":"Henzinger","orcid":"0000-0002-2985-7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Dejan","full_name":"Nickovic, Dejan","last_name":"Nickovic","id":"41BCEE5C-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ana Oliveira","full_name":"Da Costa, Ana Oliveira","last_name":"Da Costa"}],"publication":"Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)","date_published":"2022-01-14T00:00:00Z","oa_version":"Preprint","external_id":{"arxiv":["2105.02013"]},"conference":{"location":"Philadelphia, PA, United States","end_date":"2022-01-18","name":"VMCAI: Verifcation, Model Checking, and Abstract Interpretation","start_date":"2022-01-16"},"type":"conference","language":[{"iso":"eng"}],"arxiv":1,"publisher":"Springer Nature","doi":"10.1007/978-3-030-94583-1_1"}]
