A cheaply obtained guess can be useful in several applications. Not only can the guessed strategy be applied as best-effort in cases where the game’s huge size prohibits rigorous approaches, but it can also increase the scalability of rigorous LTL synthesis in several ways. Firstly, checking whether a guessed strategy is winning is easier than constructing one. Secondly, even if the guess is wrong in some places, it can be fixed by strategy iteration faster than constructing one from scratch. Thirdly, the guess can be used in on-the-fly approaches to prioritize exploration in the most fruitful directions.\r\nIn contrast to previous works, we (i) reflect the highly structured logical information in game’s states, the so-called semantic labelling, coming from the recent LTL-to-automata translations, and (ii) learn to reflect it properly by learning from previously solved games, bringing the solving process closer to human-like reasoning."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14259","intvolume":" 13964","ddc":["000"],"status":"public","title":"Guessing winning policies in LTL synthesis by semantic learning","file":[{"success":1,"checksum":"ed66278b61bb869e1baba3d9b9081271","date_updated":"2023-09-06T08:25:50Z","date_created":"2023-09-06T08:25:50Z","file_id":"14276","relation":"main_file","creator":"dernst","content_type":"application/pdf","file_size":428354,"access_level":"open_access","file_name":"2023_LNCS_CAV_Kretinsky.pdf"}],"oa_version":"Published Version","scopus_import":"1","has_accepted_license":"1","article_processing_charge":"Yes (in subscription journal)","day":"17","citation":{"short":"J.

Given a PRR and a time limit κ, we consider the tail probability Pr[T≥κ], i.e., the probability that the randomized runtime T of the PRR exceeds κ. Our focus is the formal analysis of tail bounds that aims at finding a tight asymptotic upper bound u≥Pr[T≥κ]. To address this problem, the classical and most well-known approach is the cookbook method by Karp (JACM 1994), while other approaches are mostly limited to deriving tail bounds of specific PRRs via involved custom analysis.\r\nIn this work, we propose a novel approach for deriving the common exponentially-decreasing tail bounds for PRRs whose preprocessing time and random passed sizes observe discrete or (piecewise) uniform distribution and whose recursive call is either a single procedure call or a divide-and-conquer. We first establish a theoretical approach via Markov’s inequality, and then instantiate the theoretical approach with a template-based algorithmic approach via a refined treatment of exponentiation. Experimental evaluation shows that our algorithmic approach is capable of deriving tail bounds that are (i) asymptotically tighter than Karp’s method, (ii) match the best-known manually-derived asymptotic tail bound for QuickSelect, and (iii) is only slightly worse (with a loglogn factor) than the manually-proven optimal asymptotic tail bound for QuickSort. Moreover, our algorithmic approach handles all examples (including realistic PRRs such as QuickSort, QuickSelect, DiameterComputation, etc.) in less than 0.1 s, showing that our approach is efficient in practice."}],"type":"conference","alternative_title":["LNCS"],"date_published":"2023-07-17T00:00:00Z","publication":"Computer Aided Verification","citation":{"short":"Y.

More precisely, we develop a new framework for template-based synthesis of certificates as affine distributional and inductive invariants for safety objectives in MDPs. We provide two algorithms within this framework. One can only synthesize memoryless strategies, but has relative completeness guarantees, while the other can synthesize general strategies. The runtime complexity of both algorithms is in PSPACE.

Stochastic games are standard models in control, verification, and synthesis of stochastic reactive systems that exhibit both randomness as well as controllable and adversarial non-determinism. Lexicographic order allows one to consider multiple objectives with a strict preference order. To the best of our knowledge, stochastic games with lexicographic objectives have not been studied before. For a mixture of reachability and safety objectives, we show that deterministic lexicographically optimal strategies exist and memory is only required to remember the already satisfied and violated objectives. For a constant number of objectives, we show that the relevant decision problem is in NP∩coNP, matching the current known bound for single objectives; and in general the decision problem is PSPACE-hard and can be solved in NEXPTIME∩coNEXPTIME. We present an algorithm that computes the lexicographically optimal strategies via a reduction to the computation of optimal strategies in a sequence of single-objectives games. For omega-regular objectives, we restrict our analysis to one-player games, also known as Markov decision processes. We show that lexicographically optimal strategies exist and need either randomization or finite memory. We present an algorithm that solves the relevant decision problem in polynomial time. We have implemented our algorithms and report experimental results on various case studies.","lang":"eng"}],"type":"journal_article","language":[{"iso":"eng"}],"doi":"10.1007/s10703-023-00411-4","isi":1,"quality_controlled":"1","project":[{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"grant_number":"ICT15-003","_id":"25892FC0-B435-11E9-9278-68D0E5697425","name":"Efficient Algorithms for Computer Aided Verification"}],"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","short":"CC BY (4.0)","image":"/images/cc_by.png"},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s10703-023-00411-4"}],"external_id":{"isi":["000946174300001"]},"oa":1,"month":"03","publication_identifier":{"eissn":["1572-8102"]},"date_updated":"2023-10-03T11:36:13Z","date_created":"2023-03-19T23:00:59Z","author":[{"full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Katoen","first_name":"Joost P","id":"4524F760-F248-11E8-B48F-1D18A9856A87","full_name":"Katoen, Joost P"},{"last_name":"Mohr","first_name":"Stefanie","full_name":"Mohr, Stefanie"},{"last_name":"Weininger","first_name":"Maximilian","full_name":"Weininger, Maximilian"},{"last_name":"Winkler","first_name":"Tobias","full_name":"Winkler, Tobias"}],"related_material":{"record":[{"relation":"earlier_version","status":"public","id":"8272"}]},"publication_status":"epub_ahead","publisher":"Springer Nature","department":[{"_id":"KrCh"}],"acknowledgement":"Tobias Winkler and Joost-Pieter Katoen are supported by the DFG RTG 2236 UnRAVeL and the innovation programme under the Marie Skłodowska-Curie grant agreement No. 101008233 (Mission).

A survey of games with incompetent players","abstract":[{"text":"Mathematical models often aim to describe a complicated mechanism in a cohesive and simple manner. However, reaching perfect balance between being simple enough or overly simplistic is a challenging task. Frequently, game-theoretic models have an underlying assumption that players, whenever they choose to execute a specific action, do so perfectly. In fact, it is rare that action execution perfectly coincides with intentions of individuals, giving rise to behavioural mistakes. The concept of incompetence of players was suggested to address this issue in game-theoretic settings. Under the assumption of incompetence, players have non-zero probabilities of executing a different strategy from the one they chose, leading to stochastic outcomes of the interactions. In this article, we survey results related to the concept of incompetence in classic as well as evolutionary game theory and provide several new results. We also suggest future extensions of the model and argue why it is important to take into account behavioural mistakes when analysing interactions among players in both economic and biological settings.","lang":"eng"}],"type":"journal_article","date_published":"2023-03-01T00:00:00Z","citation":{"apa":"Graham, T., Kleshnina, M., & Filar, J.

We study ERisk for the first time in the context of turn-based stochastic games with the total reward objective. This gives rise to an objective function that demands the control of systems in a risk-averse manner. We show that the resulting games are determined and, in particular, admit optimal memoryless deterministic strategies. This contrasts risk measures that previously have been considered in the special case of Markov decision processes and that require randomization and/or memory. We provide several results on the decidability and the computational complexity of the threshold problem, i.e. whether the optimal value of ERisk exceeds a given threshold. In the most general case, the problem is decidable subject to Shanuel’s conjecture. If all inputs are rational, the resulting threshold problem can be solved using algebraic numbers, leading to decidability via a polynomial-time reduction to the existential theory of the reals. Further restrictions on the encoding of the input allow the solution of the threshold problem in NP∩coNP. Finally, an approximation algorithm for the optimal value of ERisk is provided."}],"type":"conference","alternative_title":["LIPIcs"]},{"publication_identifier":{"eissn":["1932-6203"]},"month":"02","oa":1,"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","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"pmid":["36848357"],"isi":["000996122900022"]},"isi":1,"quality_controlled":"1","doi":"10.1371/journal.pone.0279838","language":[{"iso":"eng"}],"file_date_updated":"2023-03-07T10:26:45Z","pmid":1,"acknowledgement":"This research was supported by an Australian Government Research Training Program\r\n(RTP) Scholarship to JCM (https://www.dese.gov.au), and LB is supported by the Centre de\r\nrecherche sur le vieillissement Fellowship Program.

We define the functional response term to match empirical findings, and examine situations where metabolic theory derivations and observation diverge. The dynamical properties of the Rosenzweig-MacArthur system, encompassing the distribution of size-abundance equilibria, the scaling of period and amplitude of population cycling, and relationships between predator and prey abundances, are consistent with empirical observation.

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."}],"citation":{"chicago":"Avni, Guy, Tobias Meggendorfer, Suman Sadhukhan, Josef Tkadlec, and Dorde Zikelic. “Reachability Poorman Discrete-Bidding Games.” In Frontiers in Artificial Intelligence and Applications, 372:141–48.

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.

The capacity of a link (u, v) is determined by how much nodes u and v allocate for this link. Specifically, the input is a finite ordered sequence of packets that arrive in both directions along a link. Given (u, v) and a packet of weight x going from u to v, node u can either accept or reject the packet. If u accepts the packet, the capacity on link (u, v) decreases by x. Correspondingly, v’s capacity on (u, v) increases by x. If a node rejects the packet, this will entail a cost affinely linear in the weight of the packet. A link is “rechargeable” in the sense that the total capacity of the link has to remain constant, but the allocation of capacity at the ends of the link can depend arbitrarily on the nodes’ decisions. The goal is to minimise the sum of the capacity injected into the link and the cost of rejecting packets. We show that the problem is NP-hard, but can be approximated efficiently with a ratio of (1+ε)⋅(1+3–√) for some arbitrary ε>0.\r\n.","lang":"eng"}],"page":"576-594","publication":"SIROCCO 2023: Structural Information and Communication Complexity ","citation":{"ista":"Schmid S, Svoboda J, Yeo MX. 2023.

Here we explore how natural selection acts on mutants that have the same reproductive rate, but different population structures. In our framework, population structure is given by a graph that specifies where offspring can disperse. The invading mutant disperses offspring on a different graph than the resident wild-type. We find that more densely connected dispersal graphs tend to increase the invader’s fixation probability, but the exact relationship between structure and fixation probability is subtle. We present three main results. First, we prove that if both invader and resident are on complete dispersal graphs, then removing a single edge in the invader’s dispersal graph reduces its fixation probability. Second, we show that for certain island models higher invader’s connectivity increases its fixation probability, but the magnitude of the effect depends on the exact layout of the connections. Third, we show that for lattices the effect of different connectivity is comparable to that of different fitness: for large population size, the invader’s fixation probability is either constant or exponentially small, depending on whether it is more or less connected than the resident."}],"issue":"208","title":"Evolutionary dynamics of mutants that modify population structure","ddc":["000","570"],"status":"public","intvolume":" 20","_id":"14657","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"file_id":"14673","relation":"main_file","date_created":"2023-12-11T11:10:32Z","date_updated":"2023-12-11T11:10:32Z","success":1,"checksum":"2eefab13127c7786dbd33303c482a004","file_name":"2023_RoyalInterface_Tkadlec.pdf","access_level":"open_access","creator":"dernst","content_type":"application/pdf","file_size":1720243}],"oa_version":"Published Version","month":"11","publication_identifier":{"eissn":["1742-5662"]},"quality_controlled":"1","project":[{"grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"oa":1,"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","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"pmid":["38016637"]},"language":[{"iso":"eng"}],"doi":"10.1098/rsif.2023.0355","article_number":"20230355","file_date_updated":"2023-12-11T11:10:32Z","ec_funded":1,"publication_status":"published","publisher":"The Royal Society","department":[{"_id":"KrCh"}],"acknowledgement":"K.C. acknowledges support from the ERC CoG 863818(ForM-SMArt).

The feedback between behavior and environment can be studied with the framework of stochastic games. In stochastic games, the state of the environment can change, depending on the choices made by group members. Past work suggests that such feedback can reinforce cooperative behaviors. In particular, cooperation can evolve in stochastic games even if it is infeasible in each separate repeated game. In stochastic games, participants have an interest in conditioning their strategies on the state of the environment. Yet in many applications, precise information about the state could be scarce. Here, we study how the availability of information (or lack thereof) shapes evolution of cooperation. Already for simple examples of two state games we find surprising effects. In some cases, cooperation is only possible if there is precise information about the state of the environment. In other cases, cooperation is most abundant when there is no information about the state of the environment. We systematically analyze all stochastic games of a given complexity class, to determine when receiving information about the environment is better, neutral, or worse for evolution of cooperation."}],"title":"The effect of environmental information on evolution of cooperation in stochastic games","ddc":["000"],"status":"public","intvolume":" 14","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13258","oa_version":"Published Version","file":[{"access_level":"open_access","file_name":"2023_NatureComm_Kleshnina.pdf","content_type":"application/pdf","file_size":1601682,"creator":"dernst","relation":"main_file","file_id":"13337","checksum":"5aceefdfe76686267b93ae4fe81899f1","success":1,"date_created":"2023-07-31T11:32:36Z","date_updated":"2023-07-31T11:32:36Z"}]},{"type":"research_data_reference","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13336","year":"2023","publisher":"Zenodo","department":[{"_id":"KrCh"}],"status":"public","title":"kleshnina/stochgames_info: The effect of environmental information on evolution of cooperation in stochastic games","ddc":["000"],"related_material":{"record":[{"id":"13258","status":"public","relation":"used_in_publication"}]},"author":[{"full_name":"Kleshnina, Maria","first_name":"Maria","last_name":"Kleshnina","id":"4E21749C-F248-11E8-B48F-1D18A9856A87"}],"oa_version":"Published Version","date_created":"2023-07-31T11:30:46Z","date_updated":"2023-12-13T11:42:37Z","article_processing_charge":"No","day":"20","month":"06","main_file_link":[{"url":"https://doi.org/10.5281/zenodo.8059564","open_access":"1"}],"citation":{"ieee":"M.

Due to its good practical performance, this approximative approach is typically preferred over exact techniques, even though no practical bounds on the imprecision of the result could be given until recently. As a consequence, even the most used model checkers could return arbitrarily wrong results. Over the past decade, different works derived stopping criteria, indicating when the precision reaches the desired level, for various settings, in particular MDP with reachability, total reward, and mean payoff, and SG with reachability.In this paper, we provide the first stopping criteria for VI on SG with total reward and mean payoff, yielding the first anytime algorithms in these settings. To this end, we provide the solution in two flavours: First through a reduction to the MDP case and second directly on SG. The former is simpler and automatically utilizes any advances on MDP. The latter allows for more local computations, heading towards better practical efficiency.Our solution unifies the previously mentioned approaches for MDP and SG and their underlying ideas. To achieve this, we isolate objective-specific subroutines as well as identify objective-independent concepts. These structural concepts, while surprisingly simple, form the very essence of the unified solution."}],"type":"conference","date_published":"2023-07-01T00:00:00Z","publication":"38th Annual ACM/IEEE Symposium on Logic in Computer Science","citation":{"apa":"Kretinsky, J., Meggendorfer, T., & Weininger, M.

The goal is to get token i to vertex vi for all i= 1, . . . , n using a minimum number of swaps, where a swap exchanges the tokens on the endpoints of an edge.Token swapping on a tree, also known as “sorting with a transposition tree,” is not known to be in P nor NP-complete. We present some partial results: 1. An optimum swap sequence may need to perform a swap on a leaf vertex that has the correct token (a “happy leaf”), disproving a conjecture of Vaughan. 2. Any algorithm that fixes happy leaves—as all known approximation algorithms for the problem do—has approximation factor at least 4/3. Furthermore, the two best-known 2-approximation algorithms have approximation factor exactly 2. 3. A generalized problem—weighted coloured token swapping—is NP-complete on trees, but solvable in polynomial time on paths and stars. In this version, tokens and vertices have colours, and colours have weights. The goal is to get every token to a vertex of the same colour, and the cost of a swap is the sum of the weights of the two tokens involved."}],"type":"journal_article","language":[{"iso":"eng"}],"doi":"10.46298/DMTCS.8383","quality_controlled":"1","external_id":{"arxiv":["1903.06981"]},"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","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"publication_identifier":{"issn":["1462-7264"],"eissn":["1365-8050"]},"month":"01","volume":24,"date_updated":"2024-01-04T12:42:09Z","date_created":"2023-04-16T22:01:08Z","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"7950"}]},"author":[{"last_name":"Biniaz","first_name":"Ahmad","full_name":"Biniaz, Ahmad"},{"last_name":"Jain","first_name":"Kshitij","full_name":"Jain, Kshitij"},{"full_name":"Lubiw, Anna","last_name":"Lubiw","first_name":"Anna"},{"full_name":"Masárová, Zuzana","orcid":"0000-0002-6660-1322","id":"45CFE238-F248-11E8-B48F-1D18A9856A87","last_name":"Masárová","first_name":"Zuzana"},{"first_name":"Tillmann","last_name":"Miltzow","full_name":"Miltzow, Tillmann"},{"full_name":"Mondal, Debajyoti","last_name":"Mondal","first_name":"Debajyoti"},{"full_name":"Naredla, Anurag Murty","last_name":"Naredla","first_name":"Anurag Murty"},{"first_name":"Josef","last_name":"Tkadlec","id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1097-9684","full_name":"Tkadlec, Josef"},{"full_name":"Turcotte, Alexi","last_name":"Turcotte","first_name":"Alexi"}],"department":[{"_id":"KrCh"},{"_id":"HeEd"},{"_id":"UlWa"}],"publisher":"EPI Sciences","publication_status":"published","year":"2023","acknowledgement":"This work was begun at the University of Waterloo and was partially supported by the Natural Sciences and Engineering Council of Canada (NSERC).\r\n","file_date_updated":"2023-04-17T08:10:28Z","article_number":"9"},{"day":"01","article_processing_charge":"No","page":"309-325","publication":"27th International Conference on Financial Cryptography and Data Security","citation":{"chicago":"Bastankhah, Mahsa, Krishnendu Chatterjee, Mohammad Ali Maddah-Ali, Stefan Schmid, Jakub Svoboda, and Michelle X Yeo. “R2: Boosting Liquidity in Payment Channel Networks with Online Admission Control.” In 27th International Conference on Financial Cryptography and Data Security, 13950:309–25.

PCNs, however, face the challenge that the frequent usage of certain routes may deplete channels in one direction, and hence prevent further transactions. In order to reap the full potential of PCNs, recharging and rebalancing mechanisms are required to provision channels, as well as an admission control logic to decide which transactions to reject in case capacity is insufficient. This paper presents a formal model of this optimisation problem. In particular, we consider an online algorithms perspective, where transactions arrive over time in an unpredictable manner. Our main contributions are competitive online algorithms which come with provable guarantees over time. We empirically evaluate our algorithms on randomly generated transactions to compare the average performance of our algorithms to our theoretical bounds.

Lexicographic ranking functions provide a sound and practical approach for termination of non-probabilistic programs, and their extension to probabilistic programs is achieved via lexicographic ranking supermartingales (LexRSMs). However, LexRSMs introduced in the previous work have a limitation that impedes their automation: all of their components have to be non-negative in all reachable states. This might result in a LexRSM not existing even for simple terminating programs. Our contributions are twofold. First, we introduce a generalization of LexRSMs that allows for some components to be negative. This standard feature of non-probabilistic termination proofs was hitherto not known to be sound in the probabilistic setting, as the soundness proof requires a careful analysis of the underlying stochastic process. Second, we present polynomial-time algorithms using our generalized LexRSMs for proving a.s. termination in broad classes of linear-arithmetic programs.","lang":"eng"}],"type":"journal_article","file":[{"file_name":"2023_FormalAspectsComputing_Chatterjee.pdf","access_level":"open_access","content_type":"application/pdf","file_size":502522,"creator":"dernst","relation":"main_file","file_id":"14804","date_created":"2024-01-16T08:11:24Z","date_updated":"2024-01-16T08:11:24Z","checksum":"3bb133eeb27ec01649a9a36445d952d9","success":1}],"oa_version":"Published Version","intvolume":" 35","title":"On lexicographic proof rules for probabilistic termination","status":"public","ddc":["000"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14778","article_processing_charge":"Yes (via OA deal)","has_accepted_license":"1","day":"23","keyword":["Theoretical Computer Science","Software"],"date_published":"2023-06-23T00:00:00Z","article_type":"original","citation":{"chicago":"Chatterjee, Krishnendu, Ehsan Kafshdar Goharshady, Petr Novotný, Jiří Zárevúcky, and Dorde Zikelic. “On Lexicographic Proof Rules for Probabilistic Termination.” Formal Aspects of Computing.

This work presents the first method for providing formal reach-avoid guarantees, which combine and generalize stability and safety guarantees, with a tolerable probability threshold p in [0,1] over the infinite time horizon. Our method leverages advances in machine learning literature and it represents formal certificates as neural networks. In particular, we learn a certificate in the form of a reach-avoid supermartingale (RASM), a novel notion that we introduce in this work. Our RASMs provide reachability and avoidance guarantees by imposing constraints on what can be viewed as a stochastic extension of level sets of Lyapunov functions for deterministic systems. 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. We validate our approach on 3 stochastic non-linear reinforcement learning tasks."}],"external_id":{"arxiv":["2210.05308"]},"project":[{"call_identifier":"H2020","name":"Vigilant Algorithmic Monitoring of Software","grant_number":"101020093","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"},{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020","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"}],"quality_controlled":"1","doi":"10.1609/aaai.v37i10.26407","conference":{"end_date":"2023-02-14","start_date":"2023-02-07","location":"Washington, DC, United States","name":"AAAI: Conference on Artificial Intelligence"},"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2159-5399"],"eissn":["2374-3468"]},"month":"06","acknowledgement":"This work was supported in part by the ERC-2020-AdG 101020093, 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.","year":"2023","publisher":"Association for the Advancement of Artificial Intelligence","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"publication_status":"published","related_material":{"record":[{"relation":"earlier_version","status":"public","id":"14600"}]},"author":[{"full_name":"Zikelic, Dorde","last_name":"Zikelic","first_name":"Dorde","orcid":"0000-0002-4681-1699","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87"},{"id":"3DC22916-F248-11E8-B48F-1D18A9856A87","first_name":"Mathias","last_name":"Lechner","full_name":"Lechner, Mathias"},{"first_name":"Thomas A","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A"},{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee"}],"volume":37,"date_created":"2024-01-18T07:44:31Z","date_updated":"2024-01-22T14:08:29Z","ec_funded":1}]
