The games are concurrent: in each round, the two players (player 1 and player 2) choose their moves independently and simultaneously; the current state and the two moves determine the successor state. We study concurrent games with ω-regular winning conditions specified as parity objectives.  We consider the qualitative analysis problems: the computation of the almost-sure and limit-sure winning set of states, where player 1 can ensure to win with probability 1 and with probability arbitrarily close to 1, respectively. In general the almost-sure and limit-sure winning strategies require both infinite-memory as well as infinite-precision (to describe probabilities). We study the bounded-rationality problem for qualitative analysis of concurrent parity games, where the strategy set for player 1 is restricted to bounded-resource strategies.  In terms of precision, strategies can be deterministic, uniform, finite-precision or infinite-precision;  and in terms of memory, strategies can be memoryless, finite-memory or infinite-memory. We present a precise and complete characterization of the qualitative winning sets for all combinations of classes of strategies. In particular, we show that uniform memoryless strategies are as powerful as finite-precision infinite-memory strategies, and infinite-precision memoryless strategies are as powerful as infinite-precision finite-memory strategies.  We show that the winning sets can be computed in O(n2d+3) time, where n is the size of the game structure and 2d is the number of priorities (or colors), and our algorithms are symbolic. The membership problem of whether a state belongs to a winning set can be decided in NP ∩ coNP. While this complexity is the same as for the simpler class of turn-based parity games, where in each state only one of the two players has a choice of moves, our algorithms,that are obtained by characterization of the winning sets as μ-calculus formulas, are considerably more involved than those for turn-based games."}],"publication_identifier":{"issn":["2664-1690"]},"publisher":"IST Austria","type":"technical_report","date_updated":"2023-02-23T11:22:53Z","publication_status":"published","has_accepted_license":"1","title":"Bounded rationality in concurrent parity games","department":[{"_id":"KrCh"}],"status":"public","file_date_updated":"2020-07-14T12:46:39Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"07","language":[{"iso":"eng"}],"doi":"10.15479/AT:IST-2011-0008","year":"2011","ddc":["000"]},{"ddc":["000","005"],"year":"2011","doi":"10.15479/AT:IST-2011-0007","language":[{"iso":"eng"}],"month":"07","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2020-07-14T12:46:39Z","has_accepted_license":"1","status":"public","department":[{"_id":"KrCh"}],"title":"Partial-observation stochastic games: How to win when belief fails","publication_status":"published","date_updated":"2023-02-23T11:05:48Z","type":"technical_report","publisher":"IST Austria","publication_identifier":{"issn":["2664-1690"]},"abstract":[{"lang":"eng","text":"In two-player finite-state stochastic games of partial obser- vation on graphs, in every state of the graph, the players simultaneously choose an action, and their joint actions determine a probability distri- bution over the successor states. The game is played for infinitely many rounds and thus the players construct an infinite path in the graph. We consider reachability objectives where the first player tries to ensure a target state to be visited almost-surely (i.e., with probability 1) or pos- itively (i.e., with positive probability), no matter the strategy of the second player.\r\n\r\nWe classify such games according to the information and to the power of randomization available to the players. On the basis of information, the game can be one-sided with either (a) player 1, or (b) player 2 having partial observation (and the other player has perfect observation), or two- sided with (c) both players having partial observation. On the basis of randomization, (a) the players may not be allowed to use randomization (pure strategies), or (b) they may choose a probability distribution over actions but the actual random choice is external and not visible to the player (actions invisible), or (c) they may use full randomization.\r\n\r\nOur main results for pure strategies are as follows: (1) For one-sided games with player 2 perfect observation we show that (in contrast to full randomized strategies) belief-based (subset-construction based) strate- gies are not sufficient, and present an exponential upper bound on mem- ory both for almost-sure and positive winning strategies; we show that the problem of deciding the existence of almost-sure and positive winning strategies for player 1 is EXPTIME-complete and present symbolic algo- rithms that avoid the explicit exponential construction. (2) For one-sided games with player 1 perfect observation we show that non-elementary memory is both necessary and sufficient for both almost-sure and posi- tive winning strategies. (3) We show that for the general (two-sided) case finite-memory strategies are sufficient for both positive and almost-sure winning, and at least non-elementary memory is required. We establish the equivalence of the almost-sure winning problems for pure strategies and for randomized strategies with actions invisible. Our equivalence re- sult exhibit serious flaws in previous results in the literature: we show a non-elementary memory lower bound for almost-sure winning whereas an exponential upper bound was previously claimed."}],"author":[{"full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","last_name":"Chatterjee","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Laurent","last_name":"Doyen","full_name":"Doyen, Laurent"}],"citation":{"ama":"Chatterjee K, Doyen L. <i>Partial-Observation Stochastic Games: How to Win When Belief Fails</i>.

We also consider the important special case of turn-based stochastic games where players make moves in turns, rather than concurrently. We study concurrent games with ω-regular winning conditions specified as parity objectives. The value for player 1 for a parity objective is the maximal probability with which the player can guarantee the satisfaction of the objective against all strategies of the opponent. We study the problem of continuity and robustness of the value function in concurrent and turn-based stochastic parity games with respect to imprecision in the transition probabilities. We present quantitative bounds on the difference of the value function (in terms of the imprecision of the transition probabilities) and show the value continuity for structurally equivalent concurrent games (two games are structurally equivalent if the support of the transition func- tion is same and the probabilities differ). We also show robustness of optimal strategies for structurally equivalent turn-based stochastic parity games. Finally we show that the value continuity property breaks without the structurally equivalent assumption (even for Markov chains) and show that our quantitative bound is asymptotically optimal. Hence our results are tight (the assumption is both necessary and sufficient) and optimal (our quantitative bound is asymptotically optimal).","lang":"eng"}],"author":[{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","last_name":"Chatterjee","orcid":"0000-0002-4561-241X"}],"citation":{"short":"K.

We introduce and investigate the extension of temporal logics with quantitative atomic assertions, aiming for a general and flexible framework for quantitative-oriented specifications. In the heart of quantitative objectives lies the accumulation of values along a computation. It is either the accumulated summation, as with the energy objectives, or the accumulated average, as with the mean-payoff objectives. We investigate the extension of temporal logics with the prefix-accumulation assertions Sum(v) ≥ c and Avg(v) ≥ c, where v is a numeric variable of the system, c is a constant rational number, and Sum(v) and Avg(v) denote the accumulated sum and average of the values of v from the beginning of the computation up to the current point of time. We also allow the path-accumulation assertions LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring to the average value along an entire computation. We study the border of decidability for extensions of various temporal logics. In particular, we show that extending the fragment of CTL that has only the EX, EF, AX, and AG temporal modalities by prefix-accumulation assertions and extending LTL with path-accumulation assertions, result in temporal logics whose model-checking problem is decidable. The extended logics allow to significantly extend the currently known energy and mean-payoff objectives. Moreover, the prefix-accumulation assertions may be refined with “controlled-accumulation”, allowing, for example, to specify constraints on the average waiting time between a request and a grant. On the negative side, we show that the fragment we point to is, in a sense, the maximal logic whose extension with prefix-accumulation assertions permits a decidable model-checking procedure. Extending a temporal logic that has the EG or EU modalities, and in particular CTL and LTL, makes the problem undecidable."}],"author":[{"id":"31E297B6-F248-11E8-B48F-1D18A9856A87","first_name":"Udi","last_name":"Boker","full_name":"Boker, Udi"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu"},{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","first_name":"Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger"},{"last_name":"Kupferman","first_name":"Orna","full_name":"Kupferman, Orna"}],"ec_funded":1,"related_material":{"record":[{"id":"2038","relation":"later_version","status":"public"},{"relation":"later_version","status":"public","id":"3356"}]},"pubrep_id":"21","date_published":"2011-04-04T00:00:00Z","_id":"5385","date_created":"2018-12-12T11:39:02Z"},{"ddc":["000"],"year":"2011","doi":"10.15479/AT:IST-2011-0002","language":[{"iso":"eng"}],"month":"03","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2020-07-14T12:46:41Z","status":"public","title":"Enforcing topological constraints in random field image segmentation","has_accepted_license":"1","department":[{"_id":"ChLa"}],"publication_status":"published","date_updated":"2023-02-23T11:22:48Z","type":"technical_report","publisher":"IST Austria","publication_identifier":{"issn":["2664-1690"]},"author":[{"id":"3E92416E-F248-11E8-B48F-1D18A9856A87","full_name":"Chen, Chao","first_name":"Chao","last_name":"Chen"},{"last_name":"Freedman","first_name":"Daniel","full_name":"Freedman, Daniel"},{"orcid":"0000-0001-8622-7887","last_name":"Lampert","first_name":"Christoph","full_name":"Lampert, Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87"}],"abstract":[{"text":"We introduce TopoCut: a new way to integrate knowledge about topological properties (TPs) into random field image segmentation model.

In sorting the motor behavior by the clockwise bias, we find that the distributions of the clockwise (CW) and counterclockwise (CCW) intervals are either exponential or nonexponential with long tails. At low bias, CW intervals are exponentially distributed and CCW intervals exhibit long tails. At intermediate CW bias (0.5) both CW and CCW intervals are mainly exponentially distributed. A simple model suggests that these two distinct switching behaviors are governed by the presence of signaling noise within the chemotaxis network. Low noise yields exponentially distributed intervals, whereas large noise yields nonexponential behavior with long tails. These drastically different motor statistics may play a role in optimizing bacterial behavior for a wide range of environmental conditions."}],"issue":"10","publication_status":"published","intvolume":"       101","type":"journal_article","date_updated":"2021-04-16T11:54:49Z","doi":"10.1016/j.bpj.2011.09.040","year":"2011","month":"11","language":[{"iso":"eng"}]},{"issue":"5","author":[{"last_name":"Hsieh","first_name":"Tzung-Fu","full_name":"Hsieh, Tzung-Fu"},{"full_name":"Shin, Juhyun","last_name":"Shin","first_name":"Juhyun"},{"full_name":"Uzawa, Rie","last_name":"Uzawa","first_name":"Rie"},{"full_name":"Silva, Pedro","last_name":"Silva","first_name":"Pedro"},{"full_name":"Cohen, Stephanie","last_name":"Cohen","first_name":"Stephanie"},{"last_name":"Bauer","first_name":"Matthew J.","full_name":"Bauer, Matthew J."},{"last_name":"Hashimoto","first_name":"Meryl","full_name":"Hashimoto, Meryl"},{"last_name":"Kirkbride","first_name":"Ryan C.","full_name":"Kirkbride, Ryan C."},{"first_name":"John J.","last_name":"Harada","full_name":"Harada, John J."},{"first_name":"Daniel","orcid":"0000-0002-0123-8649","last_name":"Zilberman","full_name":"Zilberman, Daniel","id":"6973db13-dd5f-11ea-814e-b3e5455e9ed1"},{"full_name":"Fischer, Robert L.","last_name":"Fischer","first_name":"Robert L."}],"abstract":[{"lang":"eng","text":"Imprinted genes are expressed primarily or exclusively from either the maternal or paternal allele, a phenomenon that occurs in flowering plants and mammals.

Currently, only 11 imprinted A. thaliana genes are known. Here, we use extensive sequencing of cDNA libraries to identify 9 paternally expressed and 34 maternally expressed imprinted genes in A. thaliana endosperm that are regulated by the DNA-demethylating glycosylase DEMETER, the DNA methyltransferase MET1, and/or the core Polycomb group protein FIE. These genes encode transcription factors, proteins involved in hormone signaling, components of the ubiquitin protein degradation pathway, regulators of histone and DNA methylation, and small RNA pathway proteins. We also identify maternally expressed genes that may be regulated by unknown mechanisms or deposited from maternal tissues. We did not detect any imprinted genes in the embryo.

Overfishing has caused mean annual catches of the European spiny lobster (Palinurus elephas) to decrease alarmingly along its distribution area. In this context, there is a need for comprehensive studies to evaluate the genetic health of the exploited populations. The present work is based on a set of 10 nuclear markers amplified in 331 individuals from 10 different localities covering most of P. elephas distribution area. Samples from Atlantic and Mediterranean basins showed small but significant differences, indicating that P. elephas populations do not behave as a single panmictic unit but form two partially-overlapping groups. Despite intense overfishing, our dataset did not recover a recent bottleneck signal, and showed a large and stable historical effective size instead. This result could be accounted for by specific life history traits (reproduction and longevity) and the limitations of molecular markers in covering very recent timescales for non temporal samples. Our study emphasizes the necessity of integrating information on effective population sizes and life history parameters when evaluating population connectivity levels from genetic data.","lang":"eng"}],"author":[{"id":"3F0E2A22-F248-11E8-B48F-1D18A9856A87","first_name":"Ferran","last_name":"Palero","orcid":"0000-0002-0343-8329","full_name":"Palero, Ferran"},{"last_name":"Abello","first_name":"Pere","full_name":"Abello, Pere"},{"last_name":"Macpherson","first_name":"Enrique","full_name":"Macpherson, Enrique"},{"first_name":"Mark","last_name":"Beaumont","full_name":"Beaumont, Mark"},{"full_name":"Pascual, Marta","first_name":"Marta","last_name":"Pascual"}],"day":"12","citation":{"short":"F.

The analysis of biological high content images often requires segmentation as a first step. We propose ilastik as an easy-to-use tool which allows the user without expertise in image processing to perform segmentation and classification in a unified way. ilastik learns from labels provided by the user through a convenient mouse interface. Based on these labels, ilastik infers a problem specific segmentation. A random forest classifier is used in the learning step, in which each pixel's neighborhood is characterized by a set of generic (nonlinear) features. ilastik supports up to three spatial plus one spectral dimension and makes use of all dimensions in the feature calculation. ilastik provides realtime feedback that enables the user to interactively refine the segmentation result and hence further fine-tune the classifier. An uncertainty measure guides the user to ambiguous regions in the images. Real time performance is achieved by multi-threading which fully exploits the capabilities of modern multi-core machines. Once a classifier has been trained on a set of representative images, it can be exported and used to automatically process a very large number of images (e.g. using the CellProfiler pipeline). ilastik is an open source project and released under the BSD license at www.ilastik.org."}]},{"publist_id":"3276","external_id":{"arxiv":["1104.2909"]},"project":[{"name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","call_identifier":"FWF"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"publisher":"Springer","status":"public","department":[{"_id":"KrCh"}],"title":"Energy and mean-payoff parity Markov Decision Processes","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"28","citation":{"ista":"Chatterjee K, Doyen L. 2011.

We consider two different objectives, namely, expectation and satisfaction objectives. Given an MDP with k reward functions, in the expectation objective the goal is to maximize the expected limit-average value, and in the satisfaction objective the goal is to maximize the probability of runs such that the limit-average value stays above a given vector. We show that under the expectation objective, in contrast to the single-objective case, both randomization and memory are necessary for strategies, and that finite-memory randomized strategies are sufficient. Under the satisfaction objective, in contrast to the single-objective case, infinite memory is necessary for strategies, and that randomized memoryless strategies are sufficient for epsilon-approximation, for all epsilon&gt;;0. We further prove that the decision problems for both expectation and satisfaction objectives can be solved in polynomial time and the trade-off curve (Pareto curve) can be epsilon-approximated in time polynomial in the size of the MDP and 1/epsilon, and exponential in the number of reward functions, for all epsilon&gt;;0. Our results also reveal flaws in previous work for MDPs with multiple mean-payoff functions under the expectation objective, correct the flaws and obtain improved results.","lang":"eng"}],"ec_funded":1,"author":[{"first_name":"Tomáš","last_name":"Brázdil","full_name":"Brázdil, Tomáš"},{"last_name":"Brožek","first_name":"Václav","full_name":"Brožek, Václav"},{"last_name":"Chatterjee","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Forejt","first_name":"Vojtěch","full_name":"Forejt, Vojtěch"},{"first_name":"Antonín","last_name":"Kučera","full_name":"Kučera, Antonín"}],"date_updated":"2021-01-12T07:42:49Z","type":"conference","publisher":"IEEE","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"KrCh"}],"status":"public","title":"Two views on multiple mean payoff objectives in Markov Decision Processes","publication_status":"published","language":[{"iso":"eng"}],"month":"06","project":[{"name":"Modern Graph Algorithmic Techniques in Formal Verification","call_identifier":"FWF","grant_number":"P 23499-N23","_id":"2584A770-B435-11E9-9278-68D0E5697425"},{"name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"S 11407_N23"},{"call_identifier":"FP7","grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"year":"2011","publist_id":"3275","doi":"10.1109/LICS.2011.10"},{"project":[{"name":"Rigorous Systems Engineering","call_identifier":"FWF","grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425"}],"external_id":{"arxiv":["1101.1727"]},"publist_id":"3274","publisher":"Springer","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Finitary languages","department":[{"_id":"KrCh"}],"status":"public","oa":1,"citation":{"apa":"Chatterjee, K., &#38; Fijalkow, N.

Every omega-regular condition can be decomposed into a safety part and a liveness part. The liveness part ensures that something good happens &quot;eventually&quot;. Finitary liveness was proposed by Alur and Henzinger as a stronger formulation of liveness. It requires that there exists an unknown, fixed bound b such that something good happens within b transitions. In this work we consider automata with finitary acceptance conditions defined by finitary Buchi, parity and Streett languages. We study languages expressible by such automata: we give their topological complexity and present a regular-expression characterization. We compare the expressive power of finitary automata and give optimal algorithms for classical decisions questions. We show that the finitary languages are Sigma 2-complete; we present a complete picture of the expressive power of various classes of automata with finitary and infinitary acceptance conditions; we show that the languages defined by finitary parity automata exactly characterize the star-free fragment of omega B-regular languages; and we show that emptiness is NLOGSPACE-complete and universality as well as language inclusion are PSPACE-complete for finitary parity and Streett automata.","lang":"eng"}],"_id":"3347","conference":{"start_date":"2011-05-26","location":"Tarragona, Spain","end_date":"2011-05-31","name":"LATA: Language and Automata Theory and Applications"},"date_created":"2018-12-11T12:02:48Z","date_published":"2011-06-16T00:00:00Z","scopus_import":1},{"type":"conference","date_updated":"2021-01-12T07:42:50Z","publisher":"Springer","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","publication_status":"published","title":"Synthesis of memory efficient real time controllers for safety objectives","status":"public","department":[{"_id":"KrCh"}],"language":[{"iso":"eng"}],"month":"01","project":[{"_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","call_identifier":"FWF","name":"Rigorous Systems Engineering"}],"doi":"10.1145/1967701.1967734","publist_id":"3273","year":"2011","oa_version":"Submitted Version","page":"221 - 230","_id":"3348","conference":{"start_date":"2011-04-12","location":"Chicago, USA","name":"HSCC: Hybrid Systems - Computation and Control","end_date":"2011-04-14"},"date_created":"2018-12-11T12:02:49Z","main_file_link":[{"url":"http://arxiv.org/abs/1101.5842","open_access":"1"}],"date_published":"2011-01-31T00:00:00Z","scopus_import":1,"oa":1,"citation":{"ieee":"K.

The problem is solved by obtaining winning strategies in the setting of concurrent two-player timed automaton games with safety objectives. To prevent a player from winning by blocking time, we restrict each player to strategies that ensure that the player cannot be responsible for causing a zeno run. We construct winning strategies for the controller which require access only to (1) the system clocks (thus, controllers which require their own internal infinitely precise clocks are not necessary), and (2) a linear (in the number of clocks) number of memory bits. Precisely, we show that for safety objectives, a memory of size (3 · |C|+lg(|C|+1)) bits suffices for winning controller strategies, where C is the set of clocks of the timed automaton game, significantly improving the previous known exponential bound. We also settle the open question of whether winning region controller strategies require memory for safety objectives by showing with an example the necessity of memory for region strategies to win for safety objectives."}],"quality_controlled":"1"},{"publication_status":"published","status":"public","title":"A reduction from parity games to simple stochastic games","intvolume":"        54","department":[{"_id":"KrCh"}],"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","publisher":"EPTCS","type":"conference","date_updated":"2021-01-12T07:42:51Z","doi":"10.4204/EPTCS.54.6","year":"2011","publist_id":"3272","project":[{"name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","call_identifier":"FWF"}],"month":"06","language":[{"iso":"eng"}],"date_published":"2011-06-04T00:00:00Z","scopus_import":1,"main_file_link":[{"url":"http://arxiv.org/abs/1106.1232","open_access":"1"}],"alternative_title":["EPTCS"],"date_created":"2018-12-11T12:02:49Z","oa_version":"Submitted Version","page":"74 - 86","volume":54,"conference":{"name":"GandALF: Games, Automata, Logic, and Formal Verification","end_date":"2011-06-17","start_date":"2011-06-15","location":"Minori, Italy"},"_id":"3349","author":[{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu"},{"last_name":"Fijalkow","first_name":"Nathanaël","full_name":"Fijalkow, Nathanaël"}],"abstract":[{"text":"Games on graphs provide a natural model for reactive non-terminating systems.
