On the basis of the information available to the players these games can be classified as follows: (a) partial-observation (both players have partial view of the game); (b) one-sided partial-observation (one player has partial-observation and the other player has complete-observation); and (c) complete-observation (both players have com- plete view of the game). We survey the complexity results for the problem of de- ciding the winner in various classes of partial-observation games with ω-regular winning conditions specified as parity objectives. We present a reduction from the class of parity objectives that depend on sequence of states of the game to the sub-class of parity objectives that only depend on the sequence of observations. We also establish that partial-observation acyclic games are PSPACE-complete.","lang":"eng"}],"department":[{"_id":"KrCh"}],"file":[{"creator":"dernst","date_updated":"2020-07-14T12:46:18Z","file_size":142836,"date_created":"2020-05-19T16:29:04Z","file_id":"7872","access_level":"open_access","content_type":"application/pdf","file_name":"2010_LPAR_Chatterjee.pdf","checksum":"770e86e5d78c56fddb4786a8da7ef126","relation":"main_file"}],"month":"12","citation":{"ieee":"K.

In energy games, the objective is to ensure that the running sum of weights is always nonnegative. Generalized mean-payoff and energy games replace individual weights by tuples, and the limit average (resp. running sum) of each coordinate must be (resp. remain) nonnegative. These games have applications in the synthesis of resource-bounded processes with multiple resources. We prove the finite-memory determinacy of generalized energy games and show the inter- reducibility of generalized mean-payoff and energy games for finite-memory strategies. We also improve the computational complexity for solving both classes of games with finite-memory strategies: while the previously best known upper bound was EXPSPACE, and no lower bound was known, we give an optimal coNP-complete bound. For memoryless strategies, we show that the problem of deciding the existence of a winning strategy for the protagonist is NP-complete."}],"intvolume":"         8","file_date_updated":"2020-07-14T12:46:18Z","publication_status":"published","month":"12","department":[{"_id":"KrCh"},{"_id":"ToHe"}],"file":[{"creator":"system","date_updated":"2020-07-14T12:46:18Z","date_created":"2018-12-12T10:15:27Z","file_size":178278,"file_id":"5147","content_type":"application/pdf","access_level":"open_access","file_name":"IST-2012-59-v1+1_Generalized_mean-payoff_and_energy_games.pdf","checksum":"1caabd6319b979927208117a41192637","relation":"main_file"},{"checksum":"3a59759ceeacdb5b578f3803d5e6769b","relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_name":"IST-2016-59-v2+1_2_1_.pdf","file_id":"5148","creator":"system","date_updated":"2020-07-14T12:46:18Z","date_created":"2018-12-12T10:15:28Z","file_size":477976}],"oa":1,"pubrep_id":"59","language":[{"iso":"eng"}],"citation":{"short":"K.

The explicit treatment of strategies allows us to specify properties of nonzero-sum games in a simple and natural way.

We show that strategy logic is decidable, by constructing tree automata that recognize sets of strategies. While for the general logic, our decision procedure is nonelementary, for the simple fragment that is used above we show that the complexity is polynomial in the size of the game graph and optimal in the size of the formula (ranging from polynomial to 2EXPTIME depending on the form of the formula).","lang":"eng"}],"has_accepted_license":"1","publication_status":"published","file_date_updated":"2020-07-14T12:46:18Z","month":"06","file":[{"checksum":"13bff93f3c2a014e2908145a4517f177","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"IST-2012-56-v1+1_Strategy_logic.pdf","file_id":"4911","creator":"system","date_updated":"2020-07-14T12:46:18Z","date_created":"2018-12-12T10:11:54Z","file_size":189120}],"department":[{"_id":"KrCh"},{"_id":"ToHe"}],"pubrep_id":"56","language":[{"iso":"eng"}],"oa":1,"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","issue":"6","citation":{"ista":"Chatterjee K, Henzinger TA, Piterman N. 2010.

As the decidability of the language-inclusion problem remains open for some classes of weighted automata, we introduce a notion of quantitative simulation that is decidable and implies language inclusion.

To solve such games, i.e., to determine the winning regions of players and corresponding winning strategies, one can use the subset construction to build an equivalent perfect-information game. Recently, an algorithm that avoids the inefficient subset construction has been proposed. The algorithm performs a fixed-point computation in a lattice of antichains, thus maintaining a succinct representation of state sets. However, this representation does not allow to recover winning strategies. In this paper, we build on the antichain approach to develop an algorithm for constructing the winning strategies in parity games of imperfect information. One major obstacle in adapting the classical procedure is that the complementation of attractor sets would break the invariant of downward-closedness on which the antichain representation relies. We overcome this difficulty by decomposing problem instances recursively into games with a combination of reachability, safety, and simpler parity conditions. We also report on an experimental implementation of our algorithm: to our knowledge, this is the first implementation of a procedure for solving imperfect-information parity games on graphs."}],"has_accepted_license":"1","publist_id":"2319","related_material":{"record":[{"id":"3880","status":"public","relation":"earlier_version"}]},"year":"2010","date_published":"2010-10-01T00:00:00Z","ec_funded":1,"project":[{"name":"COMponent-Based Embedded Systems design Techniques","grant_number":"215543","call_identifier":"FP7","_id":"25EFB36C-B435-11E9-9278-68D0E5697425"}],"status":"public","publication":"Information and Computation","type":"journal_article","date_updated":"2023-02-23T11:46:47Z","_id":"3863","publisher":"Elsevier","doi":"10.1016/j.ic.2009.09.006","quality_controlled":"1","ddc":["005"],"page":"1206 - 1220"},{"abstract":[{"lang":"eng","text":"Often one has a preference order among the different systems that satisfy a given specification. Under a probabilistic assumption about the possible inputs, such a preference order is naturally expressed by a weighted automaton, which assigns to each word a value, such that a system is preferred if it generates a higher expected value. We solve the following optimal-synthesis problem: given an omega-regular specification, a Markov chain that describes the distribution of inputs, and a weighted automaton that measures how well a system satisfies the given specification tinder the given input assumption, synthesize a system that optimizes the measured value. For safety specifications and measures that are defined by mean-payoff automata, the optimal-synthesis problem amounts to finding a strategy in a Markov decision process (MDP) that is optimal for a long-run average reward objective, which can be done in polynomial time. For general omega-regular specifications, the solution rests on a new, polynomial-time algorithm for computing optimal strategies in MDPs with mean-payoff parity objectives. We present some experimental results showing optimal systems that were automatically generated in this way."}],"intvolume":"      6174","publication_status":"published","oa_version":"Preprint","title":"Measuring and synthesizing systems in probabilistic environments","author":[{"last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","orcid":"0000-0002-4561-241X"},{"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":"Barbara","last_name":"Jobstmann","full_name":"Jobstmann, Barbara"},{"first_name":"Rohit","full_name":"Singh, Rohit","last_name":"Singh"}],"scopus_import":1,"day":"09","date_created":"2018-12-11T12:05:35Z","volume":6174,"language":[{"iso":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ieee":"K.

DIRECT maintains an abstract global state that combines information from every thread, including the sequence of function calls and concurrency primitives executed. The runtime manager can insert delays, provoking thread inter-leavings that may exhibit bugs that are difficult to reach otherwise.

In the case of infinite words, the value of a run is naturally computed as the maximum, limsup, liminf, limit-average, or discounted-sum of the transition weights. The value of a word w is the supremum of the values of the runs over w. We study expressiveness and closure questions about these quantitative languages. We first show that the set of words with value greater than a threshold can be omega-regular for deterministic limit-average and discounted-sum automata, while this set is always omega-regular when the threshold is isolated (i.e., some neighborhood around the threshold contains no word). In the latter case, we prove that the omega-regular language is robust against small perturbations of the transition weights. We next consider automata with transition weights 0 or 1 and show that they are as expressive as general weighted automata in the limit-average case, but not in the discounted-sum case. Third, for quantitative languages L-1 and L-2, we consider the operations max(L-1, L-2), min(L-1, L-2), and 1 - L-1, which generalize the boolean operations on languages, as well as the sum L-1 + L-2. We establish the closure properties of all classes of quantitative languages with respect to these four operations.","lang":"eng"}],"has_accepted_license":"1","date_created":"2018-12-11T12:05:36Z","volume":6,"oa_version":"Published Version","title":"Expressiveness and closure properties for quantitative languages","author":[{"first_name":"Krishnendu","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee"},{"first_name":"Laurent","full_name":"Doyen, Laurent","last_name":"Doyen"},{"last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","first_name":"Thomas A"}],"scopus_import":1,"day":"30","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","issue":"3","citation":{"ista":"Chatterjee K, Doyen L, Henzinger TA. 2010.

We first show that the metrics provide a bound for the difference in long-run average and discounted average behavior across states, indicating that the metrics can be used both in system verification, and in performance evaluation. For turn-based games and MDPs, we provide a polynomial-time algorithm for the computation of the one-step metric distance between states. The algorithm is based on linear programming; it improves on the previous known exponential-time algorithm based on a reduction to the theory of reals. We then present PSPACE algorithms for both the decision problem and the problem of approximating the metric distance between two states, matching the best known algorithms for Markov chains. For the bisimulation kernel of the metric our algorithm works in time O(n(4)) for both turn-based games and MDPs; improving the previously best known O(n(9).log(n)) time algorithm for MDPs. For a concurrent game G, we show that computing the exact distance be tween states is at least as hard as computing the value of concurrent reachability games and the square-root-sum problem in computational geometry. We show that checking whether the metric distance is bounded by a rational r, can be done via a reduction to the theory of real closed fields, involving a formula with three quantifier alternations, yielding O(vertical bar G vertical bar(O(vertical bar G vertical bar 5))) time complexity, improving the previously known reduction, which yielded O(vertical bar G vertical bar(O(vertical bar G vertical bar 7))) time complexity.

While previous work has shown that disease susceptibility at the individual and group level is influenced by gen- etic diversity within and between group members, it remains poorly understood how group-level resistance to pathogens relates directly to individual physiology, defence behaviour and social interactions. We investigated the effects of high versus low genetic diversity on both the individual and collective disease defences in the ant Cardiocondyla obscurior. We compared the antiseptic behaviours (grooming and hygienic behaviour) of workers from genetically homogeneous and diverse colonies after exposure of their brood to the entomopathogenic fungus Metarhizium anisopliae. While workers from diverse colonies performed intensive allogrooming and quickly removed larvae covered with live fungal spores from the nest, workers from homogeneous colonies only removed sick larvae late after infection. This difference was not caused by a reduced repertoire of antiseptic behaviours or a generally decreased brood care activity in ants from homogeneous colonies. Our data instead suggest that reduced genetic diversity compromises the ability of Cardiocondyla colonies to quickly detect or react to the presence of pathogenic fungal spores before an infection is established, thereby affecting the dynamics of social immunity in the colony."}],"intvolume":"       277","main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2981995/"}],"publication_status":"published","day":"05","author":[{"orcid":"0000-0003-1832-8883","first_name":"Line V","last_name":"Ugelvig","full_name":"Ugelvig, Line V","id":"3DC97C8E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Daniel","full_name":"Kronauer, Daniel","last_name":"Kronauer"},{"first_name":"Alexandra","last_name":"Schrempf","full_name":"Schrempf, Alexandra"},{"full_name":"Heinze, Jürgen","last_name":"Heinze","first_name":"Jürgen"},{"id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","full_name":"Cremer, Sylvia","last_name":"Cremer","orcid":"0000-0002-2193-3868","first_name":"Sylvia"}],"doi":"10.1098/rspb.2010.0644","title":"Rapid anti-pathogen response in ant societies relies on high genetic diversity","publisher":"Royal Society, The","oa_version":"None","_id":"3904","volume":277,"date_updated":"2021-01-12T07:53:05Z","date_created":"2018-12-11T12:05:48Z","type":"journal_article","oa":1,"language":[{"iso":"eng"}],"extern":"1","status":"public","publication":"Proceedings of the Royal Society of London Series B Biological Sciences","citation":{"ama":"Ugelvig LV, Kronauer D, Schrempf A, Heinze J, Cremer S.

These chains interact to form collagen types I, III and V, which are fibrillar collagens. Biglycan and decorin, which can decorate fibrillar collagens, were also induced strongly. The fibrillar collagens, biglycan and decorin were largely found between the endothelium and astrocytic glia limitans in the perivascular space where they formed a meshwork which was closely associated with infiltrating immune cells. In active lesions collagen V was also seen in the heavily infiltrated parenchyma. Fibrillar collagens I and III inhibited in vitro human monocyte production of CCL2 (MCP-1), an inflammatory chemokine involved in recruitment of immune cells. Together, ECM changes in lesions with different activities were quantified and proteins forming a perivascular fibrosis were identified.

Analyzing dendritic cell (DC) migration, we showed that these distinct cellular responses depended on the mode of chemokine presentation within tissues. The surface-immobilized form of the chemokine CCL21, the heparan sulfate-anchoring ligand of the CC-chemokine receptor 7 (CCR7), caused random movement of DCs that was confined to the chemokine-presenting surface because it triggered integrin-mediated adhesion. Upon direct contact with CCL21, DCs truncated the anchoring residues of CCL21, thereby releasing it from the solid phase. Soluble CCL21 functionally resembles the second CCR7 ligand, CCL19, which lacks anchoring residues and forms soluble gradients. Both soluble CCR7 ligands triggered chemotactic movement, but not surface adhesion. Adhesive random migration and directional steering cooperate to produce dynamic but spatially restricted locomotion patterns closely resembling the cellular dynamics observed in secondary lymphoid organs."}],"publication_status":"published","doi":"10.1016/j.immuni.2010.04.017","author":[{"first_name":"Kathrin","last_name":"Schumann","full_name":"Schumann, Kathrin","id":"F44D762E-4F9D-11E9-B64C-9EB26CEFFB5F"},{"last_name":"Lämmermann","full_name":"Lämmermann, Tim","first_name":"Tim"},{"first_name":"Markus","last_name":"Bruckner","full_name":"Bruckner, Markus"},{"last_name":"Legler","full_name":"Legler, Daniel","first_name":"Daniel"},{"first_name":"Julien","full_name":"Polleux, Julien","last_name":"Polleux"},{"first_name":"Joachim","last_name":"Spatz","full_name":"Spatz, Joachim"},{"first_name":"Gerold","full_name":"Schuler, Gerold","last_name":"Schuler"},{"first_name":"Reinhold","full_name":"Förster, Reinhold","last_name":"Förster"},{"first_name":"Manfred","last_name":"Lutz","full_name":"Lutz, Manfred"},{"first_name":"Lydia","full_name":"Sorokin, Lydia","last_name":"Sorokin"},{"first_name":"Michael K","orcid":"0000-0002-6620-9179","last_name":"Sixt","full_name":"Sixt, Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"}],"day":"28","title":"Immobilized chemokine fields and soluble chemokine gradients cooperatively shape migration patterns of dendritic cells","oa_version":"None","publisher":"Cell Press","date_updated":"2021-01-12T07:53:29Z","volume":32,"_id":"3959","type":"journal_article","date_created":"2018-12-11T12:06:07Z"},{"main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/issues/190105/"}],"publication_status":"published","quality_controlled":0,"page":"2861 - 2863","intvolume":"        29","abstract":[{"lang":"eng","text":"When lymphocytes follow chemotactic cues, they can adopt different migratory modes depending on the geometry and molecular composition of their extracellular environment.

Accordingly, most leukocytes can efficiently infiltrate and traverse almost every physiological or artificial environment. Here, we review how leukocytes might achieve this task mechanistically, and summarize recent findings on the principles of cytoskeletal force generation and transduction at the leading edge of leukocytes. We propose a model in which the cells switch between adhesion-receptor-mediated force transmission and locomotion modes that are based on cellular deformations, but independent of adhesion receptors. This plasticity in migration strategies allows leukocytes to adapt to the geometry and molecular composition of their environment."}],"quality_controlled":0,"publication_status":"published"}]
