We consider a generalised version of discounted reward objectives, in which the amount of discounting depends on the states visited and on the objective. This definition extends the usual definition of discounted reward, and allows to capture the systems in which the value of different commodities diminish at different and variable rates.\r\n\r\nWe establish results for two prominent subclasses of the problem, namely state-discount models where the discount factors are only dependent on the state of the MDP (and independent of the objective), and reward-discount models where they are only dependent on the objective (but not on the state of the MDP). For the state-discount models we use a straightforward reduction to expected total reward and show that the problem whether a value is achievable can be solved in polynomial time. For the reward-discount model we show that memory and randomisation of the strategies are required, but nevertheless that the problem is decidable and it is sufficient to consider strategies which after a certain number of steps behave in a memoryless way.\r\n\r\nFor the general case, we show that when restricted to graphs (i.e. MDPs with no randomisation), pure strategies and discount factors of the form 1/n where n is an integer, the problem is in PSPACE and finite memory suffices for achieving a given value. We also show that when the discount factors are not of the form 1/n, the memory required by a strategy can be infinite.\r\n","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"grant_number":"279307","name":"Quantitative Graph Games: Theory and Applications","_id":"2581B60A-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"doi":"10.1007/978-3-642-45221-5_17","volume":8312,"page":"228 - 242","publisher":"Springer","ec_funded":1,"date_updated":"2020-08-11T10:09:42Z","series_title":"Lecture Notes in Computer Science","day":"01","type":"conference","date_created":"2018-12-11T11:56:30Z","status":"public","date_published":"2013-12-01T00:00:00Z","oa_version":"None","publication_status":"published","year":"2013","citation":{"ista":"Chatterjee K, Forejt V, Wojtczak D. 2013.

We want to &quot;untangle&quot; the βj from the αi by a self-homeomorphism of ℳ; more precisely, we seek an homeomorphism φ: ℳ → ℳ fixing the boundary of ℳ pointwise such that the total number of crossings of the αi with the φ(βj) is as small as possible. This problem is motivated by an application in the algorithmic theory of embeddings and 3-manifolds. We prove that if ℳ is planar, i.e., a sphere with h ≥ 0 boundary components (&quot;holes&quot;), then O(mn) crossings can be achieved (independently of h), which is asymptotically tight, as an easy lower bound shows. In general, for an arbitrary (orientable or nonorientable) surface ℳ with h holes and of (orientable or nonorientable) genus g ≥ 0, we obtain an O((m + n)4) upper bound, again independent of h and g.

Here we study direct reciprocity in the context of the alternating Prisoner's Dilemma. We consider all strategies that can be implemented by one and two-state automata. We calculate the payoff matrix of all pairwise encounters in the presence of noise. We explore deterministic selection dynamics with and without mutation. Using different error rates and payoff values, we observe convergence to a small number of distinct equilibria. Two of them are uncooperative strict Nash equilibria representing always-defect (ALLD) and Grim. The third equilibrium is mixed and represents a cooperative alliance of several strategies, dominated by a strategy which we call Forgiver. Forgiver cooperates whenever the opponent has cooperated; it defects once when the opponent has defected, but subsequently Forgiver attempts to re-establish cooperation even if the opponent has defected again. Forgiver is not an evolutionarily stable strategy, but the alliance, which it rules, is asymptotically stable. For a wide range of parameter values the most commonly observed outcome is convergence to the mixed equilibrium, dominated by Forgiver. Our results show that although forgiving might incur a short-term loss it can lead to a long-term gain. Forgiveness facilitates stable cooperation in the presence of exploitation and noise.","lang":"eng"}],"type":"journal_article","day":"12","date_updated":"2025-09-29T14:30:03Z","status":"public","date_created":"2018-12-11T11:56:33Z","isi":1,"file_date_updated":"2020-07-14T12:45:34Z","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publisher":"Public Library of Science","ec_funded":1,"publication":"PLoS One","related_material":{"record":[{"relation":"research_data","status":"public","id":"9749"},{"relation":"dissertation_contains","status":"public","id":"1400"}]},"month":"12","citation":{"apa":"Zagorsky, B., Reiter, J., Chatterjee, K., &#38; Nowak, M.

The verifier is able to recover m from τ and at the same time verify its authenticity. The two most important parameters of such a scheme are its security and overhead |τ| − |m|. A simple argument shows that for any scheme with “n bits security” |τ| − |m| ≥ n, i.e., the overhead is lower bounded by the security parameter n. Currently, the best known constructions in the random oracle model are far from this lower bound requiring an overhead of n + logq h , where q h is the number of queries to the random oracle. In this paper we give a construction which basically matches the n bit lower bound. We propose a simple digital signature scheme with n + o(logq h ) bits overhead, where q h denotes the number of random oracle queries.\r\n\r\nOur construction works in two steps. First, we propose a signature scheme with message recovery having optimal overhead in a new ideal model, the random invertible function model. Second, we show that a four-round Feistel network with random oracles as round functions is tightly “public-indifferentiable” from a random invertible function. At the core of our indifferentiability proof is an almost tight upper bound for the expected number of edges of the densest “small” subgraph of a random Cayley graph, which may be of independent interest.\r\n","lang":"eng"}],"doi":"10.1007/978-3-642-40041-4_31","pubrep_id":"685","project":[{"grant_number":"259668","name":"Provable Security for Physical Cryptography","_id":"258C570E-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"volume":8042},{"date_created":"2018-12-11T11:56:37Z","status":"public","date_updated":"2021-01-12T06:56:21Z","type":"conference","series_title":"Lecture Notes in Computer Science","day":"01","ec_funded":1,"publisher":"Springer","file_date_updated":"2020-07-14T12:45:35Z","page":"57 - 74","volume":8042,"pubrep_id":"684","project":[{"call_identifier":"FP7","_id":"258C570E-B435-11E9-9278-68D0E5697425","name":"Provable Security for Physical Cryptography","grant_number":"259668"}],"doi":"10.1007/978-3-642-40041-4_4","abstract":[{"lang":"eng","text":"The learning with rounding (LWR) problem, introduced by Banerjee, Peikert and Rosen at EUROCRYPT ’12, is a variant of learning with errors (LWE), where one replaces random errors with deterministic rounding. The LWR problem was shown to be as hard as LWE for a setting of parameters where the modulus and modulus-to-error ratio are super-polynomial. In this work we resolve the main open problem and give a new reduction that works for a larger range of parameters, allowing for a polynomial modulus and modulus-to-error ratio. In particular, a smaller modulus gives us greater efficiency, and a smaller modulus-to-error ratio gives us greater security, which now follows from the worst-case hardness of GapSVP with polynomial (rather than super-polynomial) approximation factors.\r\n\r\nAs a tool in the reduction, we show that there is a “lossy mode” for the LWR problem, in which LWR samples only reveal partial information about the secret. This property gives us several interesting new applications, including a proof that LWR remains secure with weakly random secrets of sufficient min-entropy, and very simple constructions of deterministic encryption, lossy trapdoor functions and reusable extractors.\r\n\r\nOur approach is inspired by a technique of Goldwasser et al. from ICS ’10, which implicitly showed the existence of a “lossy mode” for LWE. By refining this technique, we also improve on the parameters of that work to only requiring a polynomial (instead of super-polynomial) modulus and modulus-to-error ratio.\r\n"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"scopus_import":1,"intvolume":"      8042","alternative_title":["LNCS"],"quality_controlled":"1","title":"Learning with rounding, revisited: New reduction properties and applications","_id":"2259","file":[{"file_name":"IST-2016-684-v1+1_098.pdf","checksum":"16d428408a806b8e49eecc607deab115","content_type":"application/pdf","relation":"main_file","access_level":"open_access","date_updated":"2020-07-14T12:45:35Z","creator":"system","file_id":"4912","date_created":"2018-12-12T10:11:55Z","file_size":587898}],"oa":1,"has_accepted_license":"1","ddc":["000","004"],"publist_id":"4687","conference":{"location":"Santa Barbara, CA, United States","name":"CRYPTO: International Cryptology Conference","end_date":"2013-08-22","start_date":"2013-08-18"},"department":[{"_id":"KrPi"}],"author":[{"first_name":"Joel F","last_name":"Alwen","full_name":"Alwen, Joel F","id":"2A8DFA8C-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Krenn, Stephan","first_name":"Stephan","last_name":"Krenn","id":"329FCCF0-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2835-9093"},{"id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak","first_name":"Krzysztof Z"},{"first_name":"Daniel","last_name":"Wichs","full_name":"Wichs, Daniel"}],"month":"01","issue":"1","citation":{"ista":"Alwen JF, Krenn S, Pietrzak KZ, Wichs D. 2013.

Differential conditional deletion of Sp2 in early embryonic cerebral cortical progenitors, and perinatal olfactory bulb progenitors disrupted transitions through G1, G2 and M phases, whereas DNA synthesis appeared intact. Cell-autonomous function of Sp2 was identified by deletion of Sp2 using mosaic analysis with double markers, which clearly established that conditional Sp2-null NSCs and NPCs are M phase arrested in vivo. Importantly, conditional deletion of Sp2 led to a decline in the generation of NPCs and neurons in the developing and postnatal brains.

A GPU implementation is discussed and performance characteristics of the method are shown and compared to traditional sampling-based rendering methods.","lang":"eng"}],"date_published":"2013-05-06T00:00:00Z","publication_status":"published","year":"2013"},{"article_processing_charge":"No","abstract":[{"lang":"eng","text":"Representation languages for coalitional games are a key research area in algorithmic game theory.   There is an inher-\r\nent tradeoff between how general a language is, allowing it to  capture  more  elaborate  games,  and  how  hard  it  is  computationally to optimize and solve such games.  One prominent  such  language  is  the  simple  yet  expressive\r\nWeighted Graph Games  (WGGs) representation (Deng  and Papadimitriou 1994), which maintains knowledge about synergies between agents in the form of an edge weighted graph. We  consider  the  problem  of  finding  the  optimal  coalition structure in WGGs. The agents in such games are vertices in a graph, and the value of a coalition is the sum of the weights of the edges present between coalition members. The optimal coalition structure is a partition of the agents to coalitions, that maximizes the sum of utilities obtained by the coalitions. We  show  that  finding  the  optimal  coalition  structure  is  not only hard for general graphs,  but is also intractable for restricted families such as planar graphs which are amenable for many other combinatorial problems.  We then provide algorithms with constant factor approximations for planar, minorfree and bounded degree graphs."}],"OA_place":"repository","date_published":"2013-12-31T00:00:00Z","year":"2013","oa_version":"Preprint","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"green","language":[{"iso":"eng"}],"author":[{"full_name":"Bachrach, Yoram","last_name":"Bachrach","first_name":"Yoram"},{"full_name":"Kohli, Pushmeet","first_name":"Pushmeet","last_name":"Kohli"},{"id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","full_name":"Kolmogorov, Vladimir","last_name":"Kolmogorov","first_name":"Vladimir"},{"full_name":"Zadimoghaddam, Morteza","first_name":"Morteza","last_name":"Zadimoghaddam"}],"month":"12","citation":{"ieee":"Y.

In this model the energy of a string (labeling) x1...xn is the sum of terms over intervals [i,j] where each term is non-zero only if the substring xi...xj equals a prespecified pattern α. Such CRFs can be naturally applied to many sequence tagging problems.\r\nWe present efficient algorithms for the three standard inference tasks in a CRF, namely computing (i) the partition function, (ii) marginals, and (iii) computing the MAP. Their complexities are respectively O(nL), O(nLℓmax) and O(nLmin{|D|,log(ℓmax+1)}) where L is the combined length of input patterns, ℓmax is the maximum length of a pattern, and D is the input alphabet. This improves on the previous algorithms of (Ye et al., 2009) whose complexities are respectively O(nL|D|), O(n|Γ|L2ℓ2max) and O(nL|D|), where |Γ| is the number of input patterns.\r\nIn addition, we give an efficient algorithm for sampling. Finally, we consider the case of non-positive weights. (Komodakis &amp; Paragios, 2009) gave an O(nL) algorithm for computing the MAP. We present a modification that has the same worst-case complexity but can beat it in the best case.
