[{"abstract":[{"text":"We present ABC, a software tool for automatically computing symbolic upper bounds on the number of iterations of nested program loops. The system combines static analysis of programs with symbolic summation techniques to derive loop invariant relations between program variables. Iteration bounds are obtained from the inferred invariants, by replacing variables with bounds on their greatest values. We have successfully applied ABC to a large number of examples. The derived symbolic bounds express non-trivial polynomial relations over loop variables. We also report on results to automatically infer symbolic expressions over harmonic numbers as upper bounds on loop iteration counts.","lang":"eng"}],"type":"conference","oa_version":"Submitted Version","status":"public","author":[{"first_name":"Régis","last_name":"Blanc","full_name":"Blanc, Régis"},{"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":"Hottelier, Thibaud","last_name":"Hottelier","first_name":"Thibaud"},{"full_name":"Kovács, Laura","first_name":"Laura","last_name":"Kovács"}],"date_created":"2022-03-21T08:14:35Z","_id":"10908","title":"ABC: Algebraic Bound Computation for loops","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_updated":"2025-09-30T09:51:13Z","page":"103-118","citation":{"ama":"Blanc R, Henzinger TA, Hottelier T, Kovács L.

Second, we prove that for homology of dimension two or higher, the problem is NP-hard to approximate even when the Betti number is O(1). A side effect is the inapproximability of the problem of computing the nonbounding cycle with the smallest volume, and computing cycles representing a homology basis with the minimal total volume.

Methods and programs abound that use the gene alignment in different ways to reconstruct the species tree. In particular, different methods combine the original data at different points along the way from the underlying sequences to the final tree. Accordingly, they are classified into superalignment, supertree and medium-level approaches. Here, we present a simulation study to compare different methods from each of these three approaches.\r\n\r\nResults: We observe that superalignment methods usually outperform the other approaches over a wide range of parameters including sparse data and gene-specific evolutionary parameters. In the presence of high incongruency among gene trees, however, other combination methods show better performance than the superalignment approach. Surprisingly, some supertree and medium-level methods exhibit, on average, worse results than a single gene phylogeny with complete taxon information.\r\n\r\nConclusions: For some methods, using the reconstructed gene tree as an estimation of the species tree is superior to the combination of incomplete information. Superalignment usually performs best since it is less susceptible to stochastic error. Supertree methods can outperform superalignment in the presence of gene-tree conflict."}],"oa_version":"Published Version","type":"journal_article","citation":{"chicago":"Kupczok, Anne, Heiko Schmidt, and Arndt Von Haeseler. “Accuracy of Phylogeny Reconstruction Methods Combining Overlapping Gene Data Sets.” <i>Algorithms for Molecular Biology</i>.

Several correctness properties have been proposed for STMs. Based on a bounded conflict graph algorithm for verifying correctness of STMs, we develop TRACER, a tool for runtime verification of STM implementations. The novelty of TRACER lies in the way it combines coarse and precise runtime analyses to guarantee sound and complete verification in an efficient manner. We implement TRACER in the TL2 STM implementation. We evaluate the performance of TRACER on STAMP benchmarks. While a precise runtime verification technique based on conflict graphs results in an average slowdown of 60x, the two-level approach of TRACER performs complete verification with an average slowdown of around 25x across different benchmarks."}],"_id":"4362","title":"Runtime verification for software transactional memories","status":"public","date_created":"2018-12-11T12:08:28Z","author":[{"full_name":"Singh, Vasu","id":"4DAE2708-F248-11E8-B48F-1D18A9856A87","last_name":"Singh","first_name":"Vasu"}],"volume":6418,"doi":"10.1007/978-3-642-16612-9_32","month":"01","department":[{"_id":"ToHe"}],"publisher":"Springer","day":"01","corr_author":"1","fulldoi":"https://doi.org/10.1007/978-3-642-16612-9_32","date_published":"2010-01-01T00:00:00Z","alternative_title":["LNCS"],"conference":{"location":"St. Julians, Malta","end_date":"2010-11-04","start_date":"2010-11-01","name":"RV: International Conference on Runtime Verification"},"year":"2010","quality_controlled":"1","publication_status":"published","intvolume":"      6418","editor":[{"first_name":"Oleg","last_name":"Sokolsky","full_name":"Sokolsky, Oleg"},{"last_name":"Rosu","first_name":"Grigore","full_name":"Rosu, Grigore"},{"full_name":"Tilmann, Nikolai","first_name":"Nikolai","last_name":"Tilmann"},{"full_name":"Barringer, Howard","last_name":"Barringer","first_name":"Howard"},{"last_name":"Falcone","first_name":"Ylies","full_name":"Falcone, Ylies"},{"full_name":"Finkbeiner, Bernd","last_name":"Finkbeiner","first_name":"Bernd"},{"first_name":"Klaus","last_name":"Havelund","full_name":"Havelund, Klaus"},{"full_name":"Lee, Insup","last_name":"Lee","first_name":"Insup"},{"full_name":"Pace, Gordon","last_name":"Pace","first_name":"Gordon"}]},{"fulldoi":"https://doi.org/10.1007/978-3-642-15297-9_13","has_accepted_license":"1","conference":{"end_date":"2010-09-10","start_date":"2010-09-08","name":"FORMATS: Formal Modeling and Analysis of Timed Systems","location":"Klosterneuburg, Austria"},"date_published":"2010-09-08T00:00:00Z","alternative_title":["LNCS"],"file_date_updated":"2020-07-14T12:46:27Z","intvolume":"      6246","publication_status":"published","quality_controlled":"1","year":"2010","ddc":["004"],"editor":[{"full_name":"Henzinger, Thomas A.","last_name":"Henzinger","first_name":"Thomas A."},{"full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu"}],"doi":"10.1007/978-3-642-15297-9_13","file":[{"content_type":"application/pdf","date_updated":"2020-07-14T12:46:27Z","file_name":"IST-2012-49-v1+1_From_MTL_to_deterministic_timed_automata.pdf","file_size":249789,"file_id":"5028","access_level":"open_access","creator":"system","relation":"main_file","checksum":"b0ca5f5fbe8a3d20ccbc6f51a344a459","date_created":"2018-12-12T10:13:43Z"}],"volume":6246,"publisher":"Springer","department":[{"_id":"ToHe"}],"month":"09","oa":1,"corr_author":"1","pubrep_id":"49","day":"08","date_updated":"2024-10-09T20:54:01Z","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Nickovic, Dejan, and Nir Piterman. “From MTL to Deterministic Timed Automata.” edited by Thomas A.

We handle full mtl and include all future operators. Our construction is based on separation of the continuous time monitoring of the input sequence and discrete predictions regarding the future. The separation of the continuous from the discrete allows us to determinize our automata in an exponential construction that does not increase the number of clocks. This leads to a doubly exponential construction from mtl to deterministic timed automata, compared with triply exponential using existing approaches. We offer an alternative to the existing approach to linear real-time model checking, which has never been implemented. It further offers a unified framework for model checking, runtime monitoring, and synthesis, in an approach that can reuse tools, implementations, and insights from the discrete setting.","lang":"eng"}],"oa_version":"Submitted Version","type":"conference","author":[{"full_name":"Nickovic, Dejan","id":"41BCEE5C-F248-11E8-B48F-1D18A9856A87","first_name":"Dejan","last_name":"Nickovic"},{"first_name":"Nir","last_name":"Piterman","full_name":"Piterman, Nir"}],"status":"public","date_created":"2018-12-11T12:08:30Z","title":"From MTL to deterministic timed automata","_id":"4369","publist_id":"1090","language":[{"iso":"eng"}],"ec_funded":1,"scopus_import":1},{"month":"01","department":[{"_id":"ToHe"}],"publisher":"Springer","day":"01","oa":1,"volume":5944,"doi":"10.1007/978-3-642-11319-2_6","quality_controlled":"1","year":"2010","publication_status":"published","intvolume":"      5944","editor":[{"last_name":"Barthe","first_name":"Gilles","full_name":"Barthe, Gilles"},{"first_name":"Manuel","last_name":"Hermenegildo","full_name":"Hermenegildo, Manuel"}],"fulldoi":"https://doi.org/10.1007/978-3-642-11319-2_6","main_file_link":[{"url":"https://infoscience.epfl.ch/record/161290/","open_access":"1"}],"date_published":"2010-01-01T00:00:00Z","alternative_title":["LNCS"],"conference":{"start_date":"2010-01-17","end_date":"2010-01-19","name":"VMCAI: Verification, Model Checking and Abstract Interpretation","location":"Madrid, Spain"},"scopus_import":1,"publist_id":"1081","language":[{"iso":"eng"}],"type":"conference","oa_version":"Submitted Version","abstract":[{"text":"Techniques such as verification condition generation, predicate abstraction, and expressive type systems reduce software verification to proving formulas in expressive logics. Programs and their specifications often make use of data structures such as sets, multisets, algebraic data types, or graphs. Consequently, formulas generated from verification also involve such data structures. To automate the proofs of such formulas we propose a logic (a “calculus”) of such data structures. We build the calculus by starting from decidable logics of individual data structures, and connecting them through functions and sets, in ways that go beyond the frameworks such as Nelson-Oppen. The result are new decidable logics that can simultaneously specify properties of different kinds of data structures and overcome the limitations of the individual logics. Several of our decidable logics include abstraction functions that map a data structure into its more abstract view (a tree into a multiset, a multiset into a set), into a numerical quantity (the size or the height), or into the truth value of a candidate data structure invariant (sortedness, or the heap property). For algebraic data types, we identify an asymptotic many-to-one condition on the abstraction function that guarantees the existence of a decision procedure. In addition to the combination based on abstraction functions, we can combine multiple data structure theories if they all reduce to the same data structure logic. As an instance of this approach, we describe a decidable logic whose formulas are propositional combinations of formulas in: weak monadic second-order logic of two successors, two-variable logic with counting, multiset algebra with Presburger arithmetic, the Bernays-Schönfinkel-Ramsey class of first-order logic, and the logic of algebraic data types with the set content function. The subformulas in this combination can share common variables that refer to sets of objects along with the common set algebra operations. Such sound and complete combination is possible because the relations on sets definable in the component logics are all expressible in Boolean Algebra with Presburger Arithmetic. Presburger arithmetic and its new extensions play an important role in our decidability results. In several cases, when we combine logics that belong to NP, we can prove the satisfiability for the combined logic is still in NP.","lang":"eng"}],"_id":"4378","title":"Building a calculus of data structures","author":[{"last_name":"Kuncak","first_name":"Viktor","full_name":"Kuncak, Viktor"},{"last_name":"Piskac","first_name":"Ruzica","full_name":"Piskac, Ruzica"},{"full_name":"Suter, Philippe","last_name":"Suter","first_name":"Philippe"},{"last_name":"Wies","first_name":"Thomas","id":"447BFB88-F248-11E8-B48F-1D18A9856A87","full_name":"Wies, Thomas"}],"status":"public","date_created":"2018-12-11T12:08:33Z","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","date_updated":"2021-01-12T07:56:31Z","page":"26 - 44","citation":{"chicago":"Kuncak, Viktor, Ruzica Piskac, Philippe Suter, and Thomas Wies. “Building a Calculus of Data Structures.” edited by Gilles Barthe and Manuel Hermenegildo, 5944:26–44.

We claim that, in order to realize the full potential of cloud computing, the user must be presented with a pricing model that offers flexibility at the requirements level, such as a choice between different degrees of execution speed and the cloud provider must be presented with a programming model that offers flexibility at the execution level, such as a choice between different scheduling policies. In such a flexible framework, with each job, the user purchases a virtual computer with the desired speed and cost characteristics, and the cloud provider can optimize the utilization of resources across a stream of jobs from different users. We designed a flexible framework to test our hypothesis, which is called FlexPRICE (Flexible Provisioning of Resources in a Cloud Environment) and works as follows. A user presents a job to the cloud. The cloud finds different schedules to execute the job and presents a set of quotes to the user in terms of price and duration for the execution. The user then chooses a particular quote and the cloud is obliged to execute the job according to the chosen quote. FlexPRICE thus hides the complexity of the actual scheduling decisions from the user, but still provides enough flexibility to meet the users actual demands. We implemented FlexPRICE in a simulator called PRICES that allows us to experiment with our framework. We observe that FlexPRICE provides a wide range of execution options-from fast and expensive to slow and cheap-- for the whole spectrum of data-intensive and computation-intensive jobs. We also observe that the set of quotes computed by FlexPRICE do not vary as the number of simultaneous jobs increases."}],"type":"conference","oa_version":"Submitted Version","publist_id":"1077","language":[{"iso":"eng"}],"scopus_import":1,"article_processing_charge":"No","has_accepted_license":"1","conference":{"end_date":"2010-07-10","start_date":"2010-07-05","name":"CLOUD: Cloud Computing","location":"Miami, USA"},"file_date_updated":"2020-07-14T12:46:28Z","date_published":"2010-08-26T00:00:00Z","fulldoi":"https://doi.org/10.1109/CLOUD.2010.71","ddc":["004"],"publication_status":"published","year":"2010","quality_controlled":"1","doi":"10.1109/CLOUD.2010.71","file":[{"file_size":467436,"date_updated":"2020-07-14T12:46:28Z","content_type":"application/pdf","file_name":"IST-2012-47-v1+1_FlexPRICE-_Flexible_provisioning_of_resources_in_a_cloud_environment.pdf","file_id":"5188","creator":"system","relation":"main_file","access_level":"open_access","checksum":"98e534675339a8e2beca08890d048145","date_created":"2018-12-12T10:16:03Z"}],"oa":1,"corr_author":"1","pubrep_id":"47","day":"26","publisher":"IEEE","department":[{"_id":"ToHe"}],"month":"08"},{"year":"2010","quality_controlled":"1","publication_status":"published","ddc":["005"],"fulldoi":"https://doi.org/10.1145/1810479.1810529","file_date_updated":"2020-07-14T12:46:28Z","date_published":"2010-06-13T00:00:00Z","has_accepted_license":"1","conference":{"location":"Santorini, Greece","name":"SPAA: ACM Symposium on Parallel Algorithms and Architectures","end_date":"2010-06-15","start_date":"2010-06-13"},"department":[{"_id":"ToHe"}],"month":"06","publisher":"ACM","pubrep_id":"46","oa":1,"day":"13","file":[{"date_created":"2018-12-12T10:14:28Z","checksum":"f2ad6c00a6304da34bf21bcdcfd36c4b","creator":"system","relation":"main_file","access_level":"open_access","file_id":"5080","file_size":246409,"file_name":"IST-2012-46-v1+1_Transactions_in_the_jungle.pdf","date_updated":"2020-07-14T12:46:28Z","content_type":"application/pdf"}],"doi":"10.1145/1810479.1810529","abstract":[{"text":"Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. Inspired by classical work on databases, formal definitions of the semantics of TM executions have been proposed. Many of these definitions assumed that accesses to shared data are solely performed through transactions. In practice, due to legacy code and concurrency libraries, transactions in a TM have to share data with non-transactional operations. The semantics of such interaction, while widely discussed by practitioners, lacks a clear formal specification. Those interactions can vary, sometimes in subtle ways, between TM implementations and underlying memory models. We propose a correctness condition for TMs, parametrized opacity, to formally capture the now folklore notion of strong atomicity by stipulating the two following intuitive requirements: first, every transaction appears as if it is executed instantaneously with respect to other transactions and non-transactional operations, and second, non-transactional operations conform to the given underlying memory model. We investigate the inherent cost of implementing parametrized opacity. We first prove that parametrized opacity requires either instrumenting non-transactional operations (for most memory models) or writing to memory by transactions using potentially expensive read-modify-write instructions (such as compare-and-swap). Then, we show that for a class of practical relaxed memory models, parametrized opacity can indeed be implemented with constant-time instrumentation of non-transactional writes and no instrumentation of non-transactional reads. We show that, in practice, parametrizing the notion of correctness allows developing more efficient TM implementations.","lang":"eng"}],"oa_version":"Submitted Version","type":"conference","date_created":"2018-12-11T12:08:34Z","author":[{"full_name":"Guerraoui, Rachid","last_name":"Guerraoui","first_name":"Rachid"},{"first_name":"Thomas A","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724"},{"first_name":"Michal","last_name":"Kapalka","full_name":"Kapalka, Michal"},{"id":"4DAE2708-F248-11E8-B48F-1D18A9856A87","last_name":"Singh","first_name":"Vasu","full_name":"Singh, Vasu"}],"status":"public","_id":"4382","title":"Transactions in the jungle","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","date_updated":"2024-10-21T06:03:05Z","citation":{"apa":"Guerraoui, R., Henzinger, T.

These components are interconnected with other, possibly analog, devices and the physical environment. This environment cannot be entirely captured and can provide inaccurate input data to the component. It is thus important for digital components to have a robust behavior, i.e. the presence of a small change in the input sequences should not result in a drastic change in the output sequences. In this paper, we study a notion of robustness for sequential circuits. However, since sequential circuits may have parts that are naturally discontinuous (e.g., digital controllers with switching behavior), we need a flexible framework that accommodates this fact and leaves discontinuous parts of the circuit out from the robustness analysis. As a consequence, we consider sequential circuits that have their input variables partitioned into two disjoint sets: control and disturbance variables. Our contributions are (1) a definition of robustness for sequential circuits as a form of continuity with respect to disturbance variables, (2) the characterization of the exact class of sequential circuits that are robust according to our definition, (3) an algorithm to decide whether a sequential circuit is robust or not.","lang":"eng"}],"page":"77 - 84","citation":{"ama":"Doyen L, Henzinger TA, Legay A, Nickovic D.

The difficulty of reasoning about these implementations does not stem from the number of variables or the program size, but rather from the large number of possible interleavings. These implementations are therefore prime candidates for model checking. We introduce an algorithm for verifying linearizability of singly-linked heap-based concurrent data structures. We consider a model consisting of an unbounded heap where each vertex stores an element from an unbounded data domain, with a restricted set of operations for testing and updating pointers and data elements. Our main result is that linearizability is decidable for programs that invoke a fixed number of methods, possibly in parallel. This decidable fragment covers many of the common implementation techniques — fine-grained locking, lazy synchronization, and lock-free synchronization. We also show how the technique can be used to verify optimistic implementations with the help of programmer annotations. We developed a verification tool CoLT and evaluated it on a representative sample of Java implementations of the concurrent set data structure. The tool verified linearizability of a number of implementations, found a known error in a lock-free implementation and proved that the corrected version is linearizable.","lang":"eng"}],"oa_version":"Submitted Version","type":"conference","date_created":"2018-12-11T12:08:36Z","author":[{"full_name":"Cerny, Pavol","first_name":"Pavol","last_name":"Cerny","id":"4DCBEFFE-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Arjun","last_name":"Radhakrishna","id":"3B51CAC4-F248-11E8-B48F-1D18A9856A87","full_name":"Radhakrishna, Arjun"},{"id":"4397AC76-F248-11E8-B48F-1D18A9856A87","last_name":"Zufferey","first_name":"Damien","orcid":"0000-0002-3197-8736","full_name":"Zufferey, Damien"},{"first_name":"Swarat","last_name":"Chaudhuri","full_name":"Chaudhuri, Swarat"},{"full_name":"Alur, Rajeev","last_name":"Alur","first_name":"Rajeev"}],"status":"public","_id":"4390","title":"Model checking of linearizability of concurrent list implementations","file":[{"date_created":"2020-05-19T16:31:56Z","checksum":"2eb211ce40b3c4988bce3a3592980704","relation":"main_file","creator":"dernst","access_level":"open_access","file_id":"7873","file_size":3633276,"file_name":"2010_CAV_Cerny.pdf","date_updated":"2020-07-14T12:46:28Z","content_type":"application/pdf"}],"doi":"10.1007/978-3-642-14295-6_41","volume":6174,"department":[{"_id":"ToHe"}],"month":"07","publisher":"Springer","pubrep_id":"27","oa":1,"corr_author":"1","day":"01","fulldoi":"https://doi.org/10.1007/978-3-642-14295-6_41","article_processing_charge":"No","alternative_title":["LNCS"],"file_date_updated":"2020-07-14T12:46:28Z","date_published":"2010-07-01T00:00:00Z","has_accepted_license":"1","conference":{"end_date":"2010-07-17","start_date":"2010-07-15","name":"CAV: Computer Aided Verification","location":"Edinburgh, UK"},"intvolume":"      6174","quality_controlled":"1","year":"2010","publication_status":"published","ddc":["000"]},{"citation":{"ama":"Cerny P, Henzinger TA, Radhakrishna A.

Quantitative measures of correctness can be formalized by real-valued distance functions between systems, where the distance between implementation and specification provides a measure of “fit” or “desirability.” We extend the simulation preorder to the quantitative setting, by making each player of a simulation game pay a certain price for her choices. We use the resulting games with quantitative objectives to define three different simulation distances. The correctness distance measures how much the specification must be changed in order to be satisfied by the implementation. The coverage distance measures how much the implementation restricts the degrees of freedom offered by the specification. The robustness distance measures how much a system can deviate from the implementation description without violating the specification. We consider these distances for safety as well as liveness specifications. The distances can be computed in polynomial time for safety specifications, and for liveness specifications given by weak fairness constraints. We show that the distance functions satisfy the triangle inequality, that the distance between two systems does not increase under parallel composition with a third system, and that the distance between two systems can be bounded from above and below by distances between abstractions of the two systems. These properties suggest that our simulation distances provide an appropriate basis for a quantitative theory of discrete systems. We also demonstrate how the robustness distance can be used to measure how many transmission errors are tolerated by error correcting codes.","lang":"eng"}],"_id":"4393","title":"Simulation distances","date_created":"2018-12-11T12:08:37Z","status":"public","author":[{"first_name":"Pavol","last_name":"Cerny","id":"4DCBEFFE-F248-11E8-B48F-1D18A9856A87","full_name":"Cerny, Pavol"},{"orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","first_name":"Thomas A","last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Radhakrishna, Arjun","first_name":"Arjun","last_name":"Radhakrishna","id":"3B51CAC4-F248-11E8-B48F-1D18A9856A87"}],"language":[{"iso":"eng"}],"publist_id":"1065","ec_funded":1,"acknowledgement":"This work was partially supported by the European Union project COMBEST and the European Network of Excellence ArtistDesign.","scopus_import":1},{"author":[{"full_name":"Beyer, Dirk","last_name":"Beyer","first_name":"Dirk"},{"full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","first_name":"Thomas A"},{"full_name":"Théoduloz, Grégory","last_name":"Théoduloz","first_name":"Grégory"},{"id":"4397AC76-F248-11E8-B48F-1D18A9856A87","last_name":"Zufferey","first_name":"Damien","orcid":"0000-0002-3197-8736","full_name":"Zufferey, Damien"}],"date_created":"2018-12-11T12:08:38Z","status":"public","_id":"4396","title":"Shape refinement through explicit heap analysis","abstract":[{"text":"Shape analysis is a promising technique to prove program properties about recursive data structures.

The approach uses two techniques to guide the refinement of shape abstractions: (1) during program exploration, an explicit heap analysis collects sample instances of the heap structures, which are used to identify the data structures that are manipulated by the program; and (2) during abstraction refinement along an infeasible error path, we consider different possible heap abstractions and choose the coarsest one that eliminates the infeasible path. We have implemented this combined approach for automatic shape refinement as an extension of the software model checker BLAST.

These are replaced by offspring from a small number of parents, drawn from the preexisting population. This model of evolution forwards in time corresponds to a backwards model, in which ancestral lineages jump to a new location if they are hit by an event, and may coalesce with other lineages that are hit by the same event. We derive an expression for the identity in allelic state, and show that, over scales much larger than the largest event, this converges to the classical value derived by Wright and Malécot.

A streaming string transducer makes a single pass through the input string and uses a finite set of variables that range over strings from the output alphabet. At every step, the transducer processes an input symbol, and updates all the variables in parallel using assignments whose right-hand-sides are concatenations of output symbols and variables with the restriction that a variable can be used at most once in a right-hand-side expression. It has been shown that streaming string transducers operating on strings over infinite data domains are of interest in algorithmic verification of list-processing programs, as they lead to PSPACE decision procedures for checking pre/post conditions and for checking semantic equivalence, for a well-defined class of heap-manipulating programs. In order to understand the theoretical expressiveness of streaming transducers, we focus on streaming transducers processing strings over finite alphabets, given the existence of a robust and well-studied class of &quot;regular&quot; transductions for this case. Such regular transductions can be defined either by two-way deterministic finite-state transducers, or using a logical MSO-based characterization. Our main result is that the expressiveness of streaming string transducers coincides exactly with this class of regular transductions.

The evolution of the system depends on the decisions of both players, supplemented by chance. In this work, we focus on the notion of randomised strategy. More specifically, we show that three natural definitions may lead to very different results: in the most general cases, an almost-surely winning situation may become almost-surely losing if the player is only allowed to use a weaker notion of strategy. In more reasonable settings, translations exist, but they require infinite memory, even in simple cases. Finally, some traditional problems becomes undecidable for the strongest type of strategies."}],"type":"conference","oa_version":"Published Version","status":"public","author":[{"full_name":"Cristau, Julien","first_name":"Julien","last_name":"Cristau"},{"first_name":"Claire","last_name":"David","full_name":"David, Claire"},{"first_name":"Florian","last_name":"Horn","id":"37327ACE-F248-11E8-B48F-1D18A9856A87","full_name":"Horn, Florian"}],"date_created":"2018-12-11T11:46:45Z","_id":"489","title":"How do we remember the past in randomised strategies?","language":[{"iso":"eng"}],"publist_id":"7332","scopus_import":"1","publication":"Proceedings of GandALF 2010","arxiv":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1006.1404"}],"fulldoi":"https://doi.org/10.4204/EPTCS.25.7","article_processing_charge":"No","alternative_title":["EPTCS"],"date_published":"2010-06-09T00:00:00Z","conference":{"location":"Minori, Amalfi Coast, Italy","start_date":"2010-06-17","end_date":"2010-06-18","name":"GandALF: Games, Automata, Logic, and Formal Verification"},"intvolume":"        25","year":"2010","quality_controlled":"1","publication_status":"published","ddc":["000"],"doi":"10.4204/EPTCS.25.7","volume":25,"month":"06","department":[{"_id":"KrCh"}],"publisher":"Open Publishing Association","external_id":{"arxiv":["1006.1404"]},"corr_author":"1","oa":1,"day":"09"}]
