  text: 'In two-player games on graphs, the players move a token through a graph to
    produce an infinite path, which determines the winner of the game. Such games
    are central in formal methods since they model the interaction between a non-terminating
    system and its environment. In bidding games the players bid for the right to
    move the token: in each round, the players simultaneously submit bids, and the
    higher bidder moves the token and pays the other player. Bidding games are known
    to have a clean and elegant mathematical structure that relies on the ability
    of the players to submit arbitrarily small bids. Many applications, however, require
    a fixed granularity for the bids, which can represent, for example, the monetary
    value expressed in cents. We study, for the first time, the combination of discrete-bidding
    and infinite-duration games. Our most important result proves that these games
    form a large determined subclass of concurrent games, where determinacy is the
    strong property that there always exists exactly one player who can guarantee
    winning the game. In particular, we show that, in contrast to non-discrete bidding
    games, the mechanism with which tied bids are resolved plays an important role
    in discrete-bidding games. We study several natural tie-breaking mechanisms and
    show that, while some do not admit determinacy, most natural mechanisms imply
    determinacy for every pair of initial budgets. '

  text: In this paper, we design novel liquid time-constant recurrent neural networks
    for robotic control, inspired by the brain of the nematode, C. elegans. In the
    worm's nervous system, neurons communicate through nonlinear time-varying synaptic
    links established amongst them by their particular wiring structure. This property
    enables neurons to express liquid time-constants dynamics and therefore allows
    the network to originate complex behaviors with a small number of neurons. We
    identify neuron-pair communication motifs as design operators and use them to
    configure compact neuronal network structures to govern sequential robotic tasks.
    The networks are systematically designed to map the environmental observations
    to motor actions, by their hierarchical topology from sensory neurons, through
    recurrently-wired interneurons, to motor neurons. The networks are then parametrized
    in a supervised-learning scheme by a search-based algorithm. We demonstrate that
    obtained networks realize interpretable dynamics. We evaluate their performance
    in controlling mobile and arm robots, and compare their attributes to other artificial
    neural network-based control agents. Finally, we experimentally show their superior
    resilience to environmental noise, compared to the existing machine learning-based
    methods.

  text: "Hybrid automata combine finite automata and dynamical systems, and model
    the interaction of digital with physical systems. Formal analysis that can guarantee
    the safety of all behaviors or rigorously witness failures, while unsolvable in
    general, has been tackled algorithmically using, e.g., abstraction, bounded model-checking,
    assisted theorem proving.\r\nNevertheless, very few methods have addressed the
    time-unbounded reachability analysis of hybrid automata and, for current sound
    and automatic tools, scalability remains critical. We develop methods for the
    polyhedral abstraction of hybrid automata, which construct coarse overapproximations
    and tightens them incrementally, in a CEGAR fashion. We use template polyhedra,
    i.e., polyhedra whose facets are normal to a given set of directions.\r\nWhile,
    previously, directions were given by the user, we introduce (1) the first method\r\nfor
    computing template directions from spurious counterexamples, so as to generalize
    and\r\neliminate them. The method applies naturally to convex hybrid automata,
    i.e., hybrid\r\nautomata with (possibly non-linear) convex constraints on derivatives
    only, while for linear\r\nODE requires further abstraction. Specifically, we introduce
    (2) the conic abstractions,\r\nwhich, partitioning the state space into appropriate
    (possibly non-uniform) cones, divide\r\ncurvy trajectories into relatively straight
    sections, suitable for polyhedral abstractions.\r\nFinally, we introduce (3) space-time
    interpolation, which, combining interval arithmetic\r\nand template refinement,
    computes appropriate (possibly non-uniform) time partitioning\r\nand template
    directions along spurious trajectories, so as to eliminate them.\r\nWe obtain
    sound and automatic methods for the reachability analysis over dense\r\nand unbounded
    time of convex hybrid automata and hybrid automata with linear ODE.\r\nWe build
    prototype tools and compare—favorably—our methods against the respective\r\nstate-of-the-art
    tools, on several benchmarks."

  text: In this paper, we introduce a novel method to interpret recurrent neural networks
    (RNNs), particularly long short-term memory networks (LSTMs) at the cellular level.
    We propose a systematic pipeline for interpreting individual hidden state dynamics
    within the network using response characterization methods. The ranked contribution
    of individual cells to the network's output is computed by analyzing a set of
    interpretable metrics of their decoupled step and sinusoidal responses. As a result,
    our method is able to uniquely identify neurons with insightful dynamics, quantify
    relationships between dynamical properties and test accuracy through ablation
    analysis, and interpret the impact of network capacity on a network's dynamical
    distribution. Finally, we demonstrate the generalizability and scalability of
    our method by evaluating a series of different benchmark sequential datasets.

  text: We show how to construct temporal testers for the logic MITL, a prominent
    linear-time logic for real-time systems. A temporal tester is a transducer that
    inputs a signal holding the Boolean value of atomic propositions and outputs the
    truth value of a formula along time. Here we consider testers over continuous-time
    Boolean signals that use clock variables to enforce duration constraints, as in
    timed automata. We first rewrite the MITL formula into a “simple” formula using
    a limited set of temporal modalities. We then build testers for these specific
    modalities and show how to compose testers for simple formulae into complex ones.
    Temporal testers can be turned into acceptors, yielding a compositional translation
    from MITL to timed automata. This construction is much simpler than previously
    known and remains asymptotically optimal. It supports both past and future operators
    and can easily be extended.

  text: "The expression of a gene is characterised by its transcription factors and
    the function processing them. If the transcription factors are not affected by
    gene products, the regulating function is often represented as a combinational
    logic circuit, where the outputs (product) are determined by current input values
    (transcription factors) only, and are hence independent on their relative arrival
    times. However, the simultaneous arrival of transcription factors (TFs) in genetic
    circuits is a strong assumption, given that the processes of transcription and
    translation of a gene into a protein introduce intrinsic time delays and that
    there is no global synchronisation among the arrival times of different molecular
    species at molecular targets.\r\n\r\nIn this paper, we construct an experimentally
    implementable genetic circuit with two inputs and a single output, such that,
    in presence of small delays in input arrival, the circuit exhibits qualitatively
    distinct observable phenotypes. In particular, these phenotypes are long lived
    transients: they all converge to a single value, but so slowly, that they seem
    stable for an extended time period, longer than typical experiment duration. We
    used rule-based language to prototype our circuit, and we implemented a search
    for finding the parameter combinations raising the phenotypes of interest.\r\n\r\nThe
    behaviour of our prototype circuit has wide implications. First, it suggests that
    GRNs can exploit event timing to create phenotypes. Second, it opens the possibility
    that GRNs are using event timing to react to stimuli and memorise events, without
    explicit feedback in regulation. From the modelling perspective, our prototype
    circuit demonstrates the critical importance of analysing the transient dynamics
    at the promoter binding sites of the DNA, before applying rapid equilibrium assumptions."

  text: 'Cyber-physical systems (CPS) and the Internet-of-Things (IoT) result in a
    tremendous amount of generated, measured and recorded time-series data. Extracting
    temporal segments that encode patterns with useful information out of these huge
    amounts of data is an extremely difficult problem. We propose shape expressions
    as a declarative formalism for specifying, querying and extracting sophisticated
    temporal patterns from possibly noisy data. Shape expressions are regular expressions
    with arbitrary (linear, exponential, sinusoidal, etc.) shapes with parameters
    as atomic predicates and additional constraints on these parameters. We equip
    shape expressions with a novel noisy semantics that combines regular expression
    matching semantics with statistical regression. We characterize essential properties
    of the formalism and propose an efficient approximate shape expression matching
    procedure. We demonstrate the wide applicability of this technique on two case
    studies. '

  text: Piecewise Barrier Tubes (PBT) is a new technique for flowpipe overapproximation
    for nonlinear systems with polynomial dynamics, which leverages a combination
    of barrier certificates. PBT has advantages over traditional time-step based methods
    in dealing with those nonlinear dynamical systems in which there is a large difference
    in speed between trajectories, producing an overapproximation that is time independent.
    However, the existing approach for PBT is not efficient due to the application
    of interval methods for enclosure-box computation, and it can only deal with continuous
    dynamical systems without uncertainty. In this paper, we extend the approach with
    the ability to handle both continuous and hybrid dynamical systems with uncertainty
    that can reside in parameters and/or noise. We also improve the efficiency of
    the method significantly, by avoiding the use of interval-based methods for the
    enclosure-box computation without loosing soundness. We have developed a C++ prototype
    implementing the proposed approach and we evaluate it on several benchmarks. The
    experiments show that our approach is more efficient and precise than other methods
    in the literature.

  text: 'We present Mixed-time Signal Temporal Logic (STL−MX), a specification formalism
    which extends STL by capturing the discrete/ continuous time duality found in
    many cyber-physical systems (CPS), as well as mixed-signal electronic designs.
    In STL−MX, properties of components with continuous dynamics are expressed in
    STL, while specifications of components with discrete dynamics are written in
    LTL. To combine the two layers, we evaluate formulas on two traces, discrete-
    and continuous-time, and introduce two interface operators that map signals, properties
    and their satisfaction signals across the two time domains. We show that STL-mx
    has the expressive power of STL supplemented with an implicit T-periodic clock
    signal. We develop and implement an algorithm for monitoring STL-mx formulas and
    illustrate the approach using a mixed-signal example. '

  text: We illustrate the ingredients of the state-of-the-art of model-based approach
    for the formal design and verification of cyber-physical systems. To capture the
    interaction between a discrete controller and its continuously evolving environment,
    we use the formal models of timed and hybrid automata. We explain the steps of
    modeling and verification in the tools Uppaal and SpaceEx using a case study based
    on a dual-chamber implantable pacemaker monitoring a human heart. We show how
    to design a model as a composition of components, how to construct models at varying
    levels of detail, how to establish that one model is an abstraction of another,
    how to specify correctness requirements using temporal logic, and how to verify
    that a model satisfies a logical requirement.

  text: We present the results of a friendly competition for formal verification of
    continuous and hybrid systems with nonlinear continuous dynamics. The friendly
    competition took place as part of the workshop Applied Verification for Continuous
    and Hybrid Systems (ARCH) in 2019. In this year, 6 tools Ariadne, CORA, DynIbex,
    Flow*, Isabelle/HOL, and JuliaReach (in alphabetic order) participated. They are
    applied to solve reachability analysis problems on four benchmark problems, one
    of them with hybrid dynamics. We do not rank the tools based on the results, but
    show the current status and discover the potential advantages of different tools.

  text: 'We present JuliaReach, a toolbox for set-based reachability analysis of dynamical
    systems. JuliaReach consists of two main packages: Reachability, containing implementations
    of reachability algorithms for continuous and hybrid systems, and LazySets, a
    standalone library that implements state-of-the-art algorithms for calculus with
    convex sets. The library offers both concrete and lazy set representations, where
    the latter stands for the ability to delay set computations until they are needed.
    The choice of the programming language Julia and the accompanying documentation
    of our toolbox allow researchers to easily translate set-based algorithms from
    mathematics to software in a platform-independent way, while achieving runtime
    performance that is comparable to statically compiled languages. Combining lazy
    operations in high dimensions and explicit computations in low dimensions, JuliaReach
    can be applied to solve complex, large-scale problems.'

  text: Static program analyzers are increasingly effective in checking correctness
    properties of programs and reporting any errors found, often in the form of error
    traces. However, developers still spend a significant amount of time on debugging.
    This involves processing long error traces in an effort to localize a bug to a
    relatively small part of the program and to identify its cause. In this paper,
    we present a technique for automated fault localization that, given a program
    and an error trace, efficiently narrows down the cause of the error to a few statements.
    These statements are then ranked in terms of their suspiciousness. Our technique
    relies only on the semantics of the given program and does not require any test
    cases or user guidance. In experiments on a set of C benchmarks, we show that
    our technique is effective in quickly isolating the cause of error while out-performing
    other state-of-the-art fault-localization techniques.

  text: 'Safety and security are major concerns in the development of Cyber-Physical
    Systems (CPS). Signal temporal logic (STL) was proposedas a language to specify
    and monitor the correctness of CPS relativeto formalized requirements. Incorporating
    STL into a developmentprocess enables designers to automatically monitor and diagnosetraces,
    compute robustness estimates based on requirements, andperform requirement falsification,
    leading to productivity gains inverification and validation activities; however,
    in its current formSTL is agnostic to the input/output classification of signals,
    andthis negatively impacts the relevance of the analysis results.In this paper
    we propose to make the interface explicit in theSTL language by introducing input/output
    signal declarations. Wethen define new measures of input vacuity and output robustnessthat
    better reflect the nature of the system and the specification in-tent. The resulting
    framework, which we call interface-aware signaltemporal logic (IA-STL), aids verification
    and validation activities.We demonstrate the benefits of IA-STL on several CPS
    analysisactivities: (1) robustness-driven sensitivity analysis, (2) falsificationand
    (3) fault localization. We describe an implementation of our en-hancement to STL
    and associated notions of robustness and vacuityin a prototype extension of Breach,
    a MATLAB®/Simulink®toolboxfor CPS verification and validation. We explore these
    methodologi-cal improvements and evaluate our results on two examples fromthe
    automotive domain: a benchmark powertrain control systemand a hydrogen fuel cell
    system.'

  text: A controller is a device that interacts with a plant. At each time point,it
    reads the plant’s state and issues commands with the goal that the plant oper-ates
    optimally. Constructing optimal controllers is a fundamental and challengingproblem.
    Machine learning techniques have recently been successfully applied totrain controllers,
    yet they have limitations. Learned controllers are monolithic andhard to reason
    about. In particular, it is difficult to add features without retraining,to guarantee
    any level of performance, and to achieve acceptable performancewhen encountering
    untrained scenarios. These limitations can be addressed bydeploying quantitative
    run-timeshieldsthat serve as a proxy for the controller.At each time point, the
    shield reads the command issued by the controller andmay choose to alter it before
    passing it on to the plant. We show how optimalshields that interfere as little
    as possible while guaranteeing a desired level ofcontroller performance, can be
    generated systematically and automatically usingreactive  synthesis.  First,  we  abstract  the  plant  by  building  a  stochastic  model.Second,
    we consider the learned controller to be a black box. Third, we mea-surecontroller
    performanceandshield interferenceby two quantitative run-timemeasures that are
    formally defined using weighted automata. Then, the problemof constructing a shield
    that guarantees maximal performance with minimal inter-ference is the problem
    of finding an optimal strategy in a stochastic2-player game“controller versus
    shield” played on the abstract state space of the plant with aquantitative objective
    obtained from combining the performance and interferencemeasures. We illustrate
    the effectiveness of our approach by automatically con-structing lightweight shields
    for learned traffic-light controllers in various roadnetworks. The shields we
    generate avoid liveness bugs, improve controller per-formance in untrained and
    changing traffic situations, and add features to learnedcontrollers, such as giving
    priority to emergency vehicles.

  text: We present two algorithmic approaches for synthesizing linear hybrid automata
    from experimental data. Unlike previous approaches, our algorithms work without
    a template and generate an automaton with nondeterministic guards and invariants,
    and with an arbitrary number and topology of modes. They thus construct a succinct
    model from the data and provide formal guarantees. In particular, (1) the generated
    automaton can reproduce the data up to a specified tolerance and (2) the automaton
    is tight, given the first guarantee. Our first approach encodes the synthesis
    problem as a logical formula in the theory of linear arithmetic, which can then
    be solved by an SMT solver. This approach minimizes the number of modes in the
    resulting model but is only feasible for limited data sets. To address scalability,
    we propose a second approach that does not enforce to find a minimal model. The
    algorithm constructs an initial automaton and then iteratively extends the automaton
    based on processing new data. Therefore the algorithm is well-suited for online
    and synthesis-in-the-loop applications. The core of the algorithm is a membership
    query that checks whether, within the specified tolerance, a given data set can
    result from the execution of a given automaton. We solve this membership problem
    for linear hybrid automata by repeated reachability computations. We demonstrate
    the effectiveness of the algorithm on synthetic data sets and on cardiac-cell
    measurements.

  text: In this paper, we address the problem of synthesizing periodic switching controllers
    for stabilizing a family of linear systems. Our broad approach consists of constructing
    a finite game graph based on the family of linear systems such that every winning
    strategy on the game graph corresponds to a stabilizing switching controller for
    the family of linear systems. The construction of a (finite) game graph, the synthesis
    of a winning strategy and the extraction of a stabilizing controller are all computationally
    feasible. We illustrate our method on an example.

  text: Graph games played by two players over finite-state graphs are central in
    many problems in computer science. In particular, graph games with ω -regular
    winning conditions, specified as parity objectives, which can express properties
    such as safety, liveness, fairness, are the basic framework for verification and
    synthesis of reactive systems. The decisions for a player at various states of
    the graph game are represented as strategies. While the algorithmic problem for
    solving graph games with parity objectives has been widely studied, the most prominent
    data-structure for strategy representation in graph games has been binary decision
    diagrams (BDDs). However, due to the bit-level representation, BDDs do not retain
    the inherent flavor of the decisions of strategies, and are notoriously hard to
    minimize to obtain succinct representation. In this work we propose decision trees
    for strategy representation in graph games. Decision trees retain the flavor of
    decisions of strategies and allow entropy-based minimization to obtain succinct
    trees. However, decision trees work in settings (e.g., probabilistic models) where
    errors are allowed, and overfitting of data is typically avoided. In contrast,
    for strategies in graph games no error is allowed, and the decision tree must
    represent the entire strategy. We develop new techniques to extend decision trees
    to overcome the above obstacles, while retaining the entropy-based techniques
    to obtain succinct trees. We have implemented our techniques to extend the existing
    decision tree solvers. We present experimental results for problems in reactive
    synthesis to show that decision trees provide a much more efficient data-structure
    for strategy representation as compared to BDDs.

  text: We introduce in this paper   AMT 2.0 , a tool for qualitative and quantitative
    analysis of hybrid continuous and Boolean signals that combine numerical values
    and discrete events. The evaluation of the signals is based on rich temporal specifications
    expressed in extended Signal Temporal Logic (xSTL), which integrates Timed Regular
    Expressions (TRE) within Signal Temporal Logic (STL). The tool features qualitative
    monitoring (property satisfaction checking), trace diagnostics for explaining
    and justifying property violations and specification-driven measurement of quantitative
    features of the signal.

  text: "This book first explores the origins of this idea, grounded in theoretical
    work on temporal logic and automata. The editors and authors are among the world's
    leading researchers in this domain, and they contributed 32 chapters representing
    a thorough view of the development and application of the technique. Topics covered
    include binary decision diagrams, symbolic model checking, satisfiability modulo
    theories, partial-order reduction, abstraction, interpolation, concurrency, security
    protocols, games, probabilistic model checking, and process algebra, and chapters
    on the transfer of theory to industrial practice, property specification languages
    for hardware, and verification of real-time systems and hybrid systems.\r\n\r\nThe
    book will be valuable for researchers and graduate students engaged with the development
    of formal methods and verification tools."
