  text: We introduce the monitoring of trace properties under assumptions. An assumption
    limits the space of possible traces that the monitor may encounter. An assumption
    may result from knowledge about the system that is being monitored, about the
    environment, or about another, connected monitor. We define monitorability under
    assumptions and study its theoretical properties. In particular, we show that
    for every assumption A, the boolean combinations of properties that are safe or
    co-safe relative to A are monitorable under A. We give several examples and constructions
    on how an assumption can make a non-monitorable property monitorable, and how
    an assumption can make a monitorable property monitorable with fewer resources,
    such as integer registers.

  text: A central goal of artificial intelligence in high-stakes decision-making applications
    is to design a single algorithm that simultaneously expresses generalizability
    by learning coherent representations of their world and interpretable explanations
    of its dynamics. Here, we combine brain-inspired neural computation principles
    and scalable deep learning architectures to design compact neural controllers
    for task-specific compartments of a full-stack autonomous vehicle control system.
    We discover that a single algorithm with 19 control neurons, connecting 32 encapsulated
    input features to outputs by 253 synapses, learns to map high-dimensional inputs
    into steering commands. This system shows superior generalizability, interpretability
    and robustness compared with orders-of-magnitude larger black-box learning systems.
    The obtained neural agents enable high-fidelity autonomy for task-specific parts
    of a complex autonomous system.

  text: Traditional robotic control suits require profound task-specific knowledge
    for designing, building and testing control software. The rise of Deep Learning
    has enabled end-to-end solutions to be learned entirely from data, requiring minimal
    knowledge about the application area. We design a learning scheme to train end-to-end
    linear dynamical systems (LDS)s by gradient descent in imitation learning robotic
    domains. We introduce a new regularization loss component together with a learning
    algorithm that improves the stability of the learned autonomous system, by forcing
    the eigenvalues of the internal state updates of an LDS to be negative reals.
    We evaluate our approach on a series of real-life and simulated robotic experiments,
    in comparison to linear and nonlinear Recurrent Neural Network (RNN) architectures.
    Our results show that our stabilizing method significantly improves test performance
    of LDS, enabling such linear models to match the performance of contemporary nonlinear
    RNN architectures. A video of the obstacle avoidance performance of our method
    on a mobile robot, in unseen environments, compared to other methods can be viewed
    at https://youtu.be/mhEsCoNao5E.

  text: "Efficiently handling time-triggered and possibly nondeterministic switches\r\nfor
    hybrid systems reachability is a challenging task. In this paper we present\r\nan
    approach based on conservative set-based enclosure of the dynamics that can\r\nhandle
    systems with uncertain parameters and inputs, where the uncertainties\r\nare bound
    to given intervals. The method is evaluated on the plant model of an\r\nexperimental
    electro-mechanical braking system with periodic controller. In\r\nthis model,
    the fast-switching controller dynamics requires simulation time\r\nscales of the
    order of nanoseconds. Accurate set-based computations for\r\nrelatively large
    time horizons are known to be expensive. However, by\r\nappropriately decoupling
    the time variable with respect to the spatial\r\nvariables, and enclosing the
    uncertain parameters using interval matrix maps\r\nacting on zonotopes, we show
    that the computation time can be lowered to 5000\r\ntimes faster with respect
    to previous works. This is a step forward in formal\r\nverification of hybrid
    systems because reduced run-times allow engineers to\r\nintroduce more expressiveness
    in their models with a relatively inexpensive\r\ncomputational cost."

  text: Reachability analysis aims at identifying states reachable by a system within
    a given time horizon. This task is known to be computationally expensive for linear
    hybrid systems. Reachability analysis works by iteratively applying continuous
    and discrete post operators to compute states reachable according to continuous
    and discrete dynamics, respectively. In this article, we enhance both of these
    operators and make sure that most of the involved computations are performed in
    low-dimensional state space. In particular, we improve the continuous-post operator
    by performing computations in high-dimensional state space only for time intervals
    relevant for the subsequent application of the discrete-post operator. Furthermore,
    the new discrete-post operator performs low-dimensional computations by leveraging
    the structure of the guard and assignment of a considered transition. We illustrate
    the potential of our approach on a number of challenging benchmarks.

  text: In resource allocation games, selfish players share resources that are needed
    in order to fulfill their objectives. The cost of using a resource depends on
    the load on it. In the traditional setting, the players make their choices concurrently
    and in one-shot. That is, a strategy for a player is a subset of the resources.
    We introduce and study dynamic resource allocation games. In this setting, the
    game proceeds in phases. In each phase each player chooses one resource. A scheduler
    dictates the order in which the players proceed in a phase, possibly scheduling
    several players to proceed concurrently. The game ends when each player has collected
    a set of resources that fulfills his objective. The cost for each player then
    depends on this set as well as on the load on the resources in it – we consider
    both congestion and cost-sharing games. We argue that the dynamic setting is the
    suitable setting for many applications in practice. We study the stability of
    dynamic resource allocation games, where the appropriate notion of stability is
    that of subgame perfect equilibrium, study the inefficiency incurred due to selfish
    behavior, and also study problems that are particular to the dynamic setting,
    like constraints on the order in which resources can be chosen or the problem
    of finding a scheduler that achieves stability.

  text: 'The monitoring of event frequencies can be used to recognize behavioral anomalies,
    to identify trends, and to deduce or discard hypotheses about the underlying system.
    For example, the performance of a web server may be monitored based on the ratio
    of the total count of requests from the least and most active clients. Exact frequency
    monitoring, however, can be prohibitively expensive; in the above example it would
    require as many counters as there are clients. In this paper, we propose the efficient
    probabilistic monitoring of common frequency properties, including the mode (i.e.,
    the most common event) and the median of an event sequence. We define a logic
    to express composite frequency properties as a combination of atomic frequency
    properties. Our main contribution is an algorithm that, under suitable probabilistic
    assumptions, can be used to monitor these important frequency properties with
    four counters, independent of the number of different events. Our algorithm samples
    longer and longer subwords of an infinite event sequence. We prove the almost-sure
    convergence of our algorithm by generalizing ergodic theory from increasing-length
    prefixes to increasing-length subwords of an infinite sequence. A similar algorithm
    could be used to learn a connected Markov chain of a given structure from observing
    its outputs, to arbitrary precision, for a given confidence. '

  text: This paper presents a novel abstraction technique for analyzing Lyapunov and
    asymptotic stability of polyhedral switched systems. A polyhedral switched system
    is a hybrid system in which the continuous dynamics is specified by polyhedral
    differential inclusions, the invariants and guards are specified by polyhedral
    sets and the switching between the modes do not involve reset of variables. A
    finite state weighted graph abstracting the polyhedral switched system is constructed
    from a finite partition of the state–space, such that the satisfaction of certain
    graph conditions, such as the absence of cycles with product of weights on the
    edges greater than (or equal) to 1, implies the stability of the system. However,
    the graph is in general conservative and hence, the violation of the graph conditions
    does not imply instability. If the analysis fails to establish stability due to
    the conservativeness in the approximation, a counterexample (cycle with product
    of edge weights greater than or equal to 1) indicating a potential reason for
    the failure is returned. Further, a more precise approximation of the switched
    system can be constructed by considering a finer partition of the state–space
    in the construction of the finite weighted graph. We present experimental results
    on analyzing stability of switched systems using the above method.

  text: Neural networks have demonstrated unmatched performance in a range of classification
    tasks. Despite numerous efforts of the research community, novelty detection remains
    one of the significant limitations of neural networks. The ability to identify
    previously unseen inputs as novel is crucial for our understanding of the decisions
    made by neural networks. At runtime, inputs not falling into any of the categories
    learned during training cannot be classified correctly by the neural network.
    Existing approaches treat the neural network as a black box and try to detect
    novel inputs based on the confidence of the output predictions. However, neural
    networks are not trained to reduce their confidence for novel inputs, which limits
    the effectiveness of these approaches. We propose a framework to monitor a neural
    network by observing the hidden layers. We employ a common abstraction from program
    analysis - boxes - to identify novel behaviors in the monitored layers, i.e.,
    inputs that cause behaviors outside the box. For each neuron, the boxes range
    over the values seen in training. The framework is efficient and flexible to achieve
    a desired trade-off between raising false warnings and detecting novel inputs.
    We illustrate the performance and the robustness to variability in the unknown
    classes on popular image-classification benchmarks.

  text: Machine learning and formal methods have complimentary benefits and drawbacks.
    In this work, we address the controller-design problem with a combination of techniques
    from both fields. The use of black-box neural networks in deep reinforcement learning
    (deep RL) poses a challenge for such a combination. Instead of reasoning formally
    about the output of deep RL, which we call the wizard, we extract from it a decision-tree
    based model, which we refer to as the magic book. Using the extracted model as
    an intermediary, we are able to handle problems that are infeasible for either
    deep RL or formal methods by themselves. First, we suggest, for the first time,
    a synthesis procedure that is based on a magic book. We synthesize a stand-alone
    correct-by-design controller that enjoys the favorable performance of RL. Second,
    we incorporate a magic book in a bounded model checking (BMC) procedure. BMC allows
    us to find numerous traces of the plant under the control of the wizard, which
    a user can use to increase the trustworthiness of the wizard and direct further
    training.

  text: 'We introduce LRT-NG, a set of techniques and an associated toolset that computes
    a reachtube (an over-approximation of the set of reachable states over a given
    time horizon) of a nonlinear dynamical system. LRT-NG significantly advances the
    state-of-the-art Langrangian Reachability and its associated tool LRT. From a
    theoretical perspective, LRT-NG is superior to LRT in three ways. First, it uses
    for the first time an analytically computed metric for the propagated ball which
    is proven to minimize the ball’s volume. We emphasize that the metric computation
    is the centerpiece of all bloating-based techniques. Secondly, it computes the
    next reachset as the intersection of two balls: one based on the Cartesian metric
    and the other on the new metric. While the two metrics were previously considered
    opposing approaches, their joint use considerably tightens the reachtubes. Thirdly,
    it avoids the "wrapping effect" associated with the validated integration of the
    center of the reachset, by optimally absorbing the interval approximation in the
    radius of the next ball. From a tool-development perspective, LRT-NG is superior
    to LRT in two ways. First, it is a standalone tool that no longer relies on CAPD.
    This required the implementation of the Lohner method and a Runge-Kutta time-propagation
    method. Secondly, it has an improved interface, allowing the input model and initial
    conditions to be provided as external input files. Our experiments on a comprehensive
    set of benchmarks, including two Neural ODEs, demonstrates LRT-NG’s superior performance
    compared to LRT, CAPD, and Flow*.'

    player, zero-sum games on graphs. The game proceeds as follows. We place a token
    on some vertex in the graph and assign budgets to the two players. Each turn,
    each player submits a sealed legal bid (non-negative and below their remaining
    budget), which is deducted from their budget and the highest bidder moves the
    token onto an adjacent vertex. The game ends once a sink is reached, and Player
    1 pays Player 2 the outcome that is associated with the sink. The players attempt
    to maximize their expected outcome. Our games model settings where effort (of
    no inherent value) needs to be invested in an ongoing and stateful manner. On
    the negative side, we show that even in simple games on DAGs, optimal strategies
    may require a distribution over bids with infinite support. A central quantity
    in bidding games is the ratio of the players budgets. On the positive side, we
    show a simple FPTAS for DAGs, that, for each budget ratio, outputs an approximation
    for the optimal strategy for that ratio. We also implement it, show that it performs
    well, and suggests interesting properties of these games. Then, given an outcome
    c, we show an algorithm for finding the necessary and sufficient initial ratio
    for guaranteeing outcome c with probability 1 and a strategy ensuring such. Finally,
    while the general case has not previously been studied, solving the specific game
    in which Player 1 wins iff he wins the first two auctions, has been long stated
    as an open question, which we solve.

  text: We propose a novel hybridization method for stability analysis that over-approximates
    nonlinear dynamical systems by switched systems with linear inclusion dynamics.
    We observe that existing hybridization techniques for safety analysis that over-approximate
    nonlinear dynamical systems by switched affine inclusion dynamics and provide
    fixed approximation error, do not suffice for stability analysis. Hence, we propose
    a hybridization method that provides a state-dependent error which converges to
    zero as the state tends to the equilibrium point. The crux of our hybridization
    computation is an elegant recursive algorithm that uses partial derivatives of
    a given function to obtain upper and lower bound matrices for the over-approximating
    linear inclusion. We illustrate our method on some examples to demonstrate the
    application of the theory for stability analysis. In particular, our method is
    able to establish stability of a nonlinear system which does not admit a polynomial
    Lyapunov function.

  text: "Second-order information, in the form of Hessian- or Inverse-Hessian-vector
    products, is a fundamental tool for solving optimization problems. Recently, there
    has been significant interest in utilizing this information in the context of
    deep\r\nneural networks; however, relatively little is known about the quality
    of existing approximations in this context. Our work examines this question, identifies
    issues with existing approaches, and proposes a method called WoodFisher to compute
    a faithful and efficient estimate of the inverse Hessian. Our main application
    is to neural network compression, where we build on the classic Optimal Brain
    Damage/Surgeon framework. We demonstrate that WoodFisher significantly outperforms
    popular state-of-the-art methods for oneshot pruning. Further, even when iterative,
    gradual pruning is allowed, our method results in a gain in test accuracy over
    the state-of-the-art approaches, for standard image classification datasets such
    as ImageNet ILSVRC. We examine how our method can be extended to take into account
    first-order information, as well as\r\nillustrate its ability to automatically
    set layer-wise pruning thresholds and perform compression in the limited-data
    regime. The code is available at the following link, https://github.com/IST-DASLab/WoodFisher."

  text: 'This report presents the results of a friendly competition for formal verification
    of continuous and hybrid systems with piecewise constant dynamics. The friendly
    competition took place as part of the workshop Applied Verification for Continuous
    and Hybrid Systems (ARCH) in 2019. In this third edition, six tools have been
    applied to solve five different benchmark problems in the category for piecewise
    constant dynamics: BACH, Lyse, Hy- COMP, PHAVer/SX, PHAVerLite, and VeriSiMPL.
    Compared to last year, a new tool has participated (HyCOMP) and PHAVerLite has
    replaced PHAVer-lite. The result is a snap- shot of the current landscape of tools
    and the types of benchmarks they are particularly suited for. Due to the diversity
    of problems, we are not ranking tools, yet the presented results probably provide
    the most complete assessment of tools for the safety verification of continuous
    and hybrid systems with piecewise constant dynamics up to this date.'

  text: 'This report presents the results of a friendly competition for formal verification
    of continuous and hybrid systems with linear continuous dynamics. The friendly
    competition took place as part of the workshop Applied Verification for Continuous
    and Hybrid Systems (ARCH) in 2019. In its third edition, seven tools have been
    applied to solve six different benchmark problems in the category for linear continuous
    dynamics (in alphabetical order): CORA, CORA/SX, HyDRA, Hylaa, JuliaReach, SpaceEx,
    and XSpeed. This report is a snapshot of the current landscape of tools and the
    types of benchmarks they are particularly suited for. Due to the diversity of
    problems, we are not ranking tools, yet the presented results provide one of the
    most complete assessments of tools for the safety verification of continuous and
    hybrid systems with linear continuous dynamics up to this date.</jats:p>'

  text: 'Two-player games on graphs are widely studied in formal methods, as they
    model the interaction between a system and its environment. The game is played
    by moving a token throughout a graph to produce an infinite path. There are several
    common modes to determine how the players move the token through the graph; e.g.,
    in turn-based games the players alternate turns in moving the token. We study
    the bidding mode of moving the token, which, to the best of our knowledge, has
    never been studied in infinite-duration games. The following bidding rule was
    previously defined and called Richman bidding. Both players have separate budgets,
    which sum up to 1. In each turn, a bidding takes place: Both players submit bids
    simultaneously, where a bid is legal if it does not exceed the available budget,
    and the higher bidder pays his bid to the other player and moves the token. The
    central question studied in bidding games is a necessary and sufficient initial
    budget for winning the game: a threshold budget in a vertex is a value t ∈ [0,
    1] such that if Player 1’s budget exceeds t, he can win the game; and if Player
    2’s budget exceeds 1 − t, he can win the game. Threshold budgets were previously
    shown to exist in every vertex of a reachability game, which have an interesting
    connection with random-turn games—a sub-class of simple stochastic games in which
    the player who moves is chosen randomly. We show the existence of threshold budgets
    for a qualitative class of infinite-duration games, namely parity games, and a
    quantitative class, namely mean-payoff games. The key component of the proof is
    a quantitative solution to strongly connected mean-payoff bidding games in which
    we extend the connection with random-turn games to these games, and construct
    explicit optimal strategies for both players.'

  text: "In two-player games on graphs, the players move a token through a graph to
    produce an infinite path, which determines the qualitative winner or quantitative
    payoff of the game. In bidding games, in each turn, we hold an auction between
    the two players to determine which player moves the token. Bidding games have
    largely been studied with concrete bidding mechanisms that are variants of a first-price
    auction: in each turn both players simultaneously submit bids, the higher\r\nbidder
    moves the token, and pays his bid to the lower bidder in Richman bidding, to the
    bank in poorman bidding, and in taxman bidding, the bid is split between the other
    player and the bank according to a predefined constant factor. Bidding games are
    deterministic games. They have an intriguing connection with a fragment of stochastic
    games called \r\n randomturn games. We study, for the first time, a combination
    of bidding games with probabilistic behavior; namely, we study bidding games that
    are played on Markov decision processes, where the players bid for the right to
    choose the next action, which determines the probability distribution according
    to which the next vertex is chosen. We study parity and meanpayoff bidding games
    on MDPs and extend results from the deterministic bidding setting to the probabilistic
    one."

  text: 'In two-player games on graphs, the players move a token through a graph to
    produce a finite or infinite path, which determines the qualitative winner or
    quantitative payoff of the game. We study bidding games in which the players bid
    for the right to move the token. Several bidding rules were studied previously.
    In Richman bidding, in each round, the players simultaneously submit bids, and
    the higher bidder moves the token and pays the other player. Poorman bidding is
    similar except that the winner of the bidding pays the "bank" rather than the
    other player. Taxman bidding spans the spectrum between Richman and poorman bidding.
    They are parameterized by a constant tau in [0,1]: portion tau of the winning
    bid is paid to the other player, and portion 1-tau to the bank. While finite-duration
    (reachability) taxman games have been studied before, we present, for the first
    time, results on infinite-duration taxman games. It was previously shown that
    both Richman and poorman infinite-duration games with qualitative objectives reduce
    to reachability games, and we show a similar result here. Our most interesting
    results concern quantitative taxman games, namely mean-payoff games, where poorman
    and Richman bidding differ significantly. A central quantity in these games is
    the ratio between the two players'' initial budgets. While in poorman mean-payoff
    games, the optimal payoff of a player depends on the initial ratio, in Richman
    bidding, the payoff depends only on the structure of the game. In both games the
    optimal payoffs can be found using (different) probabilistic connections with
    random-turn games in which in each turn, instead of bidding, a coin is tossed
    to determine which player moves. While the value with Richman bidding equals the
    value of a random-turn game with an un-biased coin, with poorman bidding, the
    bias in the coin is the initial ratio of the budgets. We give a complete classification
    of mean-payoff taxman games that is based on a probabilistic connection: the value
    of a taxman bidding game with parameter tau and initial ratio r, equals the value
    of a random-turn game that uses a coin with bias F(tau, r) = (r+tau * (1-r))/(1+tau).
    Thus, we show that Richman bidding is the exception; namely, for every tau <1,
    the value of the game depends on the initial ratio. Our proof technique simplifies
    and unifies the previous proof techniques for both Richman and poorman bidding. '

  text: 'A vector addition system with states (VASS) consists of a finite set of states
    and counters. A configuration is a state and a value for each counter; a transition
    changes the state and each counter is incremented, decremented, or left unchanged.
    While qualitative properties such as state and configuration reachability have
    been studied for VASS, we consider the long-run average cost of infinite computations
    of VASS. The cost of a configuration is for each state, a linear combination of
    the counter values. In the special case of uniform cost functions, the linear
    combination is the same for all states. The (regular) long-run emptiness problem
    is, given a VASS, a cost function, and a threshold value, if there is a (lasso-shaped)
    computation such that the long-run average value of the cost function does not
    exceed the threshold. For uniform cost functions, we show that the regular long-run
    emptiness problem is (a) decidable in polynomial time for integer-valued VASS,
    and (b) decidable but nonelementarily hard for natural-valued VASS (i.e., nonnegative
    counters). For general cost functions, we show that the problem is (c) NP-complete
    for integer-valued VASS, and (d) undecidable for natural-valued VASS. Our most
    interesting result is for (c) integer-valued VASS with general cost functions,
    where we establish a connection between the regular long-run emptiness problem
    and quadratic Diophantine inequalities. The general (nonregular) long-run emptiness
    problem is equally hard as the regular problem in all cases except (c), where
    it remains open. '
