  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 introduce and study all-pay bidding games, a class of two
    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: 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: 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: '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: '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: Network games are widely used as a model for selfish resource-allocation problems.
    In the classicalmodel, each player selects a path connecting her source and target
    vertices. The cost of traversingan edge depends on theload; namely, number of
    players that traverse it. Thus, it abstracts the factthat different users may
    use a resource at different times and for different durations, which playsan important
    role in determining the costs of the users in reality. For example, when transmittingpackets
    in a communication network, routing traffic in a road network, or processing a
    task in aproduction system, actual sharing and congestion of resources crucially
    depends on time.In [13], we introducedtimed network games, which add a time component
    to network games.Each vertexvin the network is associated with a cost function,
    mapping the load onvto theprice that a player pays for staying invfor one time
    unit with this load.  Each edge in thenetwork is guarded by the time intervals
    in which it can be traversed, which forces the players tospend time in the vertices.
    In this work we significantly extend the way time can be referred toin timed network
    games. In the model we study, the network is equipped withclocks, and, as intimed
    automata, edges are guarded by constraints on the values of the clocks, and their
    traversalmay involve a reset of some clocks. We argue that the stronger model
    captures many realisticnetworks.  The addition of clocks breaks the techniques
    we developed in [13] and we developnew techniques in order to show that positive
    results on classic network games carry over to thestronger timed setting.

  text: 'Network games (NGs) are played on directed graphs and are extensively used
    in network design and analysis. Search problems for NGs include finding special
    strategy profiles such as a Nash equilibrium and a globally-optimal solution.
    The networks modeled by NGs may be huge. In formal verification, abstraction has
    proven to be an extremely effective technique for reasoning about systems with
    big and even infinite state spaces. We describe an abstraction-refinement methodology
    for reasoning about NGs. Our methodology is based on an abstraction function that
    maps the state space of an NG to a much smaller state space. We search for a global
    optimum and a Nash equilibrium by reasoning on an under- and an over-approximation
    defined on top of this smaller state space. When the approximations are too coarse
    to find such profiles, we refine the abstraction function. We extend the abstraction-refinement
    methodology to labeled networks, where the objectives of the players are regular
    languages. Our experimental results demonstrate the effectiveness of the methodology. '

  text: In two-player games on graphs, the players move a token through a graph to
    produce an infinite path, which determines the winner or payoff of the game. Such
    games are central in formal verification since they model the interaction between
    a non-terminating system and its environment. We study bidding games in which
    the players bid for the right to move the token. Two bidding rules have been defined.
    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. While poorman reachability games have been studied before, we present,
    for the first time, results on infinite-duration poorman games. A central quantity
    in these games is the ratio between the two players’ initial budgets. The questions
    we study concern a necessary and sufficient ratio with which a player can achieve
    a goal. For reachability objectives, such threshold ratios are known to exist
    for both bidding rules. We show that the properties of poorman reachability games
    extend to complex qualitative objectives such as parity, similarly to the Richman
    case. Our most interesting results concern quantitative poorman games, namely
    poorman mean-payoff games, where we construct optimal strategies depending on
    the initial ratio, by showing a connection with random-turn based games. The connection
    in itself is interesting, because it does not hold for reachability poorman games.
    We also solve the complexity problems that arise in poorman bidding games.
