  text: Indirect reciprocity explores how humans act when their reputation is at stake,
    and which social norms they use to assess the actions of others. A crucial question
    in indirect reciprocity is which social norms can maintain stable cooperation
    in a society. Past research has highlighted eight such norms, called “leading-eight”
    strategies. This past research, however, is based on the assumption that all relevant
    information about other population members is publicly available and that everyone
    agrees on who is good or bad. Instead, here we explore the reputation dynamics
    when information is private and noisy. We show that under these conditions, most
    leading-eight strategies fail to evolve. Those leading-eight strategies that do
    evolve are unable to sustain full cooperation.Indirect reciprocity is a mechanism
    for cooperation based on shared moral systems and individual reputations. It assumes
    that members of a community routinely observe and assess each other and that they
    use this information to decide who is good or bad, and who deserves cooperation.
    When information is transmitted publicly, such that all community members agree
    on each other’s reputation, previous research has highlighted eight crucial moral
    systems. These “leading-eight” strategies can maintain cooperation and resist
    invasion by defectors. However, in real populations individuals often hold their
    own private views of others. Once two individuals disagree about their opinion
    of some third party, they may also see its subsequent actions in a different light.
    Their opinions may further diverge over time. Herein, we explore indirect reciprocity
    when information transmission is private and noisy. We find that in the presence
    of perception errors, most leading-eight strategies cease to be stable. Even if
    a leading-eight strategy evolves, cooperation rates may drop considerably when
    errors are common. Our research highlights the role of reliable information and
    synchronized reputations to maintain stable moral systems.

  text: 'Crypto-currencies are digital assets designed to work as a medium of exchange,
    e.g., Bitcoin, but they are susceptible to attacks (dishonest behavior of participants).
    A framework for the analysis of attacks in crypto-currencies requires (a) modeling
    of game-theoretic aspects to analyze incentives for deviation from honest behavior;
    (b) concurrent interactions between participants; and (c) analysis of long-term
    monetary gains. Traditional game-theoretic approaches for the analysis of security
    protocols consider either qualitative temporal properties such as safety and termination,
    or the very special class of one-shot (stateless) games. However, to analyze general
    attacks on protocols for crypto-currencies, both stateful analysis and quantitative
    objectives are necessary. In this work our main contributions are as follows:
    (a) we show how a class of concurrent mean-payo games, namely ergodic games, can
    model various attacks that arise naturally in crypto-currencies; (b) we present
    the first practical implementation of algorithms for ergodic games that scales
    to model realistic problems for crypto-currencies; and (c) we present experimental
    results showing that our framework can handle games with thousands of states and
    millions of transitions.'

  text: 'Smart contracts are computer programs that are executed by a network of mutually
    distrusting agents, without the need of an external trusted authority. Smart contracts
    handle and transfer assets of considerable value (in the form of crypto-currency
    like Bitcoin). Hence, it is crucial that their implementation is bug-free. We
    identify the utility (or expected payoff) of interacting with such smart contracts
    as the basic and canonical quantitative property for such contracts. We present
    a framework for such quantitative analysis of smart contracts. Such a formal framework
    poses new and novel research challenges in programming languages, as it requires
    modeling of game-theoretic aspects to analyze incentives for deviation from honest
    behavior and modeling utilities which are not specified as standard temporal properties
    such as safety and termination. While game-theoretic incentives have been analyzed
    in the security community, their analysis has been restricted to the very special
    case of stateless games. However, to analyze smart contracts, stateful analysis
    is required as it must account for the different program states of the protocol.
    Our main contributions are as follows: we present (i)~a simplified programming
    language for smart contracts; (ii)~an automatic translation of the programs to
    state-based games; (iii)~an abstraction-refinement approach to solve such games;
    and (iv)~experimental results on real-world-inspired smart contracts.'

  text: We  present  a  secure  approach  for  maintaining  andreporting  credit  history  records  on  the  Blockchain.  Our  ap-proach  removes  third-parties  such  as  credit  reporting  agen-cies  from  the  lending  process  and  replaces  them  with  smartcontracts.  This  allows  customers  to  interact  directly  with  thelenders  or  banks  while  ensuring  the  integrity,  unmalleabilityand  privacy  of  their  credit  data.  Additionally,  each  customerhas  full  control  over  complete  or  selective  disclosure  of  hercredit
    records, eliminating the risk of privacy violations or databreaches. Moreover,
    our approach provides strong guaranteesfor the lenders as well. A lender can check
    both correctness andcompleteness of the credit data disclosed to her. This is
    the firstapproach  that  can  perform  all  credit  reporting  tasks  withouta  central  authority  or  changing  the  financial  mechanisms*.

  text: "We study algorithmic questions wrt algebraic path properties in concurrent
    systems, where the transitions of the system are labeled from a complete, closed
    semiring. The algebraic path properties can model dataflow analysis problems,
    the shortest path problem, and many other natural problems that arise in program
    analysis. We consider that each component of the concurrent system is a graph
    with constant treewidth, a property satisfied by the controlflow graphs of most
    programs. We allow for multiple possible queries, which arise naturally in demand
    driven dataflow analysis. The study of multiple queries allows us to consider
    the tradeoff between the resource usage of the one-time preprocessing and for
    each individual query. The traditional approach constructs the product graph of
    all components and applies the best-known graph algorithm on the product. In this
    approach, even the answer to a single query requires the transitive closure (i.e.,
    the results of all possible queries), which provides no room for tradeoff between
    preprocessing and query time.\r\nOur main contributions are algorithms that significantly
    improve the worst-case running time of the traditional approach, and provide various
    tradeoffs depending on the number of queries. For example, in a concurrent system
    of two components, the traditional approach requires hexic time in the worst case
    for answering one query as well as computing the transitive closure, whereas we
    show that with one-time preprocessing in almost cubic time, each subsequent query
    can be answered in at most linear time, and even the transitive closure can be
    computed in almost quartic time. Furthermore, we establish conditional optimality
    results showing that the worst-case running time of our algorithms cannot be improved
    without achieving major breakthroughs in graph algorithms (i.e., improving the
    worst-case bound for the shortest path problem in general graphs). Preliminary
    experimental results show that our algorithms perform favorably on several benchmarks.\r\n"

  text: 'We consider the stochastic shortest path (SSP)problem for succinct Markov
    decision processes(MDPs), where the MDP consists of a set of vari-ables, and a
    set of nondeterministic rules that up-date the variables. First, we show that
    several ex-amples from the AI literature can be modeled assuccinct MDPs.  Then
    we present computationalapproaches for upper and lower bounds for theSSP problem:
    (a) for computing upper bounds, ourmethod is polynomial-time in the implicit descrip-tion
    of the MDP; (b) for lower bounds, we present apolynomial-time (in the size of
    the implicit descrip-tion) reduction to quadratic programming. Our ap-proach is
    applicable even to infinite-state MDPs.Finally, we present experimental results
    to demon-strate the effectiveness of our approach on severalclassical examples
    from the AI literature.'

  text: 'Termination is one of the basic liveness properties, and we study the termination
    problem for probabilistic programs with real-valued variables. Previous works
    focused on the qualitative problem that asks whether an input program terminates
    with probability~1 (almost-sure termination). A powerful approach for this qualitative
    problem is the notion of ranking supermartingales with respect to a given set
    of invariants. The quantitative problem (probabilistic termination) asks for bounds
    on the termination probability. A fundamental and conceptual drawback of the existing
    approaches to address probabilistic termination is that even though the supermartingales
    consider the probabilistic behavior of the programs, the invariants are obtained
    completely ignoring the probabilistic aspect. In this work we address the probabilistic
    termination problem for linear-arithmetic probabilistic programs with nondeterminism.
    We define the notion of {\em stochastic invariants}, which are constraints along
    with a probability bound that the constraints hold. We introduce a concept of
    {\em repulsing supermartingales}. First, we show that repulsing supermartingales
    can be used to obtain bounds on the probability of the stochastic invariants.
    Second, we show the effectiveness of repulsing supermartingales in the following
    three ways: (1)~With a combination of ranking and repulsing supermartingales we
    can compute lower bounds on the probability of termination; (2)~repulsing supermartingales
    provide witnesses for refutation of almost-sure termination; and (3)~with a combination
    of ranking and repulsing supermartingales we can establish persistence properties
    of probabilistic programs. We also present results on related computational problems
    and an experimental evaluation of our approach on academic examples. '

  text: We study controller synthesis problems for finite-state Markov decision processes,
    where the objective is to optimize the expected mean-payoff performance and stability
    (also known as variability in the literature). We argue that the basic notion
    of expressing the stability using the statistical variance of the mean payoff
    is sometimes insufficient, and propose an alternative definition. We show that
    a strategy ensuring both the expected mean payoff and the variance below given
    bounds requires randomization and memory, under both the above definitions. We
    then show that the problem of finding such a strategy can be expressed as a set
    of constraints.

  text: "Transforming deterministic ω\r\n-automata into deterministic parity automata
    is traditionally done using variants of appearance records. We present a more
    efficient variant of this approach, tailored to Rabin automata, and several optimizations
    applicable to all appearance records. We compare the methods experimentally and
    find out that our method produces smaller automata than previous approaches. Moreover,
    the experiments demonstrate the potential of our method for LTL synthesis, using
    LTL-to-Rabin translators. It leads to significantly smaller parity automata when
    compared to state-of-the-art approaches on complex formulae."

  text: We consider the problem of computing the set of initial states of a dynamical
    system such that there exists a control strategy to ensure that the trajectories
    satisfy a temporal logic specification with probability 1 (almost-surely). We
    focus on discrete-time, stochastic linear dynamics and specifications given as
    formulas of the Generalized Reactivity(1) fragment of Linear Temporal Logic over
    linear predicates in the states of the system. We propose a solution based on
    iterative abstraction-refinement, and turn-based 2-player probabilistic games.
    While the theoretical guarantee of our algorithm after any finite number of iterations
    is only a partial solution, we show that if our algorithm terminates, then the
    result is the set of all satisfying initial states. Moreover, for any (partial)
    solution our algorithm synthesizes witness control strategies to ensure almost-sure
    satisfaction of the temporal logic specification. While the proposed algorithm
    guarantees progress and soundness in every iteration, it is computationally demanding.
    We offer an alternative, more efficient solution for the reachability properties
    that decomposes the problem into a series of smaller problems of the same type.
    All algorithms are demonstrated on an illustrative case study.

  text: 'The fixation probability is the probability that a new mutant introduced
    in a homogeneous population eventually takes over the entire population. The fixation
    probability is a fundamental quantity of natural selection, and known to depend
    on the population structure. Amplifiers of natural selection are population structures
    which increase the fixation probability of advantageous mutants, as compared to
    the baseline case of well-mixed populations. In this work we focus on symmetric
    population structures represented as undirected graphs. In the regime of undirected
    graphs, the strongest amplifier known has been the Star graph, and the existence
    of undirected graphs with stronger amplification properties has remained open
    for over a decade. In this work we present the Comet and Comet-swarm families
    of undirected graphs. We show that for a range of fitness values of the mutants,
    the Comet and Cometswarm graphs have fixation probability strictly larger than
    the fixation probability of the Star graph, for fixed population size and at the
    limit of large populations, respectively. '

  text: 'A fundamental algorithmic problem at the heart of static analysis is Dyck
    reachability. The input is a graphwhere the edges are labeled with different types
    of opening and closing parentheses, and the reachabilityinformation is computed
    via paths whose parentheses are properly matched. We present new results for Dyckreachability
    problems with applications to alias analysis and data-dependence analysis. Our
    main contributions,that include improved upper bounds as well as lower bounds
    that establish optimality guarantees, are asfollows:First, we consider Dyck reachability
    on bidirected graphs, which is the standard way of performing field-sensitive
    points-to analysis. Given a bidirected graph withnnodes andmedges, we present:
    (i) an algorithmwith worst-case running timeO(m+n·α(n)), whereα(n)is the inverse
    Ackermann function, improving thepreviously knownO(n2)time bound; (ii) a matching
    lower bound that shows that our algorithm is optimalwrt to worst-case complexity;
    and (iii) an optimal average-case upper bound ofO(m)time, improving thepreviously
    knownO(m·logn)bound.Second, we consider the problem of context-sensitive data-dependence
    analysis, where the task is to obtainanalysis summaries of library code in the
    presence of callbacks. Our algorithm preprocesses libraries in almostlinear time,
    after which the contribution of the library in the complexity of the client analysis
    is only linear,and only wrt the number of call sites.Third, we prove that combinatorial
    algorithms for Dyck reachability on general graphs with truly sub-cubic bounds
    cannot be obtained without obtaining sub-cubic combinatorial algorithms for Boolean
    MatrixMultiplication, which is a long-standing open problem. Thus we establish
    that the existing combinatorialalgorithms for Dyck reachability are (conditionally)
    optimal for general graphs. We also show that the samehardness holds for graphs
    of constant treewidth.Finally, we provide a prototype implementation of our algorithms
    for both alias analysis and data-dependenceanalysis. Our experimental evaluation
    demonstrates that the new algorithms significantly outperform allexisting methods
    on the two problems, over real-world benchmarks.'

  text: "We present a new dynamic partial-order reduction method for stateless model
    checking of concurrent programs. A common approach for exploring program behaviors
    relies on enumerating the traces of the program, without storing the visited states
    (aka stateless exploration). As the number of distinct traces grows exponentially,
    dynamic partial-order reduction (DPOR) techniques have been successfully used
    to partition the space of traces into equivalence classes (Mazurkiewicz partitioning),
    with the goal of exploring only few representative traces from each class.\r\nWe
    introduce a new equivalence on traces under sequential consistency semantics,
    which we call the observation equivalence. Two traces are observationally equivalent
    if every read event observes the same write event in both traces. While the traditional
    Mazurkiewicz equivalence is control-centric, our new definition is data-centric.
    We show that our observation equivalence is coarser than the Mazurkiewicz equivalence,
    and in many cases even exponentially coarser. We devise a DPOR exploration of
    the trace space, called data-centric DPOR, based on the observation equivalence.\r\n1.
    For acyclic architectures, our algorithm is guaranteed to explore exactly one
    representative trace from each observation class, while spending polynomial time
    per class. Hence, our algorithm is optimal wrt the observation equivalence, and
    in several cases explores exponentially fewer traces than any enumerative method
    based on the Mazurkiewicz equivalence.\r\n2. For cyclic architectures, we consider
    an equivalence between traces which is finer than the observation equivalence;
    but coarser than the Mazurkiewicz equivalence, and in some cases is exponentially
    coarser. Our data-centric DPOR algorithm remains optimal under this trace equivalence.
    \r\nFinally, we perform a basic experimental comparison between the existing Mazurkiewicz-based
    DPOR and our data-centric DPOR on a set of academic benchmarks. Our results show
    a significant reduction in both running time and the number of explored equivalence
    classes."

  text: 'Evolutionary graph theory studies the evolutionary dynamics in a population
    structure given as a connected graph. Each node of the graph represents an individual
    of the population, and edges determine how offspring are placed. We consider the
    classical birth-death Moran process where there are two types of individuals,
    namely, the residents with fitness 1 and mutants with fitness r. The fitness indicates
    the reproductive strength. The evolutionary dynamics happens as follows: in the
    initial step, in a population of all resident individuals a mutant is introduced,
    and then at each step, an individual is chosen proportional to the fitness of
    its type to reproduce, and the offspring replaces a neighbor uniformly at random.
    The process stops when all individuals are either residents or mutants. The probability
    that all individuals in the end are mutants is called the fixation probability,
    which is a key factor in the rate of evolution. We consider the problem of approximating
    the fixation probability. The class of algorithms that is extremely relevant for
    approximation of the fixation probabilities is the Monte-Carlo simulation of the
    process. Previous results present a polynomial-time Monte-Carlo algorithm for
    undirected graphs when r is given in unary. First, we present a simple modification:
    instead of simulating each step, we discard ineffective steps, where no node changes
    type (i.e., either residents replace residents, or mutants replace mutants). Using
    the above simple modification and our result that the number of effective steps
    is concentrated around the expected number of effective steps, we present faster
    polynomial-time Monte-Carlo algorithms for undirected graphs. Our algorithms are
    always at least a factor O(n2/ log n) faster as compared to the previous algorithms,
    where n is the number of nodes, and is polynomial even if r is given in binary.
    We also present lower bounds showing that the upper bound on the expected number
    of effective steps we present is asymptotically tight for undirected graphs. '

  text: 'Graph games provide the foundation for modeling and synthesis of reactive
    processes. Such games are played over graphs where the vertices are controlled
    by two adversarial players. We consider graph games where the objective of the
    first player is the conjunction of a qualitative objective (specified as a parity
    condition) and a quantitative objective (specified as a meanpayoff condition).
    There are two variants of the problem, namely, the threshold problem where the
    quantitative goal is to ensure that the mean-payoff value is above a threshold,
    and the value problem where the quantitative goal is to ensure the optimal mean-payoff
    value; in both cases ensuring the qualitative parity objective. The previous best-known
    algorithms for game graphs with n vertices, m edges, parity objectives with d
    priorities, and maximal absolute reward value W for mean-payoff objectives, are
    as follows: O(nd+1 . m . w) for the threshold problem, and O(nd+2 · m · W) for
    the value problem. Our main contributions are faster algorithms, and the running
    times of our algorithms are as follows: O(nd-1 · m ·W) for the threshold problem,
    and O(nd · m · W · log(n · W)) for the value problem. For mean-payoff parity objectives
    with two priorities, our algorithms match the best-known bounds of the algorithms
    for mean-payoff games (without conjunction with parity objectives). Our results
    are relevant in synthesis of reactive systems with both functional requirement
    (given as a qualitative objective) and performance requirement (given as a quantitative
    objective).'

  text: 'We consider two player, zero-sum, finite-state concurrent reachability games,
    played for an infinite number of rounds, where in every round, each player simultaneously
    and independently of the other players chooses an action, whereafter the successor
    state is determined by a probability distribution given by the current state and
    the chosen actions. Player 1 wins iff a designated goal state is eventually visited.
    We are interested in the complexity of stationary strategies measured by their
    patience, which is defined as the inverse of the smallest non-zero probability
    employed. Our main results are as follows: We show that: (i) the optimal bound
    on the patience of optimal and -optimal strategies, for both players is doubly
    exponential; and (ii) even in games with a single non-absorbing state exponential
    (in the number of actions) patience is necessary. '

  text: In the analysis of reactive systems a quantitative objective assigns a real
    value to every trace of the system. The value decision problem for a quantitative
    objective requires a trace whose value is at least a given threshold, and the
    exact value decision problem requires a trace whose value is exactly the threshold.
    We compare the computational complexity of the value and exact value decision
    problems for classical quantitative objectives, such as sum, discounted sum, energy,
    and mean-payoff for two standard models of reactive systems, namely, graphs and
    graph games.

  text: We consider the problem of developing automated techniques for solving recurrence
    relations to aid the expected-runtime analysis of programs. The motivation is
    that several classical textbook algorithms have quite efficient expected-runtime
    complexity, whereas the corresponding worst-case bounds are either inefficient
    (e.g., Quick-Sort), or completely ineffective (e.g., Coupon-Collector). Since
    the main focus of expected-runtime analysis is to obtain efficient bounds, we
    consider bounds that are either logarithmic, linear or almost-linear (O(log n),
    O(n), O(n · log n), respectively, where n represents the input size). Our main
    contribution is an efficient (simple linear-time algorithm) sound approach for
    deriving such expected-runtime bounds for the analysis of recurrence relations
    induced by randomized algorithms. The experimental results show that our approach
    can efficiently derive asymptotically optimal expected-runtime bounds for recurrences
    of classical randomized algorithms, including Randomized-Search, Quick-Sort, Quick-Select,
    Coupon-Collector, where the worst-case bounds are either inefficient (such as
    linear as compared to logarithmic expected-runtime complexity, or quadratic as
    compared to linear or almost-linear expected-runtime complexity), or ineffective.

  text: A standard objective in partially-observable Markov decision processes (POMDPs)
    is to find a policy that maximizes the expected discounted-sum payoff. However,
    such policies may still permit unlikely but highly undesirable outcomes, which
    is problematic especially in safety-critical applications. Recently, there has
    been a surge of interest in POMDPs where the goal is to maximize the probability
    to ensure that the payoff is at least a given threshold, but these approaches
    do not consider any optimization beyond satisfying this threshold constraint.
    In this work we go beyond both the “expectation” and “threshold” approaches and
    consider a “guaranteed payoff optimization (GPO)” problem for POMDPs, where we
    are given a threshold t and the objective is to find a policy σ such that a) each
    possible outcome of σ yields a discounted-sum payoff of at least t, and b) the
    expected discounted-sum payoff of σ is optimal (or near-optimal) among all policies
    satisfying a). We present a practical approach to tackle the GPO problem and evaluate
    it on standard POMDP benchmarks.
