  text: "In this note, we introduce a distributed twist on the classic coupon collector
    problem: a set of m collectors wish to each obtain a set of n coupons; for this,
    they can each sample coupons uniformly at random, but can also meet in pairwise
    interactions, during which they can exchange coupons. By doing so, they hope to
    reduce the number of coupons that must be sampled by each collector in order to
    obtain a full set. This extension is natural when considering real-world manifestations
    of the coupon collector phenomenon, and has been remarked upon and studied empirically
    (Hayes and Hannigan 2006, Ahmad et al. 2014, Delmarcelle 2019).\r\n\r\nWe provide
    the first theoretical analysis for such a scenario. We find that “coupon collecting
    with friends” can indeed significantly reduce the number of coupons each collector
    must sample, and raises interesting connections to the more traditional variants
    of the problem. While our analysis is in most cases asymptotically tight, there
    are several open questions raised, regarding finer-grained analysis of both “coupon
    collecting with friends,” and of a long-studied variant of the original problem
    in which a collector requires multiple full sets of coupons."

  text: 'Stateless model checking (SMC) is one of the standard approaches to the verification
    of concurrent programs. As scheduling non-determinism creates exponentially large
    spaces of thread interleavings, SMC attempts to partition this space into equivalence
    classes and explore only a few representatives from each class. The efficiency
    of this approach depends on two factors: (a) the coarseness of the partitioning,
    and (b) the time to generate representatives in each class. For this reason, the
    search for coarse partitionings that are efficiently explorable is an active research
    challenge. In this work we present   RVF-SMC , a new SMC algorithm that uses a
    novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are
    deemed equivalent if they agree on the value obtained in each read event, and
    read events induce consistent causal orderings between them. The RVF partitioning
    is provably coarser than recent approaches based on Mazurkiewicz and “reads-from”
    partitionings. Our experimental evaluation reveals that RVF is quite often a very
    effective equivalence, as the underlying partitioning is exponentially coarser
    than other approaches. Moreover,   RVF-SMC  generates representatives very efficiently,
    as the reduction in the partitioning is often met with significant speed-ups in
    the model checking task.'

  text: "Classic dynamic data structure problems maintain a data structure subject
    to a sequence S of updates and they answer queries using the latest version of
    the data structure, i.e., the data structure after processing the whole sequence.
    To handle operations that change the sequence S of updates, Demaine et al. [7]
    introduced retroactive data structures (RDS). A retroactive operation modifies
    the update sequence S in a given position t, called time, and either creates or
    cancels an update in S at time t. A fully retroactive data structure supports
    queries at any time t: a query at time t is answered using only the updates of
    S up to time t. While efficient RDS have been proposed for classic data structures,
    e.g., stack, priority queue and binary search tree, the retroactive version of
    graph problems are rarely studied.\r\n\r\nIn this paper we study retroactive graph
    problems including connectivity, minimum spanning forest (MSF), maximum degree,
    etc. We show that under the OMv conjecture (proposed by Henzinger et al. [15]),
    there does not exist fully RDS maintaining connectivity or MSF, or incremental
    fully RDS maintaining the maximum degree with \U0001D442(\U0001D45B1−\U0001D716)
    time per operation, for any constant \U0001D716>0. Furthermore, We provide RDS
    with almost tight time per operation. We give fully RDS for maintaining the maximum
    degree, connectivity and MSF in \U0001D442̃ (\U0001D45B) time per operation. We
    also give an algorithm for the incremental (insertion-only) fully retroactive
    connectivity with \U0001D442̃ (1) time per operation, showing that the lower bound
    cannot be extended to this setting.\r\n\r\nWe also study a restricted version
    of RDS, where the only change to S is the swap of neighboring updates and show
    that for this problem we can beat the above hardness result. This also implies
    the first non-trivial dynamic Reeb graph computation algorithm."

  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: Discrete-time Markov Chains (MCs) and Markov Decision Processes (MDPs) are
    two standard formalisms in system analysis. Their main associated quantitative
    objectives are hitting probabilities, discounted sum, and mean payoff. Although
    there are many techniques for computing these objectives in general MCs/MDPs,
    they have not been thoroughly studied in terms of parameterized algorithms, particularly
    when treewidth is used as the parameter. This is in sharp contrast to qualitative
    objectives for MCs, MDPs and graph games, for which treewidth-based algorithms
    yield significant complexity improvements. In this work, we show that treewidth
    can also be used to obtain faster algorithms for the quantitative problems. For
    an MC with n states and m transitions, we show that each of the classical quantitative
    objectives can be computed in   O((n+m)⋅t2)  time, given a tree decomposition
    of the MC with width t. Our results also imply a bound of   O(κ⋅(n+m)⋅t2)  for
    each objective on MDPs, where   κ  is the number of strategy-iteration refinements
    required for the given input and objective. Finally, we make an experimental evaluation
    of our new algorithms on low-treewidth MCs and MDPs obtained from the DaCapo benchmark
    suite. Our experiments show that on low-treewidth MCs and MDPs, our algorithms
    outperform existing well-established methods by one or more orders of magnitude.

  text: 'A simple drawing D(G) of a graph G is one where each pair of edges share
    at most one point: either a common endpoint or a proper crossing. An edge e in
    the complement of G can be inserted into D(G) if there exists a simple drawing
    of   G+e  extending D(G). As a result of Levi’s Enlargement Lemma, if a drawing
    is rectilinear (pseudolinear), that is, the edges can be extended into an arrangement
    of lines (pseudolines), then any edge in the complement of G can be inserted.
    In contrast, we show that it is   NP -complete to decide whether one edge can
    be inserted into a simple drawing. This remains true even if we assume that the
    drawing is pseudocircular, that is, the edges can be extended to an arrangement
    of pseudocircles. On the positive side, we show that, given an arrangement of
    pseudocircles   A  and a pseudosegment   σ , it can be decided in polynomial time
    whether there exists a pseudocircle   Φσ  extending   σ  for which   A∪{Φσ}  is
    again an arrangement of pseudocircles.'

  text: We call a multigraph non-homotopic if it can be drawn in the plane in such
    a way that no two edges connecting the same pair of vertices can be continuously
    transformed into each other without passing through a vertex, and no loop can
    be shrunk to its end-vertex in the same way. It is easy to see that a non-homotopic
    multigraph on   n>1  vertices can have arbitrarily many edges. We prove that the
    number of crossings between the edges of a non-homotopic multigraph with n vertices
    and   m>4n  edges is larger than   cm2n  for some constant   c>0 , and that this
    bound is tight up to a polylogarithmic factor. We also show that the lower bound
    is not asymptotically sharp as n is fixed and   m⟶∞ .

  text: "For 1≤m≤n, we consider a natural m-out-of-n multi-instance scenario for a
    public-key encryption (PKE) scheme. An adversary, given n independent instances
    of PKE, wins if he breaks at least m out of the n instances. In this work, we
    are interested in the scaling factor of PKE schemes, SF, which measures how well
    the difficulty of breaking m out of the n instances scales in m. That is, a scaling
    factor SF=ℓ indicates that breaking m out of n instances is at least ℓ times more
    difficult than breaking one single instance. A PKE scheme with small scaling factor
    hence provides an ideal target for mass surveillance. In fact, the Logjam attack
    (CCS 2015) implicitly exploited, among other things, an almost constant scaling
    factor of ElGamal over finite fields (with shared group parameters).\r\n\r\nFor
    Hashed ElGamal over elliptic curves, we use the generic group model to argue that
    the scaling factor depends on the scheme's granularity. In low granularity, meaning
    each public key contains its independent group parameter, the scheme has optimal
    scaling factor SF=m; In medium and high granularity, meaning all public keys share
    the same group parameter, the scheme still has a reasonable scaling factor SF=√m.
    Our findings underline that instantiating ElGamal over elliptic curves should
    be preferred to finite fields in a multi-instance scenario.\r\n\r\nAs our main
    technical contribution, we derive new generic-group lower bounds of Ω(√(mp)) on
    the difficulty of solving both the m-out-of-n Gap Discrete Logarithm and the m-out-of-n
    Gap Computational Diffie-Hellman problem over groups of prime order p, extending
    a recent result by Yun (EUROCRYPT 2015). We establish the lower bound by studying
    the hardness of a related computational problem which we call the search-by-hypersurface
    problem."

  text: "We introduce the notion of Witness Maps as a cryptographic notion of a proof
    system. A Unique Witness Map (UWM) deterministically maps all witnesses for an
    \  NP  statement to a single representative witness, resulting in a computationally
    sound, deterministic-prover, non-interactive witness independent proof system.
    A relaxation of UWM, called Compact Witness Map (CWM), maps all the witnesses
    to a small number of witnesses, resulting in a “lossy” deterministic-prover, non-interactive
    proof-system. We also define a Dual Mode Witness Map (DMWM) which adds an “extractable”
    mode to a CWM.\r\nOur main construction is a DMWM for all   NP  relations, assuming
    sub-exponentially secure indistinguishability obfuscation (  iO ), along with
    standard cryptographic assumptions. The DMWM construction relies on a CWM and
    a new primitive called Cumulative All-Lossy-But-One Trapdoor Functions (C-ALBO-TDF),
    both of which are in turn instantiated based on   iO  and other primitives. Our
    instantiation of a CWM is in fact a UWM; in turn, we show that a UWM implies Witness
    Encryption. Along the way to constructing UWM and C-ALBO-TDF, we also construct,
    from standard assumptions, Puncturable Digital Signatures and a new primitive
    called Cumulative Lossy Trapdoor Functions (C-LTDF). The former improves up on
    a construction of Bellare et al. (Eurocrypt 2016), who relied on sub-exponentially
    secure   iO  and sub-exponentially secure OWF.\r\nAs an application of our constructions,
    we show how to use a DMWM to construct the first leakage and tamper-resilient
    signatures with a deterministic signer, thereby solving a decade old open problem
    posed by Katz and Vaikunthanathan (Asiacrypt 2009), by Boyle, Segev and Wichs
    (Eurocrypt 2011), as well as by Faonio and Venturi (Asiacrypt 2016). Our construction
    achieves the optimal leakage rate of   1−o(1) ."

  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: "Traditional concurrent programming involves manipulating shared mutable state.
    Alternatives to this programming style are communicating sequential processes
    (CSP) and actor models, which share data via explicit communication. These models
    have been known for almost half a century, and have recently had started to gain
    significant traction among modern programming languages. The common abstraction
    for communication between several processes is the channel. Although channels
    are similar to producer-consumer data structures, they have different semantics
    and support additional operations, such as the select expression. Despite their
    growing popularity, most known implementations of channels use lock-based data
    structures and can be rather inefficient.\r\n\r\nIn this paper, we present the
    first efficient lock-free algorithm for implementing a communication channel for
    CSP programming. We provide implementations and experimental results in the Kotlin
    and Go programming languages. Our new algorithm outperforms existing implementations
    on many workloads, while providing non-blocking progress guarantee. Our design
    can serve as an example of how to construct general communication data structures
    for CSP and actor models. "

  text: Simple drawings of graphs are those in which each pair of edges share at most
    one point, either a common endpoint or a proper crossing. In this paper we study
    the problem of extending a simple drawing D(G) of a graph G by inserting a set
    of edges from the complement of G into D(G) such that the result is a simple drawing.
    In the context of rectilinear drawings, the problem is trivial. For pseudolinear
    drawings, the existence of such an extension follows from Levi’s enlargement lemma.
    In contrast, we prove that deciding if a given set of edges can be inserted into
    a simple drawing is NP-complete. Moreover, we show that the maximization version
    of the problem is APX-hard. We also present a polynomial-time algorithm for deciding
    whether one edge uv can be inserted into D(G) when {u,v} is a dominating set for
    the graph G.

  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: "Proofs of sequential work (PoSW) are proof systems where a prover, upon receiving
    a statement χ and a time parameter T computes a proof ϕ(χ,T) which is efficiently
    and publicly verifiable. The proof can be computed in T sequential steps, but
    not much less, even by a malicious party having large parallelism. A PoSW thus
    serves as a proof that T units of time have passed since χ\r\n\r\nwas received.\r\n\r\nPoSW
    were introduced by Mahmoody, Moran and Vadhan [MMV11], a simple and practical
    construction was only recently proposed by Cohen and Pietrzak [CP18].\r\n\r\nIn
    this work we construct a new simple PoSW in the random permutation model which
    is almost as simple and efficient as [CP18] but conceptually very different. Whereas
    the structure underlying [CP18] is a hash tree, our construction is based on skip
    lists and has the interesting property that computing the PoSW is a reversible
    computation.\r\nThe fact that the construction is reversible can potentially be
    used for new applications like constructing proofs of replication. We also show
    how to “embed” the sloth function of Lenstra and Weselowski [LW17] into our PoSW
    to get a PoSW where one additionally can verify correctness of the output much
    more efficiently than recomputing it (though recent constructions of “verifiable
    delay functions” subsume most of the applications this construction was aiming
    at)."

  text: 'Computer vision systems for automatic image categorization have become accurate
    and reliable enough that they can run continuously for days or even years as components
    of real-world commercial applications. A major open problem in this context, however,
    is quality control. Good classification performance can only be expected if systems
    run under the specific conditions, in particular data distributions, that they
    were trained for. Surprisingly, none of the currently used deep network architectures
    have a built-in functionality that could detect if a network operates on data
    from a distribution it was not trained for, such that potentially a warning to
    the human users could be triggered. In this work, we describe KS(conf), a procedure
    for detecting such outside of specifications (out-of-specs) operation, based on
    statistical testing of the network outputs. We show by extensive experiments using
    the ImageNet, AwA2 and DAVIS datasets on a variety of ConvNets architectures that
    KS(conf) reliably detects out-of-specs situations. It furthermore has a number
    of properties that make it a promising candidate for practical deployment: it
    is easy to implement, adds almost no overhead to the system, works with all networks,
    including pretrained ones, and requires no a priori knowledge of how the data
    distribution could change. '

  text: "Bitcoin has become the most successful cryptocurrency ever deployed, and
    its most distinctive feature is that it is decentralized. Its underlying protocol
    (Nakamoto consensus) achieves this by using proof of work, which has the drawback
    that it causes the consumption of vast amounts of energy to maintain the ledger.
    Moreover, Bitcoin mining dynamics have become less distributed over time.\r\n\r\nTowards
    addressing these issues, we propose SpaceMint, a cryptocurrency based on proofs
    of space instead of proofs of work. Miners in SpaceMint dedicate disk space rather
    than computation. We argue that SpaceMint’s design solves or alleviates several
    of Bitcoin’s issues: most notably, its large energy consumption. SpaceMint also
    rewards smaller miners fairly according to their contribution to the network,
    thus incentivizing more distributed participation.\r\n\r\nThis paper adapts proof
    of space to enable its use in cryptocurrency, studies the attacks that can arise
    against a Bitcoin-like blockchain that uses proof of space, and proposes a new
    blockchain format and transaction types to address these attacks. Our prototype
    shows that initializing 1 TB for mining takes about a day (a one-off setup cost),
    and miners spend on average just a fraction of a second per block mined. Finally,
    we provide a game-theoretic analysis modeling SpaceMint as an extensive game (the
    canonical game-theoretic notion for games that take place over time) and show
    that this stylized game satisfies a strong equilibrium notion, thereby arguing
    for SpaceMint ’s stability and consensus."

  text: In this paper, we propose an algorithm to build discrete spherical shell having
    integer center and real-valued inner and outer radii on the face-centered cubic
    (FCC) grid. We address the problem by mapping it to a 2D scenario and building
    the shell layer by layer on hexagonal grids with additive manufacturing in mind.
    The layered hexagonal grids get shifted according to need as we move from one
    layer to another and forms the FCC grid in 3D. However, we restrict our computation
    strictly to 2D in order to utilize symmetry and simplicity.

  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."
