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: "Smart contracts are programs that are stored and executed on the Blockchain
and can receive, manage and transfer money (cryptocurrency units). Two important
problems regarding smart contracts are formal analysis and compiler optimization.
Formal analysis is extremely important, because smart contracts hold funds worth
billions of dollars and their code is immutable after deployment. Hence, an undetected
bug can cause significant financial losses. Compiler optimization is also crucial,
because every action of a smart contract has to be executed by every node in the
Blockchain network. Therefore, optimizations in compiling smart contracts can
lead to significant savings in computation, time and energy.\r\n\r\nTwo classical
approaches in program analysis and compiler optimization are intraprocedural and
interprocedural analysis. In intraprocedural analysis, each function is analyzed
separately, while interprocedural analysis considers the entire program. In both
cases, the analyses are usually reduced to graph problems over the control flow
graph (CFG) of the program. These graph problems are often computationally expensive.
Hence, there has been ample research on exploiting structural properties of CFGs
for efficient algorithms. One such well-studied property is the treewidth, which
is a measure of tree-likeness of graphs. It is known that intraprocedural CFGs
of structured programs have treewidth at most 6, whereas the interprocedural treewidth
cannot be bounded. This result has been used as a basis for many efficient intraprocedural
analyses.\r\n\r\nIn this paper, we explore the idea of exploiting the treewidth
of smart contracts for formal analysis and compiler optimization. First, similar
to classical programs, we show that the intraprocedural treewidth of structured
Solidity and Vyper smart contracts is at most 9. Second, for global analysis,
we prove that the interprocedural treewidth of structured smart contracts is bounded
by 10 and, in sharp contrast with classical programs, treewidth-based algorithms
can be easily applied for interprocedural analysis. Finally, we supplement our
theoretical results with experiments using a tool we implemented for computing
treewidth of smart contracts and show that the treewidth is much lower in practice.
We use 36,764 real-world Ethereum smart contracts as benchmarks and find that
they have an average treewidth of at most 3.35 for the intraprocedural case and
3.65 for the interprocedural case.\r\n"

text: 'The verification of concurrent programs remains an open challenge, as thread
interaction has to be accounted for, which leads to state-space explosion. Stateless
model checking battles this problem by exploring traces rather than states of
the program. As there are exponentially many traces, dynamic partial-order reduction
(DPOR) techniques are used to partition the trace space into equivalence classes,
and explore a few representatives from each class. The standard equivalence that
underlies most DPOR techniques is the happens-before equivalence, however recent
works have spawned a vivid interest towards coarser equivalences. The efficiency
of such approaches is a product of two parameters: (i) the size of the partitioning
induced by the equivalence, and (ii) the time spent by the exploration algorithm
in each class of the partitioning. In this work, we present a new equivalence,
called value-happens-before and show that it has two appealing features. First,
value-happens-before is always at least as coarse as the happens-before equivalence,
and can be even exponentially coarser. Second, the value-happens-before partitioning
is efficiently explorable when the number of threads is bounded. We present an
algorithm called value-centric DPOR (VCDPOR), which explores the underlying partitioning
using polynomial time per class. Finally, we perform an experimental evaluation
of VCDPOR on various benchmarks, and compare it against other state-of-the-art
approaches. Our results show that value-happens-before typically induces a significant
reduction in the size of the underlying partitioning, which leads to a considerable
reduction in the running time for exploring the whole partitioning.'

text: 'Partially observable Markov decision processes (POMDPs) are the standard
models for planning under uncertainty with both finite and infinite horizon. Besides
the well-known discounted-sum objective, indefinite-horizon objective (aka Goal-POMDPs)
is another classical objective for POMDPs. In this case, given a set of target
states and a positive cost for each transition, the optimization objective is
to minimize the expected total cost until a target state is reached. In the literature,
RTDP-Bel or heuristic search value iteration (HSVI) have been used for solving
Goal-POMDPs. Neither of these algorithms has theoretical convergence guarantees,
and HSVI may even fail to terminate its trials. We give the following contributions:
(1) We discuss the challenges introduced in Goal-POMDPs and illustrate how they
prevent the original HSVI from converging. (2) We present a novel algorithm inspired
by HSVI, termed Goal-HSVI, and show that our algorithm has convergence guarantees.
(3) We show that Goal-HSVI outperforms RTDP-Bel on a set of well-known examples.'

text: People sometimes make their admirable deeds and accomplishments hard to spot,
such as by giving anonymously or avoiding bragging. Such ‘buried’ signals are
hard to reconcile with standard models of signalling or indirect reciprocity,
which motivate costly pro-social behaviour by reputational gains. To explain these
phenomena, we design a simple game theory model, which we call the signal-burying
game. This game has the feature that senders can bury their signal by deliberately
reducing the probability of the signal being observed. If the signal is observed,
however, it is identified as having been buried. We show under which conditions
buried signals can be maintained, using static equilibrium concepts and calculations
of the evolutionary dynamics. We apply our analysis to shed light on a number
of otherwise puzzling social phenomena, including modesty, anonymous donations,
subtlety in art and fashion, and overeagerness.

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

text: A model of computation that is widely used in the formal analysis of reactive
systems is symbolic algorithms. In this model the access to the input graph is
restricted to consist of symbolic operations, which are expensive in comparison
to the standard RAM operations. We give lower bounds on the number of symbolic
operations for basic graph problems such as the computation of the strongly connected
components and of the approximate diameter as well as for fundamental problems
in model checking such as safety, liveness, and coliveness. Our lower bounds are
linear in the number of vertices of the graph, even for constant-diameter graphs.
For none of these problems lower bounds on the number of symbolic operations were
known before. The lower bounds show an interesting separation of these problems
from the reachability problem, which can be solved with O(D) symbolic operations,
where D is the diameter of the graph. Additionally we present an approximation
algorithm for the graph diameter which requires Õ(n/D) symbolic steps to achieve
a (1 +ϵ)-approximation for any constant > 0. This compares to O(n/D) symbolic
steps for the (naive) exact algorithm and O(D) symbolic steps for a 2-approximation.
Finally we also give a refined analysis of the strongly connected components algorithms
of [15], showing that it uses an optimal number of symbolic steps that is proportional
to the sum of the diameters of the strongly connected components.

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: Probabilistic programs extend classical imperative programs with real-valued
random variables and random branching. The most basic liveness property for such
programs is the termination property. The qualitative (aka almost-sure) termination
problem asks whether a given program program terminates with probability 1. While
ranking functions provide a sound and complete method for non-probabilistic programs,
the extension of them to probabilistic programs is achieved via ranking supermartingales
(RSMs). Although deep theoretical results have been established about RSMs, their
application to probabilistic programs with nondeterminism has been limited only
to programs of restricted control-flow structure. For non-probabilistic programs,
lexicographic ranking functions provide a compositional and practical approach
for termination analysis of real-world programs. In this work we introduce lexicographic
RSMs and show that they present a sound method for almost-sure termination of
probabilistic programs with nondeterminism. We show that lexicographic RSMs provide
a tool for compositional reasoning about almost-sure termination, and for probabilistic
programs with linear arithmetic they can be synthesized efficiently (in polynomial
time). We also show that with additional restrictions even asymptotic bounds on
expected termination time can be obtained through lexicographic RSMs. Finally,
we present experimental results on benchmarks adapted from previous work to demonstrate
the effectiveness of our approach.

text: 'Solving parity games, which are equivalent to modal μ-calculus model checking,
is a central algorithmic problem in formal methods, with applications in reactive
synthesis, program repair, verification of branching-time properties, etc. Besides
the standard compu- tation model with the explicit representation of games, another
important theoretical model of computation is that of set-based symbolic algorithms.
Set-based symbolic algorithms use basic set operations and one-step predecessor
operations on the implicit description of games, rather than the explicit representation.
The significance of symbolic algorithms is that they provide scalable algorithms
for large finite-state systems, as well as for infinite-state systems with finite
quotient. Consider parity games on graphs with n vertices and parity conditions
with d priorities. While there is a rich literature of explicit algorithms for
parity games, the main results for set-based symbolic algorithms are as follows:
(a) the basic algorithm that requires O(nd) symbolic operations and O(d) symbolic
space; and (b) an improved algorithm that requires O(nd/3+1) symbolic operations
and O(n) symbolic space. In this work, our contributions are as follows: (1) We
present a black-box set-based symbolic algorithm based on the explicit progress
measure algorithm. Two important consequences of our algorithm are as follows:
(a) a set-based symbolic algorithm for parity games that requires quasi-polynomially
many symbolic operations and O(n) symbolic space; and (b) any future improvement
in progress measure based explicit algorithms immediately imply an efficiency
improvement in our set-based symbolic algorithm for parity games. (2) We present
a set-based symbolic algorithm that requires quasi-polynomially many symbolic
operations and O(d · log n) symbolic space. Moreover, for the important special
case of d ≤ log n, our algorithm requires only polynomially many symbolic operations
and poly-logarithmic symbolic space.'

text: 'Markov Decision Processes (MDPs) are a popular class of models suitable for
solving control decision problems in probabilistic reactive systems. We consider
parametric MDPs (pMDPs) that include parameters in some of the transition probabilities
to account for stochastic uncertainties of the environment such as noise or input
disturbances. We study pMDPs with reachability objectives where the parameter
values are unknown and impossible to measure directly during execution, but there
is a probability distribution known over the parameter values. We study for the
first time computing parameter-independent strategies that are expectation optimal,
i.e., optimize the expected reachability probability under the probability distribution
over the parameters. We present an encoding of our problem to partially observable
MDPs (POMDPs), i.e., a reduction of our problem to computing optimal strategies
in POMDPs. We evaluate our method experimentally on several benchmarks: a motivating
(repeated) learner model; a series of benchmarks of varying configurations of
a robot moving on a grid; and a consensus protocol.'

text: Responsiveness—the requirement that every request to a system be eventually
handled—is one of the fundamental liveness properties of a reactive system. Average
response time is a quantitative measure for the responsiveness requirement used
commonly in performance evaluation. We show how average response time can be computed
on state-transition graphs, on Markov chains, and on game graphs. In all three
cases, we give polynomial-time algorithms.

text: We consider a class of students learning a language from a teacher. The situation
can be interpreted as a group of child learners receiving input from the linguistic
environment. The teacher provides sample sentences. The students try to learn
the grammar from the teacher. In addition to just listening to the teacher, the
students can also communicate with each other. The students hold hypotheses about
the grammar and change them if they receive counter evidence. The process stops
when all students have converged to the correct grammar. We study how the time
to convergence depends on the structure of the classroom by introducing and evaluating
various complexity measures. We find that structured communication between students,
although potentially introducing confusion, can greatly reduce some of the complexity
measures. Our theory can also be interpreted as applying to the scientific process,
where nature is the teacher and the scientists are the students.

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: Partially-observable Markov decision processes (POMDPs) with discounted-sum
payoff are a standard framework to model a wide range of problems related to decision
making under uncertainty. Traditionally, the goal has been to obtain policies
that optimize the expectation of the discounted-sum payoff. A key drawback of
the expectation measure is that even low probability events with extreme payoff
can significantly affect the expectation, and thus the obtained policies are not
necessarily risk-averse. An alternate approach is to optimize the probability
that the payoff is above a certain threshold, which allows obtaining risk-averse
policies, but ignores optimization of the expectation. We consider the expectation
optimization with probabilistic guarantee (EOPG) problem, where the goal is to
optimize the expectation ensuring that the payoff is above a given threshold with
at least a specified probability. We present several results on the EOPG problem,
including the first algorithm to solve it.

text: 'This paper is devoted to automatic competitive analysis of real-time scheduling
algorithms for firm-deadline tasksets, where only completed tasks con- tribute
some utility to the system. Given such a taskset T , the competitive ratio of
an on-line scheduling algorithm A for T is the worst-case utility ratio of A over
the utility achieved by a clairvoyant algorithm. We leverage the theory of quantitative
graph games to address the competitive analysis and competitive synthesis problems.
For the competitive analysis case, given any taskset T and any finite-memory on-
line scheduling algorithm A , we show that the competitive ratio of A in T can
be computed in polynomial time in the size of the state space of A . Our approach
is flexible as it also provides ways to model meaningful constraints on the released
task sequences that determine the competitive ratio. We provide an experimental
study of many well-known on-line scheduling algorithms, which demonstrates the
feasibility of our competitive analysis approach that effectively replaces human
ingenuity (required Preliminary versions of this paper have appeared in Chatterjee

synthesis case, we are just given a taskset T , and the goal is to automatically
synthesize an opti- mal on-line scheduling algorithm A , i.e., one that guarantees
the largest competitive ratio possible for T . We show how the competitive synthesis
problem can be reduced to a two-player graph game with partial information, and
establish that the compu- tational complexity of solving this game is Np -complete.
The competitive synthesis problem is hence in Np in the size of the state space
of the non-deterministic labeled transition system encoding the taskset. Overall,
the proposed framework assists in the selection of suitable scheduling algorithms
for a given taskset, which is in fact the most common situation in real-time systems
design. '

text: We study the almost-sure termination problem for probabilistic programs. First,
we show that supermartingales with lower bounds on conditional absolute difference
provide a sound approach for the almost-sure termination problem. Moreover, using
this approach we can obtain explicit optimal bounds on tail probabilities of non-termination
within a given number of steps. Second, we present a new approach based on Central
Limit Theorem for the almost-sure termination problem, and show that this approach
can establish almost-sure termination of programs which none of the existing approaches
can handle. Finally, we discuss algorithmic approaches for the two above methods
that lead to automated analysis techniques for almost-sure termination of probabilistic
programs.

text: 'Because of the intrinsic randomness of the evolutionary process, a mutant
with a fitness advantage has some chance to be selected but no certainty. Any
experiment that searches for advantageous mutants will lose many of them due to
random drift. It is therefore of great interest to find population structures
that improve the odds of advantageous mutants. Such structures are called amplifiers
of natural selection: they increase the probability that advantageous mutants
are selected. Arbitrarily strong amplifiers guarantee the selection of advantageous
mutants, even for very small fitness advantage. Despite intensive research over
the past decade, arbitrarily strong amplifiers have remained rare. Here we show
how to construct a large variety of them. Our amplifiers are so simple that they
could be useful in biotechnology, when optimizing biological molecules, or as
a diagnostic tool, when searching for faster dividing cells or viruses. They could
also occur in natural population structures.'

text: Graph-based games are an important tool in computer science. They have applications
in synthesis, verification, refinement, and far beyond. We review graphbased games
with objectives on infinite plays. We give definitions and algorithms to solve
the games and to give a winning strategy. The objectives we consider are mostly
Boolean, but we also look at quantitative graph-based games and their objectives.
Synthesis aims to turn temporal logic specifications into correct reactive systems.
We explain the reduction of synthesis to graph-based games (or equivalently tree
automata) using synthesis of LTL specifications as an example. We treat the classical
approach that uses determinization of parity automata and more modern approaches.

text: "The Big Match is a multi-stage two-player game. In each stage Player 1 hides
one or two pebbles in his hand, and his opponent has to guess that number; Player
1 loses a point if Player 2 is correct, and otherwise he wins a point. As soon
as Player 1 hides one pebble, the players cannot change their choices in any future
stage.\r\nBlackwell and Ferguson (1968) give an ε-optimal strategy for Player
1 that hides, in each stage, one pebble with a probability that depends on the
entire past history. Any strategy that depends just on the clock or on a finite
memory is worthless. The long-standing natural open problem has been whether every
strategy that depends just on the clock and a finite memory is worthless. We prove
that there is such a strategy that is ε-optimal. In fact, we show that just two
states of memory are sufficient.\r\n"
