text: We argue that the time is ripe to investigate differential monitoring, in
which the specification of a program's behavior is implicitly given by a second
program implementing the same informal specification. Similar ideas have been
proposed before, and are currently implemented in restricted form for testing
and specialized run-time analyses, aspects of which we combine. We discuss the
challenges of implementing differential monitoring as a general-purpose, black-box
run-time monitoring framework, and present promising results of a preliminary
implementation, showing low monitoring overheads for diverse programs.

text: "With the lithium-ion technology approaching its intrinsic limit with graphite-based
anodes, lithium metal is recently receiving renewed interest from the battery
community as potential high capacity anode for next-generation rechargeable batteries.
In this focus paper, we review the main advances in this field since the first
attempts in the\r\nmid-1970s. Strategies for enabling reversible cycling and avoiding
dendrite growth are thoroughly discussed, including specific applications in all-solid-state
(polymeric and inorganic), Lithium-sulphur and Li-O2 (air) batteries. A particular
attention is paid to review recent developments in regard of prototype manufacturing
and current state-ofthe-art of these battery technologies with respect to the
2030 targets of the EU Integrated Strategic Energy Technology Plan (SET-Plan)
Action 7."

text: "We consider the problem of expected cost analysis over nondeterministic probabilistic
programs, which aims at automated methods for analyzing the resource-usage of
such programs. Previous approaches for this problem could only handle nonnegative
bounded costs. However, in many scenarios, such as queuing networks or analysis
of cryptocurrency protocols, both positive and negative costs are necessary and
the costs are unbounded as well.\r\n\r\nIn this work, we present a sound and efficient
approach to obtain polynomial bounds on the expected accumulated cost of nondeterministic
probabilistic programs. Our approach can handle (a) general positive and negative
costs with bounded updates in variables; and (b) nonnegative costs with general
updates to variables. We show that several natural examples which could not be
handled by previous approaches are captured in our framework.\r\n\r\nMoreover,
our approach leads to an efficient polynomial-time algorithm, while no previous
approach for cost analysis of probabilistic programs could guarantee polynomial
runtime. Finally, we show the effectiveness of our approach by presenting experimental
results on a variety of programs, motivated by real-world applications, for which
we efficiently synthesize tight resource-usage bounds."

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: Synchronous programs are easy to specify because the side effects of an operation
are finished by the time the invocation of the operation returns to the caller.
Asynchronous programs, on the other hand, are difficult to specify because there
are side effects due to pending computation scheduled as a result of the invocation
of an operation. They are also difficult to verify because of the large number
of possible interleavings of concurrent asynchronous computation threads. We show
that specifications and correctness proofs for asynchronous programs can be structured
by introducing the fiction, for proof purposes, that intermediate, non-quiescent
states of asynchronous operations can be ignored. Then, the task of specification
becomes relatively simple and the task of verification can be naturally decomposed
into smaller sub-tasks. The sub-tasks iteratively summarize, guided by the structure
of an asynchronous program, the atomic effect of non-atomic operations and the
synchronous effect of asynchronous operations. This structuring of specifications
and proofs corresponds to the introduction of multiple layers of stepwise refinement
for asynchronous programs. We present the first proof rule, called synchronization,
to reduce asynchronous invocations on a lower layer to synchronous invocations
on a higher layer. We implemented our proof method in CIVL and evaluated it on
a collection of benchmark programs.

text: 'We consider the quantitative analysis problem for interprocedural control-flow
graphs (ICFGs). The input consists of an ICFG, a positive weight function that
assigns every transition a positive integer-valued number, and a labelling of
the transitions (events) as good, bad, and neutral events. The weight function
assigns to each transition a numerical value that represents ameasure of how good
or bad an event is. The quantitative analysis problem asks whether there is a
run of the ICFG where the ratio of the sum of the numerical weights of good events
versus the sum of weights of bad events in the long-run is at least a given threshold
(or equivalently, to compute the maximal ratio among all valid paths in the ICFG).
The quantitative analysis problem for ICFGs can be solved in polynomial time,
and we present an efficient and practical algorithm for the problem. We show that
several problems relevant for static program analysis, such as estimating the
worst-case execution time of a program or the average energy consumption of a
mobile application, can be modeled in our framework. We have implemented our algorithm
as a tool in the Java Soot framework. We demonstrate the effectiveness of our
approach with two case studies. First, we show that our framework provides a sound
approach (no false positives) for the analysis of inefficiently-used containers.
Second, we show that our approach can also be used for static profiling of programs
which reasons about methods that are frequently invoked. Our experimental results
show that our tool scales to relatively large benchmarks, and discovers relevant
and useful information that can be used to optimize performance of the programs. '

text: "We study the problem of developing efficient approaches for proving termination
of recursive programs with one-dimensional arrays. Ranking functions serve as
a sound and complete approach for proving termination of non-recursive programs
without array operations. First, we generalize ranking functions to the notion
of measure functions, and prove that measure functions (i) provide a sound method
to prove termination of recursive programs (with one-dimensional arrays), and
(ii) is both sound and complete over recursive programs without array operations.
Our second contribution is the synthesis of measure functions of specific forms
in polynomial time. More precisely, we prove that (i) polynomial measure functions
over recursive programs can be synthesized in polynomial time through Farkas’
Lemma and Handelman’s Theorem, and (ii) measure functions involving logarithm
and exponentiation can be synthesized in polynomial time through abstraction of
logarithmic or exponential terms and Handelman’s Theorem. A key application of
our method is the worst-case analysis of recursive programs. While previous methods
obtain worst-case polynomial bounds of the form O(n^k), where k is an integer,
our polynomial time methods can synthesize bounds of the form O(n log n), as well
as O(n^x), where x is not an integer. We show the applicability of our automated
technique to obtain worst-case complexity of classical recursive algorithms such
as (i) Merge-Sort, the divideand-\r\nconquer algorithm for the Closest-Pair problem,
where we obtain O(n log n) worst-case bound, and (ii) Karatsuba’s algorithm for
polynomial multiplication and Strassen’s algorithm for matrix multiplication,
where we obtain O(n^x) bound, where x is not an integer and close to the best-known
bounds for the respective algorithms. Finally, we present experimental results
to demonstrate the\r\neffectiveness of our approach."

text: "We consider the problem of developing automated techniques to aid the average-case
complexity analysis of programs. Several classical textbook algorithms have quite
efficient average-case complexity, whereas the corresponding worst-case bounds
are either inefficient (e.g., QUICK-SORT), or completely ineffective (e.g., COUPONCOLLECTOR).
Since the main focus of average-case analysis is to obtain efficient bounds, we
consider bounds that are either logarithmic,\r\nlinear, or almost-linear (O(log
n), O(n), O(n · log n),\r\nrespectively, where n represents the size of the input).
Our main contribution is a sound approach for deriving such average-case bounds
for randomized recursive programs. Our approach is efficient (a simple linear-time
algorithm), and it is based on (a) the analysis of recurrence relations induced
by randomized algorithms, and (b) a guess-and-check technique. Our approach can
infer the asymptotically optimal average-case bounds for classical randomized
algorithms, including RANDOMIZED-SEARCH, QUICKSORT, QUICK-SELECT, COUPON-COLLECTOR,
where the worstcase\r\nbounds are either inefficient (such as linear as compared
to logarithmic of average-case, or quadratic as compared to linear or almost-linear
of average-case), or ineffective. We have implemented our approach, and the experimental
results show that we obtain the bounds efficiently for various classical algorithms."

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: "The fixation probability is the probability that a new mutant introduced
in a homogeneous population eventually takes over the entire population.\r\nThe
fixation probability is a fundamental quantity of natural selection, and known
to depend on the population structure.\r\nAmplifiers 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.\r\nIn 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 Comet-swarm 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: "We consider Markov decision processes (MDPs) with multiple limit-average
(or mean-payoff) objectives. \r\nThere have been two different views: (i) the
expectation semantics, where the goal is to optimize the expected mean-payoff
objective, and (ii) the satisfaction semantics, where the goal is to maximize
the probability of runs such that the mean-payoff value stays above a given vector.
\ \r\nWe consider the problem where the goal is to optimize the expectation under
the constraint that the satisfaction semantics is ensured, and thus consider a
generalization that unifies the existing semantics.\r\nOur problem captures the
notion of optimization with respect to strategies that are risk-averse (i.e.,
ensures certain probabilistic guarantee).\r\nOur main results are algorithms for
the decision problem which are always polynomial in the size of the MDP. We also
show that an approximation of the Pareto-curve can be computed in time polynomial
in the size of the MDP, and the approximation factor, but exponential in the number
of dimensions.\r\nFinally, we present a complete characterization of the strategy
complexity (in terms of memory bounds and randomization) required to solve our
problem."

text: We consider the core algorithmic problems related to verification of systems
with respect to three classical quantitative properties, namely, the mean- payoff
property, the ratio property, and the minimum initial credit for energy property.
The algorithmic problem given a graph and a quantitative property asks to compute
the optimal value (the infimum value over all traces) from every node of the graph.
We consider graphs with constant treewidth, and it is well-known that the control-flow
graphs of most programs have constant treewidth. Let n denote the number of nodes
of a graph, m the number of edges (for constant treewidth graphs m = O ( n ) )
and W the largest absolute value of the weights. Our main theoretical results
are as follows. First, for constant treewidth graphs we present an algorithm that
approximates the mean-payoff value within a mul- tiplicative factor of ∊ in time
O ( n · log( n/∊ )) and linear space, as compared to the classical algorithms
that require quadratic time. Second, for the ratio property we present an algorithm
that for constant treewidth graphs works in time O ( n · log( | a · b · n | ))
= O ( n · log( n · W )) , when the output is a b , as compared to the previously
best known algorithm with running time O ( n 2 · log( n · W )) . Third, for the
minimum initial credit problem we show that (i) for general graphs the problem
can be solved in O ( n 2 · m ) time and the associated decision problem can be
solved in O ( n · m ) time, improving the previous known O ( n 3 · m · log( n
· W )) and O ( n 2 · m ) bounds, respectively; and (ii) for constant treewidth
graphs we present an algorithm that requires O ( n · log n ) time, improving the
previous known O ( n 4 · log( n · W )) bound. We have implemented some of our
algorithms and show that they present a significant speedup on standard benchmarks.

text: "We consider finite-state concurrent stochastic games, played by k>=2 players
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. We consider reachability objectives that given a target set
of states require that some state in the target set is visited, and the dual safety
objectives that given a target set require that only states in the target set
are 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.\r\n\r\n Our main results are as follows: We show that in two-player
zero-sum concurrent stochastic games (with reachability objective for one player
and the complementary safety objective for the other player): (i) the optimal
bound on the patience of optimal and epsilon-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. In general we study
the class of non-zero-sum games admitting epsilon-Nash equilibria. We show that
if there is at least one player with reachability objective, then doubly-exponential
patience is needed in general for epsilon-Nash equilibrium strategies, whereas
in contrast if all players have safety objectives, then the optimal bound on patience
for epsilon-Nash equilibrium strategies is only exponential."

text: "Evolution occurs in populations of reproducing individuals. The structure
of the population affects the outcome of the evolutionary process. Evolutionary
graph theory is a powerful approach to study this phenomenon. There are two graphs.
The interaction graph specifies who interacts with whom in the context of evolution.The
replacement graph specifies who competes with whom for reproduction. \r\nThe vertices
of the two graphs are the same, and each vertex corresponds to an individual of
the population. A key quantity is the fixation probability of a new mutant. It
is defined as the probability that a newly introduced mutant (on a single vertex)
generates a lineage of offspring which eventually takes over the entire population
of resident individuals. The basic computational questions are as follows: (i)
the qualitative question asks whether the fixation probability is positive; and
(ii) the quantitative approximation question asks for an approximation of the
fixation probability. \r\nOur main results are:\r\n(1) We show that the qualitative
question is NP-complete and the quantitative approximation question is #P-hard
in the special case when the interaction and the replacement graphs coincide and
even with the restriction that the resident individuals do not reproduce (which
corresponds to an invading population taking over an empty structure).\r\n(2)
We show that in general the qualitative question is PSPACE-complete and the quantitative
approximation question is PSPACE-hard and can be solved in exponential time.\r\n"

text: DEC-POMDPs extend POMDPs to a multi-agent setting, where several agents operate
in an uncertain environment independently to achieve a joint objective. DEC-POMDPs
have been studied with finite-horizon and infinite-horizon discounted-sum objectives,
and there exist solvers both for exact and approximate solutions. In this work
we consider Goal-DEC-POMDPs, where given a set of target states, the objective
is to ensure that the target set is reached with minimal cost. We consider the
indefinite-horizon (infinite-horizon with either discounted-sum, or undiscounted-sum,
where absorbing goal states have zero-cost) problem. We present a new method to
solve the problem that extends methods for finite-horizon DEC- POMDPs and the
RTDP-Bel approach for POMDPs. We present experimental results on several examples,
and show our approach presents promising results.

text: "We consider Markov decision processes (MDPs) with multiple limit-average
(or mean-payoff) objectives. \r\nThere have been two different views: (i) the
expectation semantics, where the goal is to optimize the expected mean-payoff
objective, and (ii) the satisfaction semantics, where the goal is to maximize
the probability of runs such that the mean-payoff value stays above a given vector.
\ \r\nWe consider the problem where the goal is to optimize the expectation under
the constraint that the satisfaction semantics is ensured, and thus consider a
generalization that unifies the existing semantics. Our problem captures the notion
of optimization with respect to strategies that are risk-averse (i.e., ensures
certain probabilistic guarantee).\r\nOur main results are algorithms for the decision
problem which are always polynomial in the size of the MDP.\r\nWe also show that
an approximation of the Pareto-curve can be computed in time polynomial in the
size of the MDP, and the approximation factor, but exponential in the number of
dimensions. Finally, we present a complete characterization of the strategy complexity
(in terms of memory bounds and randomization) required to solve our problem."
