text: We consider two-player partial-observation stochastic games on finitestate
graphs where player 1 has partial observation and player 2 has perfect observation.
The winning condition we study are ε-regular conditions specified as parity objectives.
The qualitative-analysis problem given a partial-observation stochastic game and
a parity objective asks whether there is a strategy to ensure that the objective
is satisfied with probability 1 (resp. positive probability). These qualitative-analysis
problems are known to be undecidable. However in many applications the relevant
question is the existence of finite-memory strategies, and the qualitative-analysis
problems under finite-memory strategies was recently shown to be decidable in
2EXPTIME.We improve the complexity and show that the qualitative-analysis problems
for partial-observation stochastic parity games under finite-memory strategies
are EXPTIME-complete; and also establish optimal (exponential) memory bounds for
finite-memory strategies required for qualitative analysis.

text: 'The theory of graph games is the foundation for modeling and synthesizing
reactive processes. In the synthesis of stochastic processes, we use 2 1/2-player
games where some transitions of the game graph are controlled by two adversarial
players, the System and the Environment, and the other transitions are determined
probabilistically. We consider 2 1/2-player games where the objective of the System
is the conjunction of a qualitative objective (specified as a parity condition)
and a quantitative objective (specified as a mean-payoff condition). We establish
that the problem of deciding whether the System can ensure that the probability
to satisfy the mean-payoff parity objective is at least a given threshold is in
NP ∩ coNP, matching the best known bound in the special case of 2-player games
(where all transitions are deterministic). We present an algorithm running in
time O(d·n2d·MeanGame) to compute the set of almost-sure winning states from which
the objective can be ensured with probability 1, where n is the number of states
of the game, d the number of priorities of the parity objective, and MeanGame
is the complexity to compute the set of almost-sure winning states in 2 1/2-player
mean-payoff games. Our results are useful in the synthesis of stochastic reactive
systems with both functional requirement (given as a qualitative objective) and
performance requirement (given as a quantitative objective). '

text: The edit distance between two (untimed) traces is the minimum cost of a sequence
of edit operations (insertion, deletion, or substitution) needed to transform
one trace to the other. Edit distances have been extensively studied in the untimed
setting, and form the basis for approximate matching of sequences in different
domains such as coding theory, parsing, and speech recognition. In this paper,
we lift the study of edit distances from untimed languages to the timed setting.
We define an edit distance between timed words which incorporates both the edit
distance between the untimed words and the absolute difference in time stamps.
Our edit distance between two timed words is computable in polynomial time. Further,
we show that the edit distance between a timed word and a timed language generated
by a timed automaton, defined as the edit distance between the word and the closest
word in the language, is PSPACE-complete. While computing the edit distance between
two timed automata is undecidable, we show that the approximate version, where
we decide if the edit distance between two timed automata is either less than
a given parameter or more than δ away from the parameter, for δ > 0, can be
solved in exponential space and is EXPSPACE-hard. Our definitions and techniques
can be generalized to the setting of hybrid systems, and analogous decidability
results hold for rectangular automata.

text: "Model-based testing is a promising technology for black-box software and
hardware testing, in which test cases are generated automatically from high-level
specifications. Nowadays, systems typically consist of multiple interacting components
and, due to their complexity, testing presents a considerable portion of the effort
and cost in the design process. Exploiting the compositional structure of system
specifications can considerably reduce the effort in model-based testing. Moreover,
inferring properties about the system from testing its individual components allows
the designer to reduce the amount of integration testing.\r\nIn this paper, we
study compositional properties of the IOCO-testing theory. We propose a new approach
to composition and hiding operations, inspired by contract-based design and interface
theories. These operations preserve behaviors that are compatible under composition
and hiding, and prune away incompatible ones. The resulting specification characterizes
the input sequences for which the unit testing of components is sufficient to
infer the correctness of component integration without the need for further tests.
We provide a methodology that uses these results to minimize integration testing
effort, but also to detect potential weaknesses in specifications. While we focus
on asynchronous models and the IOCO conformance relation, the resulting methodology
can be applied to a broader class of systems."

text: "We consider Markov decision processes (MDPs) which are a standard model for
probabilistic systems. We focus on qualitative properties for MDPs that can express
that desired behaviors of the system arise almost-surely (with probability 1)
or with positive probability.\r\nWe introduce a new simulation relation to capture
the refinement relation of MDPs with respect to qualitative properties, and present
discrete graph theoretic algorithms with quadratic complexity to compute the simulation
relation.\r\nWe present an automated technique for assume-guarantee style reasoning
for compositional analysis of MDPs with qualitative properties by giving a counter-example
guided abstraction-refinement approach to compute our new simulation relation.
We have implemented our algorithms and show that the compositional analysis leads
to significant improvements. "

text: We consider multi-player graph games with partial-observation and parity objective.
While the decision problem for three-player games with a coalition of the first
and second players against the third player is undecidable in general, we present
a decidability result for partial-observation games where the first and third
player are in a coalition against the second player, thus where the second player
is adversarial but weaker due to partial-observation. We establish tight complexity
bounds in the case where player 1 is less informed than player 2, namely 2-EXPTIME-completeness
for parity objectives. The symmetric case of player 1 more informed than player
2 is much more complicated, and we show that already in the case where player
1 has perfect observation, memory of size non-elementary is necessary in general
for reachability objectives, and the problem is decidable for safety and reachability
objectives. From our results we derive new complexity results for partial-observation
stochastic games.

text: "We consider the reachability and shortest path problems on low tree-width
graphs, with n nodes, m edges, and tree-width t, on a standard RAM with wordsize
W. We use O to hide polynomial factors of the inverse of the Ackermann function.
Our main contributions are three fold:\r\n1. For reachability, we present an algorithm
that requires O(n·t2·log(n/t)) preprocessing time, O(n·(t·log(n/t))/W) space,
and O(t/W) time for pair queries and O((n·t)/W) time for single-source queries.
Note that for constant t our algorithm uses O(n·logn) time for preprocessing;
and O(n/W) time for single-source queries, which is faster than depth first search/breath
first search (after the preprocessing).\r\n2. We present an algorithm for shortest
path that requires O(n·t2) preprocessing time, O(n·t) space, and O(t2) time for
pair queries and O(n·t) time single-source queries.\r\n3. We give a space versus
query time trade-off algorithm for shortest path that, given any constant >0,
requires O(n·t2) preprocessing time, O(n·t2) space, and O(n1−·t2) time for pair
queries.\r\nOur algorithms improve all existing results, and use very simple data
structures."

text: "As hybrid systems involve continuous behaviors, they should be evaluated
by quantitative methods, rather than qualitative methods. In this paper we adapt
a quantitative framework, called model measuring, to the hybrid systems domain.
The model-measuring problem asks, given a model M and a specification, what is
the maximal distance such that all models within that distance from M satisfy
(or violate) the specification. A distance function on models is given as part
of the input of the problem. Distances, especially related to continuous behaviors
are more natural in the hybrid case than the discrete case. We are interested
in distances represented by monotonic hybrid automata, a hybrid counterpart of
(discrete) weighted automata, whose recognized timed languages are monotone (w.r.t.
inclusion) in the values of parameters.\r\n\r\nThe contributions of this paper
are twofold. First, we give sufficient conditions under which the model-measuring
problem can be solved. Second, we discuss the modeling of distances and applications
of the model-measuring problem."

text: "We define the model-measuring problem: given a model M and specification
φ, what is the maximal distance ρ such that all models M'within distance ρ from
M satisfy (or violate)φ. The model measuring problem presupposes a distance function
on models. We concentrate on automatic distance functions, which are defined by
weighted automata.\r\nThe model-measuring problem subsumes several generalizations
of the classical model-checking problem, in particular, quantitative model-checking
problems that measure the degree of satisfaction of a specification, and robustness
problems that measure how much a model can be perturbed without violating the
specification.\r\nWe show that for automatic distance functions, and ω-regular
linear-time and branching-time specifications, the model-measuring problem can
be solved.\r\nWe use automata-theoretic model-checking methods for model measuring,
replacing the emptiness question for standard word and tree automata by the optimal-weight
question for the weighted versions of these automata. We consider weighted automata
that accumulate weights by maximizing, summing, discounting, and limit averaging.
\r\nWe give several examples of using the model-measuring problem to compute various
notions of robustness and quantitative satisfaction for temporal specifications."

text: As hybrid systems involve continuous behaviors, they should be evaluated by
quantitative methods, rather than qualitative methods. In this paper we adapt
a quantitative framework, called model measuring, to the hybrid systems domain.
The model-measuring problem asks, given a model M and a specification, what is
the maximal distance such that all models within that distance from M satisfy
(or violate) the specification. A distance function on models is given as part
of the input of the problem. Distances, especially related to continuous behaviors
are more natural in the hybrid case than the discrete case. We are interested
in distances represented by monotonic hybrid automata, a hybrid counterpart of
(discrete) weighted automata, whose recognized timed languages are monotone (w.r.t.
inclusion) in the values of parameters.The contributions of this paper are twofold.
First, we give sufficient conditions under which the model-measuring problem can
be solved. Second, we discuss the modeling of distances and applications of the
model-measuring problem.

text: We consider multi-player graph games with partial-observation and parity objective.
While the decision problem for three-player games with a coalition of the first
and second players against the third player is undecidable, we present a decidability
result for partial-observation games where the first and third player are in a
coalition against the second player, thus where the second player is adversarial
but weaker due to partial-observation. We establish tight complexity bounds in
the case where player 1 is less informed than player 2, namely 2-EXPTIME-completeness
for parity objectives. The symmetric case of player 1 more informed than player
2 is much more complicated, and we show that already in the case where player
1 has perfect observation, memory of size non-elementary is necessary in general
for reachability objectives, and the problem is decidable for safety and reachability
objectives. Our results have tight connections with partial-observation stochastic
games for which we derive new complexity results.

text: 'We consider concurrent mean-payoff games, a very well-studied class of two-player
(player 1 vs player 2) zero-sum games on finite-state graphs where every transition
is assigned a reward between 0 and 1, and the payoff function is the long-run
average of the rewards. The value is the maximal expected payoff that player 1
can guarantee against all strategies of player 2. We consider the computation
of the set of states with value 1 under finite-memory strategies for player 1,
and our main results for the problem are as follows: (1) we present a polynomial-time
algorithm; (2) we show that whenever there is a finite-memory strategy, there
is a stationary strategy that does not need memory at all; and (3) we present
an optimal bound (which is double exponential) on the patience of stationary strategies
(where patience of a distribution is the inverse of the smallest positive probability
and represents a complexity measure of a stationary strategy).'

text: We consider partially observable Markov decision processes (POMDPs), that
are a standard framework for robotics applications to model uncertainties present
in the real world, with temporal logic specifications. All temporal logic specifications
in linear-time temporal logic (LTL) can be expressed as parity objectives. We
study the qualitative analysis problem for POMDPs with parity objectives that
asks whether there is a controller (policy) to ensure that the objective holds
with probability 1 (almost-surely). While the qualitative analysis of POMDPs with
parity objectives is undecidable, recent results show that when restricted to
finite-memory policies the problem is EXPTIME-complete. While the problem is intractable
in theory, we present a practical approach to solve the qualitative analysis problem.
We designed several heuristics to deal with the exponential complexity, and have
used our implementation on a number of well-known POMDP examples for robotics
applications. Our results provide the first practical approach to solve the qualitative
analysis of robot motion planning with LTL properties in the presence of uncertainty.

in linear-time temporal logic (LTL) can be expressed as parity objectives. We
study the qualitative analysis problem for POMDPs with parity objectives that
asks whether there is a controller (policy) to ensure that the objective holds
with probability 1 (almost-surely). While the qualitative analysis of POMDPs with
parity objectives is undecidable, recent results show that when restricted to
finite-memory policies the problem is EXPTIME-complete. While the problem is intractable
in theory, we present a practical approach to solve the qualitative analysis problem.
We designed several heuristics to deal with the exponential complexity, and have
used our implementation on a number of well-known POMDP examples for robotics
applications. Our results provide the first practical approach to solve the qualitative
analysis of robot motion planning with LTL properties in the presence of uncertainty.

text: 'We present a flexible framework for the automated competitive analysis of
on-line scheduling algorithms for firm- deadline real-time tasks based on multi-objective
graphs: Given a taskset and an on-line scheduling algorithm specified as a labeled
transition system, along with some optional safety, liveness, and/or limit-average
constraints for the adversary, we automatically compute the competitive ratio
of the algorithm w.r.t. a clairvoyant scheduler. We demonstrate the flexibility
and power of our approach by comparing the competitive ratio of several on-line
algorithms, including D(over), that have been proposed in the past, for various
tasksets. Our experimental results reveal that none of these algorithms is universally
optimal, in the sense that there are tasksets where other schedulers provide better
performance. Our framework is hence a very useful design tool for selecting optimal
algorithms for a given application. '

text: 'We consider graphs with n nodes together with their tree-decomposition that
has b = O ( n ) bags and width t , on the standard RAM computational model with
wordsize W = Θ (log n ) . Our contributions are two-fold: Our first contribution
is an algorithm that given a graph and its tree-decomposition as input, computes
a binary and balanced tree-decomposition of width at most 4 · t + 3 of the graph
in O ( b ) time and space, improving a long-standing (from 1992) bound of O (
n · log n ) time for constant treewidth graphs. Our second contribution is on
reachability queries for low treewidth graphs. We build on our tree-balancing
algorithm and present a data-structure for graph reachability that requires O
( n · t 2 ) preprocessing time, O ( n · t ) space, and O ( d t/ log n e ) time
for pair queries, and O ( n · t · log t/ log n ) time for single-source queries.
For constant t our data-structure uses O ( n ) time for preprocessing, O (1) time
for pair queries, and O ( n/ log n ) time for single-source queries. This is (asymptotically)
optimal and is faster than DFS/BFS when answering more than a constant number
of single-source queries.'

text: ' We consider partially observable Markov decision processes (POMDPs) with
a set of target states and every transition is associated with an integer cost.
The optimization objective we study asks to minimize the expected total cost till
the target set is reached, while ensuring that the target set is reached almost-surely
(with probability 1). We show that for integer costs approximating the optimal
cost is undecidable. For positive costs, our results are as follows: (i) we establish
matching lower and upper bounds for the optimal cost and the bound is double exponential;
(ii) we show that the problem of approximating the optimal cost is decidable and
present approximation algorithms developing on the existing algorithms for POMDPs
with finite-horizon objectives. While the worst-case running time of our algorithm
is double exponential, we also present efficient stopping criteria for the algorithm
and show experimentally that it performs well in many examples of interest.'
