text: 'In two-player finite-state stochastic games of partial observation on graphs,
in every state of the graph, the players simultaneously choose an action, and
their joint actions determine a probability distribution over the successor states.
The game is played for infinitely many rounds and thus the players construct an
infinite path in the graph. We consider reachability objectives where the first
player tries to ensure a target state to be visited almost-surely (i.e., with
probability 1) or positively (i.e., with positive probability), no matter the
strategy of the second player. We classify such games according to the information
and to the power of randomization available to the players. On the basis of information,
the game can be one-sided with either (a) player 1, or (b) player 2 having partial
observation (and the other player has perfect observation), or two-sided with
(c) both players having partial observation. On the basis of randomization, (a)
the players may not be allowed to use randomization (pure strategies), or (b)
they may choose a probability distribution over actions but the actual random
choice is external and not visible to the player (actions invisible), or (c) they
may use full randomization. Our main results for pure strategies are as follows:
(1) For one-sided games with player 2 having perfect observation we show that
(in contrast to full randomized strategies) belief-based (subset-construction
based) strategies are not sufficient, and we present an exponential upper bound
on memory both for almost-sure and positive winning strategies; we show that the
problem of deciding the existence of almost-sure and positive winning strategies
for player 1 is EXPTIME-complete and present symbolic algorithms that avoid the
explicit exponential construction. (2) For one-sided games with player 1 having
perfect observation we show that nonelementarymemory is both necessary and sufficient
for both almost-sure and positive winning strategies. (3) We show that for the
general (two-sided) case finite-memory strategies are sufficient for both positive
and almost-sure winning, and at least nonelementary memory is required. We establish
the equivalence of the almost-sure winning problems for pure strategies and for
randomized strategies with actions invisible. Our equivalence result exhibit serious
flaws in previous results of the literature: we show a nonelementary memory lower
bound for almost-sure winning whereas an exponential upper bound was previously
claimed.'

text: Recently, there has been an effort to add quantitative objectives to formal
verification and synthesis. We introduce and investigate the extension of temporal
logics with quantitative atomic assertions. At the heart of quantitative objectives
lies the accumulation of values along a computation. It is often the accumulated
sum, as with energy objectives, or the accumulated average, as with mean-payoff
objectives. We investigate the extension of temporal logics with the prefix-accumulation
assertions Sum(v) ≥ c and Avg(v) ≥ c, where v is a numeric (or Boolean) variable
of the system, c is a constant rational number, and Sum(v) and Avg(v) denote the
accumulated sum and average of the values of v from the beginning of the computation
up to the current point in time. We also allow the path-accumulation assertions
LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring to the average value along an
entire infinite computation. We study the border of decidability for such quantitative
extensions of various temporal logics. In particular, we show that extending the
fragment of CTL that has only the EX, EF, AX, and AG temporal modalities with
both prefix-accumulation assertions, or extending LTL with both path-accumulation
assertions, results in temporal logics whose model-checking problem is decidable.
Moreover, the prefix-accumulation assertions may be generalized with "controlled
accumulation," allowing, for example, to specify constraints on the average
waiting time between a request and a grant. On the negative side, we show that
this branching-time logic is, in a sense, the maximal logic with one or both of
the prefix-accumulation assertions that permits a decidable model-checking procedure.
Extending a temporal logic that has the EG or EU modalities, such as CTL or LTL,
makes the problem undecidable.

text: 'We study two-player (zero-sum) concurrent mean-payoff games played on a finite-state
graph. We focus on the important sub-class of ergodic games where all states are
visited infinitely often with probability 1. The algorithmic study of ergodic
games was initiated in a seminal work of Hoffman and Karp in 1966, but all basic
complexity questions have remained unresolved. Our main results for ergodic games
are as follows: We establish (1) an optimal exponential bound 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); (2) the approximation problem lies in FNP; (3) the approximation problem
is at least as hard as the decision problem for simple stochastic games (for which
NP ∩ coNP is the long-standing best known bound). We present a variant of the
strategy-iteration algorithm by Hoffman and Karp; show that both our algorithm
and the classical value-iteration algorithm can approximate the value in exponential
time; and identify a subclass where the value-iteration algorithm is a FPTAS.
We also show that the exact value can be expressed in the existential theory of
the reals, and establish square-root sum hardness for a related class of games.'

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: 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: 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.

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: 'Recently there has been a significant effort to add quantitative properties
in formal verification and synthesis. While weighted automata over finite and
infinite words provide a natural and flexible framework to express quantitative
properties, perhaps surprisingly, several basic system properties such as average
response time cannot be expressed with weighted automata. In this work, we introduce
nested weighted automata as a new formalism for expressing important quantitative
properties such as average response time. We establish an almost complete decidability
picture for the basic decision problems for nested weighted automata, and illustrate
its applicability in several domains. '

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. The vertices
of the two graphs are the same, and each vertex corresponds to an individual.
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. Our main results
are: (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). (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.'

text: "Two-player games on graphs provide the theoretical framework for many important
problems such as reactive synthesis. While the traditional study of two-player
zero-sum games has been extended to multi-player games with several notions of
equilibria, they are decidable only for perfect-information games, whereas several
applications require imperfect-information games.\r\nIn this paper we propose
a new notion of equilibria, called doomsday equilibria, which is a strategy profile
such that all players satisfy their own objective, and if any coalition of players
deviates and violates even one of the players objective, then the objective of
every player is violated.\r\nWe present algorithms and complexity results for
deciding the existence of doomsday equilibria for various classes of ω-regular
objectives, both for imperfect-information games, and for perfect-information
games.We provide optimal complexity bounds for imperfect-information games, and
in most cases for perfect-information games."
