text: In the analysis of reactive systems a quantitative objective assigns a real
value to every trace of the system. The value decision problem for a quantitative
objective requires a trace whose value is at least a given threshold, and the
exact value decision problem requires a trace whose value is exactly the threshold.
We compare the computational complexity of the value and exact value decision
problems for classical quantitative objectives, such as sum, discounted sum, energy,
and mean-payoff for two standard models of reactive systems, namely, graphs and
graph games.

text: A Rapidly-exploring Random Tree (RRT) is an algorithm which can search a non-convex
region of space by incrementally building a space-filling tree. The tree is constructed
from random points drawn from system’s state space and is biased to grow towards
large unexplored areas in the system. RRT can provide better coverage of a system’s
possible behaviors compared with random simulations, but is more lightweight than
full reachability analysis. In this paper, we explore some of the design decisions
encountered while implementing a hybrid extension of the RRT algorithm, which
have not been elaborated on before. In particular, we focus on handling non-determinism,
which arises due to discrete transitions. We introduce the notion of important
points to account for this phenomena. We showcase our ideas using heater and navigation
benchmarks.

text: Signal regular expressions can specify sequential properties of real-valued
signals based on threshold conditions, regular operations, and duration constraints.
In this paper we endow them with a quantitative semantics which indicates how
robustly a signal matches or does not match a given expression. First, we show
that this semantics is a safe approximation of a distance between the signal and
the language defined by the expression. Then, we consider the robust matching
problem, that is, computing the quantitative semantics of every segment of a given
signal relative to an expression. We present an algorithm that solves this problem
for piecewise-constant and piecewise-linear signals and show that for such signals
the robustness map is a piecewise-linear function. The availability of an indicator
describing how robustly a signal segment matches some regular pattern provides
a general framework for quantitative monitoring of cyber-physical systems.

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.
