Spot is a C++ 17 library for LTL and ω-automata manipulation, with command-line utilities,
and Python bindings. This paper summarizes its evolution over the past six years, since the …

Abstract We present Spot 2.0, a C++ library with Python bindings and an assortment of
command-line tools designed to manipulate LTL and ω-automata in batch. New automata …

We provide the first solution for model-free reinforcement learning of ω-regular objectives for
Markov decision processes (MDPs). We present a constructive reduction from the almost …

We present the library Owl (O mega-W ords, automata, and L TL) for ω-automata and linear
temporal logic. It forms a backbone of several translations from LTL to automata and related …

The formal analysis of critical systems is supported by a vast space of modelling formalisms
and tools. The variety of incompatible formats and tools however poses a significant …

We report on the last four editions of the reactive synthesis competition (SYNTCOMP 2018–
2021). We briefly describe the evaluation scheme and the experimental setup of …

HyperLTL is a temporal logic that can express hyperproperties, ie, properties that relate
multiple execution traces of a system. Such properties are becoming increasingly important …

The synthesis of reactive systems from linear temporal logic (LTL) specifications is an
important aspect in the design of reliable software and hardware. We present our adaption …

Quantitative formal models capture probabilistic behaviour, real-time aspects, or general
continuous dynamics. A number of tools support their automatic analysis with respect to …

The expanding role of reinforcement learning (RL) in safety-critical system design has
promoted ω-automata as a way to express learning requirements—often non-Markovian …
