We introduce Spectra, a new specification language for reactive systems, specifically
tailored for the context of reactive synthesis. The meaning of Spectra is defined by a …

Multi-dimensional mean-payoff and energy games provide the mathematical foundation for
the quantitative study of reactive systems, and play a central role in the emerging …

We propose a general framework for modelling and formal reasoning about multi-agent
systems and, in particular, multi-stage games where both quantitative and qualitative …

In recent years, there has been a growing need and interest in formally reasoning about the
quality of software and hardware systems. As opposed to traditional verification, in which …

We consider lexicographic bi-objective problems on Markov Decision Processes (MDPs),
where we optimize one objective while guaranteeing optimality of another. We propose a …

We present a new and flexible approach to repair reactive programs with respect to a
specification. The specification is given in linear-temporal logic. Like in previous …

Two-player quantitative zero-sum games provide a natural framework to synthesize
controllers with performance guarantees for reactive systems within an uncontrollable …

We consider two-player games played on weighted directed graphs with mean-payoff and
total-payoff objectives, two classical quantitative objectives. While for single-dimensional …

Machine learning and formal methods have com-plimentary benefits and drawbacks. In this
work, we address the controller-design problem with a combination of techniques from both …

the quantitative study of reactive systems, and play a central role in the emerging …
