## About SynCoP

**Due to the pandemics, SynCoP has neither taken place in 2020 nor in 2021. SynCoP however took place during ETAPS’22 in Munich and will take place during ETAPS’23 in Paris.**

This event is an ETAPS workshop organised as a series of invited talks and submitted contributions. Everyone is welcome to attend and participate in the discussions. There are no formal proceedings.

### Scientific objective of SynCoP

SynCoP aims at bringing together researchers working on verification and parameter synthesis for systems with discrete or continuous parameters, in which the parameters influence the behaviour of the system in ways that are complex and difficult to predict. Such problems may arise for real-time, hybrid or probabilistic systems in a large variety of application domains. The parameters can be continuous (e.g. timing, probabilities, costs) or discrete (e.g. number of processes). The goal can be to identify suitable parameters to achieve desired behaviour, or to verify the behaviour for a given range of parameter values.

Systems composed of a finite but possibly arbitrary number of identical components occur everywhere from hardware design (e.g. cache coherence protocols) to distributed applications (e.g. client-server applications). Parameterised verification is the task of verifying the correctness of this kind of systems regardless the number of their components.

#### Topics of SynCoP

The scientific subject of the workshop covers (but is not limited to) the following areas:

- parameter synthesis,
- parametric model checking,
- regular model checking,
- robustness analysis,
- parameterised logics, decidability and complexity issues,
- formalisms such as parametric timed and hybrid automata, parametric time(d) Petri nets, parametric probabilistic (timed) automata, parametric Markov Decision Processes, networks of identical processes,
- specifications in automata and logic, term and graph rewriting, Petri nets, process algebra, …
- validation methods via assertional and regular model checking, reachability and coverability decision procedures, abstractions, theorem proving, constraint solving, …
- interactions between discrete and continuous parameters,
- tools and applications to hardware design, cache coherence protocols, security and communication protocols, multithreaded and concurrent programs, programs with relaxed memory models, mobile and distributed systems, database languages and systems, biological systems, …
