SNR 2018

4th International Workshop on Symbolic and Numerical Methods for
Reachability Analysis

April 14, 2018, Thessaloniki, Greece
Affiliated with ETAPS 2018

Important Dates

Abstract submission: January 10, 2018
Paper submission: January 18, 2018
Notification: February 18, 2018
Final version: March 3, 2018
Workshop date: April 14, 2018


Cyber-physical systems are complex dynamical systems that combine discrete
and continuous components and therefore feature hybrid
discrete-continuous state. Reachability questions, regarding whether a
system can run into a certain subset of its state space, stand at the core
of verification and synthesis problems for hybrid systems and their
embedded control software. Many successful reachability analysis methods
for hybrid systems connect techniques from two major research areas:

- Symbolic methods that encode reachability properties as logical
formulas, resorting to constraint solvers, model checking algorithms,
and theorem provers for discharging proof obligations over the resulting
predicative representations of systems and state sets.

- Numerical methods that operate on various forms of numerical
approximations of reachable state sets and system dynamics, like verified

The SNR workshop is a platform for seeking further synergies between these
two types of techniques already interacting closely in the existing
approaches for reachability analysis. The workshop aims to catalyze work on
the interface of symbolic and numerical methods for reachability
analysis, automated system verification, correct-by-construction
system synthesis, and planning in hybrid-state dynamical systems. It
solicits submissions broadly in the area of analysis and
synthesis of continuous and hybrid systems. The scope of the workshop
includes, but is not restricted to, the following topics:

- Verification of hybrid systems
- Flow-pipe construction; symbolic representation of regions in
reachability analysis algorithms
- Abstraction techniques for hybrid systems and numerical programs
- Trajectory generation from symbolic paths; counterexample computation
- Symbolic and reliable integration
- Bounded model-checking, symbolic simulation, and related techniques
- Decision procedures over real numbers; logics to reason about hybrid
- Automated deduction and invariant generation for hybrid systems
- Reachability analysis for planning and synthesis
- Stochastic/probabilistic hybrid systems
- Domain-specific approaches in biology, robotics, cyber-physical systems
(CPS), embedded software, etc.
