Scope

Hybrid systems are complex dynamical systems that combine discrete and continuous components. 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.

There are several successful methods for hybrid systems reachability analysis. Some methods explicitly construct flow-pipes that over-approximate the set of reachable states over time, where efficient computation of such over-approximations requires symbolic representations such as support functions. Other methods based on satisfiability checking technologies, symbolically encode reachability properties as logical formulas, while solving such formulas requires numerically-driven decision procedures. Last but not least, also automated deduction and the usage of theorem provers led to efficient analysis approaches. The goal of this workshop is to bring together researchers working with different reachability analysis techniques and to seek for synergies between the different approaches.

Topics

The SNR workshop solicits papers 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 with application to continuous and hybrid systems:

  • Reachability analysis
  • Flow-pipe construction; symbolic state set representations
  • Logical frameworks for reasoning
  • Bounded model checking
  • Automated deduction
  • Invariant generation
  • Symbolic execution
  • Trajectory generation; counterexample computation
  • Abstraction techniques
  • Reliable integration
  • Simulation
  • Reachability analysis for planning and synthesis
  • Domain-specific approaches in biology, robotics, etc.
  • Stochastic hybrid systems
  • Probabilistic hybrid systems
