Dear colleagues,


  4th International Workshop on Symbolic and Numerical Methods for
  Reachability Analysis ( http://snr2018.verivital.com/ )

will be held on Friday 20 April 2018 at Thessaloniki, Greece, as an
affiliated workshop of ETAPS 2018. Registration is open through the ETAPS
web site ( https://www.etaps.org/index.php/2018/registration ).


System verification increasingly has to address systems that combine
discrete and continuous components, like hybrid systems or floating-point
software. 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 such 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.

SNR brings together researchers working in the area of automated
analysis and synthesis of systems combining discrete and continuous
