The RERS Challenge 2017 is the 7th International Challenge on the Rigorous Examination of Reactive Systems and is co-located with the SPIN Symposium 2017. The event will be held on July 12th 2017 in Santa Barbara, California, USA. RERS is designed to encourage software developers and researchers to apply and combine their tools and approaches in a free style manner to answer evaluation questions for reachability and LTL formulas on specifically designed benchmarks. The goal of this challenge is to provide a basis for the comparison of verification techniques and available tools.

The benchmarks are automatically synthesized to exhibit chosen properties and then enhanced to include dedicated dimensions of difficulty, ranging from conceptual complexity of the properties (e.g. reachability, full safety, liveness), over size of the reactive systems (a few hundred to tens of thousands lines of code), to contained language features (arrays and index arithmetic). They are therefore especially suited for community-overlapping tool comparisons. What distinguishes RERS from other challenges is that the challenge problems can be approached in a free-style manner: it is highly encouraged to combine and exploit all known (even unusual) approaches to software verification. In particular, participants are not constrained to their own tools. To clearly separate RERS from other challenges, this year the LTL analysis is separated from the reachability of labels. RERS is the only challenge with a special track for LTL analysis on synthesized benchmarks.
