International Challenge on the Rigorous Examination of Reactive Systems 2017 (RERS)

co-located with ISSTA and SPIN 2017

Santa Barbara, California, USA | July 12, 2017

The RERS Challenge 2017: is the 7th International Challenge on the Rigorous Examination of Reactive Systems and is co-located with ISSTA/SPIN 2017. The event will be held in July 2017, in Santa Barbara, 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 lines to tens of thousands of them), to exploited language features (arrays and index arithmetics). 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 then the only challenge with a special track for LTL analysis on synthesized benchmarks.

The main aims of RERS 2017 are to:

  • encourage the combination of usually different research fields for better software verification results
  • provide a comparison foundation based on differently tailored benchmarks that reveals the strengths and weaknesses of specific approaches
  • initiate a discussion for better benchmark generation reaching out across the usual community barriers to provide benchmarks useful for testing and comparing a wide variety of tools

There will be a 1 day workshop where the results will be presented, the generation methodology will be explained, and the modalities for the RERS 2018 challenge, which will be part of ISoLA 2018 will be discussed.
