The RERS 2017 Challenge and Workshop

RERS is an annual verification challenge that focuses on LTL and reachability properties of reactive systems. In 2017, RERS was extended to a one day workshop that in addition to the original challenge program also featured an invited talk about possible future developments. As a satellite of ISSTA and SPIN, the 2017 RERS Chal- lenge itself increased emphasis on the parallel benchmark problems which, like their sequential counterparts, were generated using property-preserving transformations in order to scale their level of difficulty. The first half of the RERS workshop focused on the 2017 benchmark profiles, the evaluation of the received contributions, and short presentations of each participating team. The second half comprised discussions about attractive problem scenarios for future benchmarks, like race detection, the topic of the invited talk, and about systematic ways to leverage a tool’s performance based on competition benchmarks and machine learning
