  We report on the fourth reactive synthesis competition (SYNTCOMP 2017). We
introduce two new benchmark classes that have been added to the SYNTCOMP
library, and briefly describe the benchmark selection, evaluation scheme and
the experimental setup of SYNTCOMP 2017. We present the participants of
SYNTCOMP 2017, with a focus on changes with respect to the previous years and
on the two completely new tools that have entered the competition. Finally, we
present and analyze the results of our experimental evaluation, including a
ranking of tools with respect to quantity and quality of solutions.
