As of today, the benchmark set for SYNTCOMP 2014 is fixed. Overall, we have collected 6 sets of benchmarks, with more than 500 individual synthesis problems. The benchmarks are available in our Bitbucket repository
on the Synthesis Competition Server (after registration). Of course we still welcome new benchmarks, but they will not be used in the 2014 competition anymore.
Solver submission for 2014 is open on the same server. If you are developing a synthesis tool for the competition, please have a look at the reference implementation and testing framework, and submit a first version of your tool until End of May 2014.
