We/I would like to participate anonymously. We/I are aware that this means that our/my ranking results will be published under a generic name (e.g. “participant A”) on the RERS website and at the RERS event. We/I understand that we/I will not earn any achievements.

If you have completed all (or some) tasks, we kindly request you to submit your solution in a CSV-style format. Solutions for each of the problems should be specified in the following way:



  • <number> is the problem specification number.
  • <spec> is the property specification identifier, where numbers 0 to 99 correspond to the LTL or Reachability properties for each problem or error number respectively.
  • <answer> expresses whether or not you believe this error label to be reachable, or the respective LTL property to be satisfied as true/false.

Hence, a line in this file for a hypothetical problem 0 and the error label 37 might look like this:

0, 37, true

Please choose a name for each of the CSV- which clearly identifies the respective problem along with an ID uniquely identifying the solution as yours such as "problemX-<id>.csv". You are free to generate one file for each problem or combine all solutions into a global CSV file. If you split your solutions into several files, please provide them as a ZIP or (compressed) TAR archive.
