Organization change due to pandemic situation

Due to the pandemic situation worldwide, the Program Committee and the organizers of the TTC decided that the TTC 2020 will be held as an online event, decoupled from STAF unlike earlier announcements. In particular, we plan the folowing changes compared to previous editions:

  • The event will take place as a free online event. We are evaluating technical options to host an online event.
  • The plan for TTC is to have a synchronized virtual event where solution authors do present their solutions and answer questions from opponent solutions afterwards. However, we also plan to record the event such that the presentations can be viewed later on (provided we get the presenters consent).
  • The fact that we are decoupled from the STAF schedule means that we can be more flexible in terms of timelines. We have therefore extended the solution submission deadline to 15th of June.
  • The TTC 2020 will not offer a live contest.
