Opening this thread for discussion of APIO 2020.
Not really sure whether the problems themselves can be discussed yet (open contest) but the competition has officially ended :)
Edit 1: APIO 2020 Scientific Committee note: "As you mentioned, please refrain from publicly discuss APIO 2020 problems as there will still be an APIO 2020 open contest (public). We can publicly discuss the problems once the open contest has finished."
Feel free to discuss results, we'll only be able to discuss problem content after the open contest ends.
Edit 2: Should be good now :)
