According to this site the official competition will be held online from 20th-22nd July. I am curious to know if there will be a mirror contest.
Also what is the status of other contests like JOIOC,COI,CEOI,balkan etc? Want to know because these contests are very good to practice for TST and IOI
AFAIK CEOI is still open to discussion whether it will be held onsite or online. Regarding COI, if by that you mean the Croatian Olympiad in Informatics, the official contest was held yesterday and the online event will probably follow soon. ipaljak will be able to give you some more info on that.
We are in the middle of implementing a new judging system and intend to beta test it on this year's COI. Unfortunately, I'm not sure when will that be and it might even happen after IOI 2020.
I've heard that there will be a mirror of BOI.
We are at the moment still planning to hold an online mirror for the onsite competition next week but dates/times aren’t confirmed yet. We will send an announcement as soon as this is confirmed.
Now that it's been 2-3 months, I was curious if people had updates on this? (BOI and JOIOC had already happened, but I am unaware of what the case is for other contests).
What is TST ?
Team selection test, for IOI.
