Subject: [IOI-announce] Invitation to TOKI Open 2017

Hello everyone!

I am Jonathan, the current Scientific Committee of Indonesian Olympiad Informatics. I have been involved in “delegating" Indonesia for several recent international competitions, including translating APIO 2016 tasks and being the deputy leader for Indonesian IOI 2016 team.

After we successfully organized TOKI Open 2014 we are going to do the similar thing this year. We will open our current IOI Selection Contest to international participants. We call it TOKI Open 2017. TOKI stands for Tim Olimpiade Komputer Indonesia, or Indonesian Computing Olympiad Team in English.

Objectives of us opening this contest include, but not limited to:
• Measure the performance of our IOI trainee compared to other countries' IOI trainee.
• Foster friendship between Indonesia and other IOI participating countries.
• Test Indonesia's scientific committee capability in setting IOI-level problems.
• Test Indonesia's technical committee capability in hosting IOI-level contests.

The contest will have very similar rules and format with IOI, as this contest will be used to select our Top 4 and train our Top 4 for IOI. We expect that the difficulty of the contest is almost the same as IOI. Therefore, this contest is suitable for those who are preparing for IOI. The problems will be available in both Bahasa Indonesia and English.

The contest will be conducted on TLX Online Judge You may need to register for a TLX Account if you do not have one. If you have a TLX account, you can login and go to the contest link to register for the contest. There will be two competition days, each having three problems. Each competition day will have two open windows containing the same problemset, so you can participate in either one of the window depending your time preference.

1. Day 1 : Wednesday, 10 May 2017
o Window 1 : 1.30AM — 6.30AM UTC (8.30AM — 1.30PM Western Indonesian Time). Contest Link.
o Window 2 : 12.00PM — 5.00PM UTC (7.00PM — 12.00AM Western Indonesian Time). Contest Link.
2. Day 2 : Friday, 12 May 2017
o Window 1 : 6.30AM — 11.30AM UTC (1.30PM — 6.30PM Western Indonesian Time). Contest Link.
o Window 2 : 12.00PM — 5.00PM UTC (7.00PM — 12.00AM Western Indonesian Time). Contest Link.

IMPORTANT: You are not allowed to register on both windows for the same competition day, since they will have the same problemset. If you have registered on a wrong window, you can go to the contest link to unregister.

We invite everyone (especially eligible IOI participants) to participate in this contest. If you are a delegation leader of a country, we invite you to invite your students to participate in this contest (maybe to include this competition in your official training programme) .

See you at the leaderboard.

PS : Information about this contest is also published on Codeforces We will use the post in Codeforces for updates. Stay tuned!

Subject: [IOI-announce] Minor change to IOI eligibility rules

Dear friends and colleagues,

Over the last year, the IC has been discussing the eligibility rules for contestants at the IOI. We wish to make a minor change, which we plan to put to the General Assembly during IOI 2017.

This email is to request feedback from team leaders. Our intention is just to remove ambiguity - that is, to make the rules more precise. We hope we have done this in a way that should not have any negative impact upon national delegations. However, if you feel that this change will affect your delegation in a negative way then we encourage you to contact us at ioi-ic@lists.ioinformatics.org before the IOI begins, so that we can make any necessary changes.

The current rule states:

“S2.5. A Contestant is a student who was enrolled at a school for secondary education, in the Country they are representing, during the period September to December in the year before IOI’n, and is not older than twenty years on the 1st of July of the year of IOI’n. Students who are studying abroad may represent the Country of their nationality.”

Our new proposal is:

“S2.5. A Contestant is a student who was enrolled at a school for secondary education, in the Country they are representing, for the majority of the period 1 September to 31 December in the year before IOI’n, and is not older than twenty years on the 1st of July of the year of IOI’n. Students who are studying abroad may represent the Country of their nationality.”

The reason for this change is to capture the spirit of the rule (that contestants are at school for the second half of year n-1), but to avoid technical problems for countries that (for example) do not start their school year until October, or that finish their school year in November.

We hope that this is a simple and uncontroversial change - however, once again: if you think that it may cause problems for your delegation then please contact the IC during the next month so that we can discuss the issue before IOI 2017 begins.

Best regards and see you in Tehran,

- Ben (on behalf of the IC).
