News & Events

October 23, 2017

Dear IOI Colleagues,

Good news: the volumes 11th (both books) are already accepted in Scopus, the all 30 papers!

We need more people in the Editorial Board and Reviewers, please suggest yourself or ask your colleagues if they are interested in the journal. We really need more academic persons to work with the IOI journal papers.

Also, I would like to inform you that it is time to write papers to the next year volume of "Olympiads in Informatics". It's quality depends on all of us. Please think, investigate and submit papers.
Also, if you know somebody from your colleagues (especially earlier years participants) who can submit an interesting paper let me know. I remind that we can publish few good papers without participation in IOI. So we are flexible.

Call for Papers


The 12th conference will be held concurrently with the 2018 International Olympiad in Informatics, taking place in Tsukuba, Japan, September 1 - 8. The IOI conference considers covers national and international informatics contests, and offers an opportunity to bring together the collected knowledge and experiences from many events which currently take place across the globe.

Please submit your proposals (title and short abstracts, few sentences) for papers until end of January to Valentina Dagiene. The full papers are to be submitted by end of March 2017. We need time for reviewing.

If you would like to read papers from the previous IOI conferences you can find them on the IOI website.

IMPORTANT. As previous years, the papers will be divided into two groups: research papers and country reports. Please, inform me who is going to submit national reports as well.
For research papers - 8-18 pages,
For national reports - 4-8 pages.

Additional interesting information for IOI community would be good as well: review of books, presenting an interesting task or explanation solution, describing programming games, etc. Be creative to suggest new interesting items!

If you need more information do not hesitate to send me emails.

I am very thankful for your interest and helping me to find authors.

Best regards,
Valentina Dagiene

International Olympiads in Informatics in Teams
October 23, 2017

For the first time, the International Olympiads in Informatics in Teams (with the official participation of Italy, Romania and Russia) will be mirrored into online contests. These contests, of a lower difficulty level than those of the IOI, are intended for teams of 4 contestants from the same high school. Everyone is welcome to participate, especially if you are considering to join officially the IOIT in the future!

The mirror contests timing will be USACO-like: it will be open for 24 hours but you will be able to compete for up to 3 hours (you can decide when to "start" your time window, after the login). Participation will be available upon registration to the Italian trainings website (localized also in English). The problem statements will be available in English only, and the languages allowed are C, C++ and Pascal. Every contest will consist of 7 problems (see for further information).

Note: you can decide when to start your 3 hour time window, but remember that the contest will end at 24 hours after the start of the official contest regardless of your time window!

If you want to participate, you must:

    Visit the training website:
    Click "Sign up" (if you haven't already done it previously)
    Fill out the form and then confirm
    Visit the contest list:
    Click on the OIS2018 --  list entry
    Log in with the same username and password you used to sign up
    If the login is successful you will be ready to participate, just wait for the contest to start! (and maybe save the page in your bookmarks, so that you can quickly get back to it when the contest begins)
    When the contest starts, you will see a red button. Click it when you want to start your 3 hour time window!
    The ranking for each contest will be available at only when each contest ends.
    Good luck and have fun!

The schedule of the contests is the following (starting times in the CEST/CET time zone):

    Practice: from oct. 23 to oct. 27 (whole days)
    Round 1: oct. 30 @ 15:00
    Round 2: nov. 28 @ 15:00
    Round 3: dec. 20 @ 14:30
    Round 4: jan. 25 @ 14:30
    Finals: feb. 16 @ 11:00

We hope that you will join us or encourage your students to do so!
