2014 — 2015: Mathematics

In the academic year 2014/15 St. Petersburg University together with Euler Foundation holds the united international mathematical olympiad «Formula of Unity» / «The Third Millenium». Secondary/high school students (11-year old and above) are invited to participate.

This Olympiad continues traditions of two Olympiads, one of which — «Formula Of Unity» — was first held in 2012/2013; another — «The Third Millennium» — has been conducted since 2001, and, in its turn, it continues the traditions of Soros Olympiads. In 2013/14 academic year the Olympiad gathered more than 5,000 students from 13 countries. Participation is free of charge.

Announcement of the Olympiad

September 16, 2014

Dear friends!

We are happy to announce the forthcoming international mathematical olympiad «Formulo de Integreco» / «The Third Millennium» conducted by Euler Foundation jointly with Saint Petersburg State University.

Secondary/high school students (11-year old and above) are invited to participate. The Olympiad is held in two rounds. The first (extramural) round will take place from October 1 to October 21, 2014, its problems will be published on October 1 on our website. The second, intramural round will be held simultaneously in many cities of Russia and in other countries on February 1, 2015. This Olympiad continues traditions of two Olympiads, one of which — «Formula Of Unity» — was first held in 2012/2013; another — «The Third Millennium» — has been conducted since 2001, and, in its turn, it continues the traditions of Soros Olympiads. In 2013/14 academic year the Olympiad gathered more than 5,000 students from 13 countries.

Participation is free of charge. Everybody is invited to take part in the first round and the winners will be invited to the second round. Participants with the best results in the second round will be invited to the international mathematical camp «Formulo de Integreco».

We hope that teachers, homeroom teachers and circle tutors would be able to take a considerable part in organizing the first round at their schools and then in evaluation of the first tour problems (see the paragraph «Information for teachers and local coordinators»).

Information for individual participants

The participants are supposed to be school students of grades equivalent to Russian grades 5–11 (table of matching grades). If you are willing to participate you don’t have to report your participation in advance, it’s enough just to send your solutions by October 21, 2014. Solutions are accepted in Esperanto, Russian, English, Spanish, Romanian, Georgian, French or German and are to be submitted via e‑mail in one of the standard formats (doc, txt, odt or pdf) or as scanned hand-written documents. Solutions in other languages may be accepted if agreed with local coordinators. The problems, e‑mail address for submitting solutions, and detailed instructions will be published here on October 1.

It is possible for primary school students (1–4 grades for example) to participate and solve the Olympiad problems if they like.

If you learnt about the Olympiad from your teachers, follow their instructions: your work is likely to be handed to them.

Information for teachers and local coordinators

We would be grateful for any help in coordinating the Olympiad locally thus contributing to our common goal of rising school student interest in mathematics. You may organize participation of students from a class, a school, or an entire town or city. However, it is important that students participate voluntarily and work individually.

After collecting written or typed solutions from the participants you can send them to us no later than on October 22. You will be informed about the results at a later time (depending on the number of participants).

However, instead of this, you can evaluate the solutions yourself. If you choose this option, you will receive correct solutions and criteria for evaluation from us (between October 23 and 27). In this case you will send us only submissions from the participants with the best scores on our request.

If you evaluate the solutions yourself, you will need to send us the list of participants by October 22 and the results of evaluation by November 10 (unless we agree upon a different timeline).

Although it is not necessary to inform us about participation of your group in advance, it will be helpful if you do so by contacting us via e‑mail [email protected]​imi.​ras.​ru. Please provide the following information in your message:

  • The name and the type of the group of participants (a class, a school, a city or a country);
  • Estimated number of participants in this group;
  • Whether you are going to evaluate the solutions yourself.

If you are ready to coordinate the Olympiad and perform the evaluation in a big community such as a city, a region or a country, we will appreciate if you contact us before the beginning of the Olympiad.

The problems of the first round will be published on October 1 in Russian and English, but we are ready to publish them in other languages as well if local coordinators help us with translation. In this case, we will send them the problems to be translated earlier, a few days before the beginning of the first round.

Thank You very much for your participation!

The Organizing Committee
