58th International Mathematical Olympiad (IMO) 2017

Rio de Janeiro will host the 58th International Mathematical Olympiad (IMO 2017), the first IMO edition to be held in Brazil. During this period we will receive the most talented young students from more than 100 countries around the world, who will come together to solve challenging mathematical problems in a friendly competition.

Hosted by Instituto Nacional de Matemática Pura e Aplicada (IMPA), the IMO 2017 will be held jointly with the International Congress of Mathematicians ICM 2018, as part of the Biennium of Mathematics 2017–2018 Gomes de Souza, an initiative that aims to disseminate mathematical and scientific knowledge throughout society.

The aims of the IMO are:

  • to discover, encourage and challenge mathematically gifted young people in all countries;
  • to foster friendly international relationships among mathematicians of all countries;
  • to create an opportunity for the exchange of information on school syllabuses and practices throughout the world;
  • to promote mathematics generally.

Schedule for 58th IMO 2017 is given below.

58th IMO Exam held from 12 to 24 Jul 2017


A Country’s Contestants should normally be citizens or residents of that Country, and should be selected through that Country’s national Mathematical Olympiad or equivalent selection programme. Contestants must not have formally enrolled at a university or any other equivalent post-secondary institution, and they must have been born less than twenty years before the day of the second Contest paper.

Each invited Country wishing to participate in an IMO must confirm their participation online at www.imo-official.org/registration using the username and password provided by the Host Organisation, no later than the date specified in the Annual Regulations. This also confirms that the Leader agrees to abide by the General Regulations and the Annual Regulations for that IMO. Participants, Observers and their travel details must be registered by the dates specified in the Annual Regulations.

Leaders and Deputy Leaders are responsible for the conduct of the Contestants, and for the avoidance of doubt the Leaders and Deputy Leaders are acting in loco parentis for their Contestants except where the Host Organisation has been notified in writing that an Observer has been nominated to act in loco parentis.


Contest Regulations

The contest element of an IMO (the “Contest”) takes place on two consecutive days specified in the Annual Regulations, neither of which should normally be a Friday, Saturday or Sunday, under the direction of the Chief Invigilator appointed by the Host Organisation. On each day of the Contest the examination starts in the morning and lasts for four and a half hours. Each of the two examination papers consists of three problems.

Each Contestant may receive the problems in one or two languages, previously requested on the registration form, provided that the Jury has approved the relevant translation.

Each Contestant must work independently and submit solutions in his/her own language. The solutions must be written on answer forms provided by the Host Organisation. Contestants must write on only one side of each answer form.

The only instruments permitted in the Contest are writing and drawing instruments, such as rulers and compasses. In particular, books, papers, tables, calculators, protractors, computers and communication devices are not allowed into the examination room.

The Jury, Observers and any others who have any knowledge of the problems and solutions before the examinations must do their utmost to ensure that no Contestant has any information, direct or indirect, about any proposed problem. They must also ensure that all Contest problems and solutions are kept strictly confidential until after the entire Contest has finished. They are barred, from the moment of their arrival at the Jury site until the conclusion of the second examination, from having any external communication with Contestants, Deputy Leaders and Observers B and C.

However, if such communication becomes necessary because of an emergency, the Host Organisation must provide proper assistance. Similarly, Contestants, Deputy Leaders and Observers B and C are barred from contacting Leaders and Observers A during the same period of time. Information about arrivals, delays and similar messages are to be directed exclusively to the published IMO office and may be forwarded by the office to the Leaders upon request.

The total number of prizes (first, second and third) must be approved by the Jury and should not normally exceed half the total number of Contestants. The numbers of first, second and third prizes must be approximately in the ratio 1:2:3.

Special prizes may be awarded for solutions considered outstanding by the Jury. Proposals for such special prizes are put forward by the Chief Coordinator appointed by the Host Organisation.

The prizes are awarded at the Closing Ceremony. Each Contestant who has not received a first, second or third prize receives a Certificate of Honourable Mention if he/she has received seven points for the solution of at least one problem.

Each Participant and Observer receives a Certificate of Participation.

Entire Agreement and Understanding

The Participants and Observers acknowledge that these Regulations, and the documents referred to herein, constitute the full agreement and understanding of their parties and supersede any previous discussions or representations made by or on the behalf of the Host Organisation in respect of an IMO.

Force Majeure

In these Regulations, “force majeure” means any cause preventing the Host Organisation from performing any or all of its obligations that arises from or is attributable to acts, events, omissions or accidents beyond the reasonable control of the party so prevented, including without limitation strikes, lock-outs or other industrial disputes (whether involving the workforce of the party so prevented or of any other party), act of God, war, riot, civil commotion, malicious damage, compliance with any law or governmental order, rule, regulation or direction, accident, breakdown of plant or machinery, earthquake, typhoon, fire, flood, storm, or default of suppliers or sub-contractors.

If the Host Organisation is prevented from or delayed in performing any of its obligations to the Participants and Observers under these Regulations by force majeure, it has no liability in respect of the performance of those obligations affected by the force majeure events, both during the continuation of such events and for such time after they cease as is necessary for the Host Organisation to recommence its affected operations in order for it to perform its obligations.
