On September 28, we slightly refined the wording of the 2nd problem in the homework round of category Z7. If you downloaded the problems before, we recommend checking the current version.
On 3–13 July 2023, the 64th year of the International Mathematical Olympiad (IMO) was held in Chiba, Japan (which is a suburb of Tokyo). It was attended in total by 618 competitors from 112 countries. Each country could send a maximum of 6 contestants.
Slovakia was represented by:
During two days (July 8 and 9), the students solved two sets of problems, for each problem it was possible to get a maximum of 7 points. The full number of 42 points was obtained by 5 competitors, namely to one participant from South Korea, Romania, USA and two from China. Russia as the state was officially excluded from participation in the IMO for understandable reasons.
The thresholds for winning the bronze, silver and gold medals were staggered this year 18, 25 and 32 points. According to IMO rules, about half of the participants win medals and they share gold, silver and bronze in the ratio 1 : 2 : 3. Honorable mention is given to those students who have solved at least one problem for full number of points.
The results of the Slovak team members can be found in the results section.
In the unofficial ranking of countries, which is created by adding up the points of the entire team, we were ranked 39th, which is a slight improvement over last year. Although we beat the Czech Republic again in the traditional derby (45th), our other partners from V4 Poland and Hungary are ahead of us (32nd and 20th, respectively). The top 5 were China, USA, South Korea, Romania and Canada. Complete results and statistics can be found on the website www.imo-official.org.
Slovakia is already regularly involved in creating problems at the IMO. This year, two Slovak geometric problems from the creative workshop of Patrik Bak made it into the shortlist of 30 problems, but this time none of them made it to the final six.
The problems for the contest are selected from the shortlist through a demanding process lasting several hours in a kind of a "parliament", whose members are the leaders of all delegations. The problems are always elected so that all four areas are represented as evenly as possible, namely algebra, geometry, combinatorics and number theory. On individual days, problems are usually ordered according to expected difficulty.
The next edition of the IMO will be held after five years again in Bath, UK, in July 2024. Australia (2025) and China (2026) will follow.
