The man who broke the 4000 Elo barrier in programming
In short: In the world of competitive programming, Gennady Korotkevich is often cited as the greatest of all time. He didn't just master the craft; he pushed the limits of human performance so far that he forced the industry to create a new category just to describe his skill.
Born in Gomel, Belarus, Korotkevich began his journey at age 6, influenced by his parents who were programmers in a mathematics department. By age 8, his father designed a children's game to help him learn. His early talent was staggering; at age 11, he qualified for the International Olympiad in Informatics (IOI), setting a world record by a significant margin. By the time he was a second-grader, he had already won a national competition, securing an automatic entry into a technical university by solving a complex physics problem involving buoyancy before he had even learned Archimedes' principle.
Korotkevich's career is defined by a relentless accumulation of titles. He won six consecutive gold medals at the IOI and became the first person to break the 4000 Elo rating barrier on Codeforces on August 30, 2024. This feat was so significant that it necessitated the creation of a new rank above 'Legendary Grandmaster'—a category named 'Tourist' in his honor.
This new rank features a unique 'inverted' color scheme for handles, where the first letter is red and the rest are black, a distinction shared by only one other user, 'jiangly'. Despite his dominance, Korotkevich has maintained a humble perspective on his abilities. During the 2009 IOI, he stated he was no genius but simply good at trying various strategies until one worked. He famously spent only three to four hours a day at the computer, prioritizing hobbies like football and table tennis. Even after receiving lucrative job offers from tech giants like Google and Yandex, he chose to prioritize his education, pursuing a PhD at ITMO University in Russia before eventually joining Cognition AI. ], 100, 3,
