Early Life
Interested in both math and computer science from an early age, Benjamin Qi was a quarterfinalist at the 2015 MATHCOUNTS[7], and an honorable mention at both the 2018 and 2019 USA Mathematical Olympiad.[8] He completed his first USACO competition in December 2015.[9] He attended Princeton High School from 2015 to 2019.
Competitive Programming
Benjamin Qi qualified for the USA's IOI time three times: in 2017, 2018, and 2019.[10] Unable to attend the 2017 IOI, held in Iran, due to visa issues, he successfully attended the 2018 and 2019 IOIs, held in Tsukuba, Japan and Baku, Azerbaijan respectively.
IOI Wins
At the 2018 IOI, Benjamin scored 499 out of 600 points, 30 points more than second place Maolong Yang.[11][12] He was the only contestant to fully solve the challenging algorithmic problems "Seats" and "Highway Tolls". At the 2019 IOI, which involved over 600 students from 88 countries[13], Benjamin scored 547.09 points, well ahead of second place Ildar Gainullin.[14][15][16] Benjamin's two IOI wins made him only the fourth person ever to win multiples IOIs, and the first since Gennady Korotkevich won his 3rd IOI in 2011.[17]
USACO Problem setter
Following his high school graduation in 2019, Benjamin Qi became one of the lead problem writers for the USACO contest. As of April, 2021, he has contributed over two dozen problems to the contest.
Other competitions
Benjamin has reliably been in the top 10 in various competitive competitive programming websites. As of April 2021, he was the number 1 ranked coder on Codeforces with a rating of 3675, and the number 5 ranked coder on Atcoder with a rating of 3683.[18] He finished 2nd place in the 2020 Facebook Hacker Cup.[19] He finished 6th place in the 2020 Google Code Jam.[20] He was a finalist at the virtual 2020 Topcoder Open.[21]
Educational Initiatives
Benjamin has been actively involved in increasing the recognition of competitive programming within the United States.
USACO Guide
As part of his Competitive Programming Initiative, Benjamin created the USACO Guide in June 2020. Its stated purpose is be a "comprehensive, organized roadmap carefully designed and crafted for USACO contestants – available to everyone, for free."[5] On his Github account, Benjamin also has a repository with hundreds of solutions to past USACO problems.[22]
