Makoto Soejima (副島 真, Soejima Makoto, born 1991) is a Japanese former competitive programmer.[1] He is one of three people to have won both the Google Code Jam and the Facebook Hacker Cup and the only one to have also won a gold medal with a perfect score at the International Mathematical Olympiad (IMO).[1][2][3][4] In International Science Olympiads, he has won three gold medals and one bronze in the International Mathematical Olympiad as well as two silver medals in the International Olympiad in Informatics (IOI).[1][4][5]
Biography
[edit]Soejima was born in 1991.[2] He began competitive programming in 1999.[5] He attended Junior and Senior High School at Komaba, University of Tsukuba.[6] During his time at high school, he participated in the IMO multiple times (2005, 2007–2009) where he obtained three gold medals and one bronze.[3][4][6] On his final attempt in 2009, he achieved a perfect score.[3][6] At the same time, Soejima also participated in the 2008 and 2009 IOI where he obtained a silver medal both times.[1][6]
Soejima then attended The University of Tokyo where he studied mathematics.[6] He was part of the university team in the 2013 and 2015 International Collegiate Programming Contest which won third place both times.[1] Soejima also attended the Graduate School of Information Science and Technology at The University of Tokyo.[7]
Soejima's other significant achievements in competitive programming include winning the 2011 Google Code Jam, winning the 2016 Facebook Hacker Cup, and being Topcoder Open Algorithm champion in 2010, 2011 and 2016.[1][4]
In December 2020, Soejima retired from competitive programming.[5][8] By 2021 Soejima worked at AtCoder, a company that organizes programming competitions.[5][8][4]
