Václav Kotěšovec (* July 29 1956 Prague) is an International Grandmaster of the FIDE for Chess Compositions (IGM)[1], and world famous chess problem composer. Since 2010, he has been an International Judge of the FIDE for chess composition. He also devotes to programming and theoretical mathematics, especially the search for asymptotic formulas for sequences of integers. Contributes as an author and editor to the OEIS.
Chess Activity
He has been composing chess problems since the early 1970s, and has published over 3000 problems. About 750 his compositions have been awarded, of which more than 230 prizes (of which over 50 firsts), 70 of them have been placed in the FIDE Albums. In 2005, he received the title International Master of the FIDE for Chess Composition, five years later he became an International Judge of the FIDE for the twomovers, helpmates and fairy chess problems.[2]. At the 2019-2021 World Championship in Composing for Individuals (WCCI), he took 3rd place in the Fairies section.[3] [4]
As a judge, he judged more than a hundred composition tournaments, including the FIDE Albums. He published 18 chess and chess-mathematical publications[5], in the late 1980s he worked as an editor for Czech magazine Šachové umění. He is also the webmaster of website www.kotesovec.cz and the main creator of a database of scanned old chess problems literature. He is a tester of solving computer programs, he himself once created in the Czech Republic popular program VKSACH (in the eighties).
Mathematics
He published a number of articles mainly on combinatorics.[6]. His field of study is asymptotic formulas, generating functions, integer series and partitions. He has contributed to the OEIS (The On-Line Encyclopedia of Integer Sequences)[7] database, of which he is the editor-in-chief, since 2012 more than 17000 contributions.[8] His asymptotic formulas have been cited in over 60 articles on ArXiv.org.[9]
Life
He was born in the family of Václav Kotěšovec and Jarmila, born Šedivá. He is the grandson of Rudolf Šedivý, one of the political prisoners of the political processes of the 1950s in former Czechoslovakia. In the years 1979-1990, he worked as an independent software development worker. In the years 1990-2004, he devoted to the programming of single-chip microprocessors, mainly in assembler. He got married in September 2016; he has been living with his wife Ludmila Pachtová since 2004. He is a collector of mushrooms and an admirer of gardens.
