In his short life (36 years) he managed to leave an impressive body of work. I love his monograph on combinatorics. It was printed in Soviet Union under title "Комбинаторика для программистов". It came with Pascal code and contained a wide range of algorithms. It's written clearly and very "applied" in style.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6490051.post-2599389228620428622010-02-15T22:35:00.002-05:002010-02-16T23:00:18.114-05:00ФТТ-XIIt's 11th conference on solid states physics in Kazakhstan.
