Valeri Ivanovich Vasiliev (Russian: Валерий Иванович Васильев ) (August 3, 1949 – April 19, 2012) was a Russian ice hockey defenceman, who competed for the USSR.
 An eight-time Soviet all-star, Vasiliev was captain of the national team, for which he played 13 years.

Vladimir Aleksandrovich Smirnov (1931–12 February 1996, <a href="">) was a Russian philosopher.

Anatoly Alexandrovitch Vasiliev (Russian: Анато́лий Алекса́ндрович Васи́льев ; born May 4, 1942, Penza Oblast) is a noted Russian theatre director and one of the leading European contemporary stage directors.
 He is artistic director of the Moscow Theatre "School of Dramatic Arts", Théâtre de l'Europe, and professor of drama in Lyon, France.
Nicolai Alexandrovich Vasiliev (Russian: Николай Александрович Васильев ), also Vasil'ev, Vassilieff, Wassilieff (11 July [O.S. 29 June] 1880 – December 31, 1940), was a Russian logician, philosopher, psychologist, poet.
 He was a forerunner of paraconsistent and multi-valued logics.
The Karatsuba algorithm is a fast multiplication algorithm.
 It was discovered by Anatoly Karatsuba in 1960 and published in 1962.
 It reduces the multiplication of two "n"-digit numbers to at most formula_1 single-digit multiplications in general (and exactly formula_2 when "n" is a power of 2).
 It is therefore faster than the classical algorithm, which requires "n" single-digit products.
 For example, the Karatsuba algorithm requires 3 = 59,049 single-digit multiplications to multiply two 1024-digit numbers ("n" = 1024 = 2), whereas the classical algorithm requires (2) = 1,048,576.
