Aleksandr Aleksandrovich Razborov (Russian: Алекса́ндр Алекса́ндрович Разбо́ров ; born February 16, 1963), sometimes known as Sasha Razborov, is a Soviet and Russian mathematician and computational theorist. Steven Rudich (born October 4, 1961) is a professor in the Carnegie Mellon School of Computer Science.  In 1994, he and Alexander Razborov proved that a large class of combinatorial arguments, dubbed natural proofs were unlikely to answer many of the important problems in computational complexity theory.  For this work, they were awarded the Gödel prize in 2007.  He also co-authored a paper demonstrating that all currently known NP-complete problems remain NP-complete even under AC or NC reductions. Pyotr Alexandrovich Yefremov (Russian: Пётр Александрович Ефремов , born November 17 (O.S., 2), 1830, Moscow, Russian Empire, - died January 8, 1908 [O.S.
