Leonid Levin
contemporaryPhilosophy of Mathematics, Computational Complexity Theoryb. 1948
Leonid Levin (born 1948) is a Soviet-American computer scientist and mathematician at Boston University, best known for independently co-discovering NP-completeness alongside Stephen Cook. His work bridges computational complexity, algorithmic information theory, and the philosophical foundations of mathematics, with particular attention to the limits of formal systems and the epistemological status of mathematical knowledge.
