Leonid Genrikhovich Khachiyan[1][a] (/kɑːtʃiːən/;[4] Russian: Леони́д Ге́нрихович Хачия́н; May 3, 1952 – April 29, 2005) was a Soviet and American mathematician and computer scientist.
He was most famous for his ellipsoid algorithm (1979) for linear programming,[5] which was the first such algorithm known to have a polynomial running time. Even though this algorithm was shown to be impractical, it has inspired other randomized algorithms for convex programming and is considered a significant theoretical breakthrough.
