Who first showed in 1979 that linear programming can be solved in polynomial time?
AGeorge Dantzig
BNarendra Karmarkar
CLeonid Kantorovich
DLeonid Khachiyan
Answer & Solution
Correct answer: D. Leonid Khachiyan
Leonid Khachiyan proved polynomial-time solvability in 1979, before Karmarkar's 1984 interior-point method.
