The complexity of linear programming
A. H. G. Rinnooy-Kan, Jan Telgen · Statistica Neerlandica · 1981
Abstract The simplex method for linear programming has always been very successful from a practical point of view. In the worst case, however, the method may require a computational effort that increases exponentially with problem size. Recently L.G. Khachianproposed an entirely different solution method whose running time is bounded by a polynomial function of problem size, thereby settling a major open problem in computational complexity theory. We review the developments preceding Khachian's discovery, describe the algorithm and discuss its implications.
