Optimal steepest descent algorithms for unconstrained convex problems: fine tuning Nesterov’s method
We modify the first order algorithm for convex programming proposed by Nesterov. The resulting algorithm keeps the optimal complexity obtained by Nesterov with no need of a known Lipschitz constant for the gradient, and performs better in practically all examples in a set of test problems.
