WitrynaIn this paper, we present a Newton-type iterative method that shares many properties of Picard-type iterative methods, namely it is derivative-free and does not use inverse operators, although preserving the quadratic order of convergence that characterizes Newton’s method. These features allow us to design an efficient iterative method. Witryna1 lis 2024 · Nesterov Y Accelerating the cubic regularization of Newton’s method on convex problems Math.
