A robust Kantorovich's theorem on inexact Newton method with relative residual error tolerance

O. P. Ferreira, B. F. Svaiter

We prove that under semi-local assumptions, the inexact Newton method with a fixed relative residual error tolerance converges Q-linearly to a zero of the non-linear operator under…

Convergence of the Gauss-Newton method for convex composite optimization under a majorant condition

Orizon Perreira Ferreira, Max Leandro Nobre Gonçalves, Paulo Roberto Oliveira

Under the hypothesis that an initial point is a quasi-regular point, we use a majorant condition to present a new semi-local convergence analysis of an extension of the Gauss-Newto…
