摘要Using the convex process theory we study the convergence issues of the iterative sequences generated by the Gauss-Newton method for the convex inclusion problem defined by a cone C and a Fréchet differentiable function F (the derivative is denoted by F’ ). The restriction in our consideration is minimal and, even in the classical case (the initial point x_0 is assumed to satisfy the following two conditions: F’ is Lipschitz around x_0 and the convex process T_{x_0} , defined by T_{x_0} = F’ (x_0) ● −C, is surjective), our results are new in giving sufficient conditions (which are weaker than the known ones) ensuring the convergence of the iterative sequence with initial point x_0. When F is analytic, we study point estimate conditions similar to Smale's conditions for nonlinear analytic equations. The same study is also made for the so-called convex-composite optimization problem (with objective function given as the composite of a convex function with a Fréchet differentiable map).
