A continuous Newton-type method for unconstrained optimization

, 2008
In this paper, we propose a continuous Newton-type method in the form of an ordinary differential equation by combining the negative gradient and Newton’s direction.

On the finite termination of an entropy function based smoothing Newton method for vertical linear complementarity problems

By using a smooth entropy function to approximate the non-smooth max-type function, a vertical linear complementarity problem (VLCP) can be treated as a family of parameterized smooth equations.

Inexact Newton-type Methods for Optimisation with Nonnegativity Constraints

We consider solving large scale nonconvex optimisation problems with nonnegativity constraints. Such problems arise frequently in machine learning, such as nonnegative least-squares, nonnegative matrix factorisation, as well as problems with sparsity-inducing regularisation.

ADAPTED SOLUTION WITH NEWTON-KANTOROVICH METHOD FOR NONLINEAR VOLTERRA INTEGRAL EQUATIONS

, 2019
[[abstract]]Find an approximate solution is one of the most important problems in our days, in this paper we look for an approximate solution for Volterra nonlinear integral equation using a combination between Newton-Kantorovich method and adapted ...

Newton Leaves and the Continuous Newton Method

, 1993
Aspects of the continuous Newton method in IR n are discussed from a viewpoint of global optimization. Using an algebraic instead of an analytic definition of Newton trajectories we generalize the usual concept to certain higher dimensional sets ...
