The Graves Theorem Revisited II: Robust Convergence of the Newton Method [PDF]

open access: yes, 1998
AMS subject classification: 65J15, 47H04, 90C30.Based on the original proof of the Graves theorem [9] we study the convergence of the Newton method for the solution of the equation f (x) = y, uniform with respect to the starting point and the parameter y.

Joint minimization with alternating Bregman proximity operators

open access: yes, 2006
International audienceA systematic study of the proximity properties of Bregman distances is carried out. This investigation leads to the introduction of a new type of proximity operator which complements the usual Bregman proximity operator.

Second order optimality conditions in nonsmooth unconstrained optimization. [PDF]

open access: yes, 1998
AMS subject classification: 49J52, 90C30.Second order sufficient and necessary conditions are given for a nonsmooth function f defined in a Banach space to attain a minimum at a point in the interior of its domain.

Finding a Strict Feasible Dual Initial Solution for Quadratic Semidefinite Programming

open access: yes, 2012
In this paper, we propose an algorithm to comput the dual initial feasible solution for solving a primal-dual optimization problem (convex quadratic semidefinite programming) by a interior point methods.

Comments on “A Note on the Paper “Optimality Conditions for Optimistic Bilevel Programming Problem Using Convexifactors””

open access: yes
Necessary optimality conditions for a bilevel optimization problem are given in the paper by Kohli (J Optim Theory Appl 152: 632–651, 2012). Recently, the same author corrected his results in the note (J Optim Theory Appl 181:706–707, 2019). In this work,

A new multisection technique in interval methods for global optimization

open access: yes, 2000
A new multisection technique in interval methods for global optimization is investigated, and numerical tests demonstrate that the e ciency of the underlying global optimization method can be improved substantially.
