Subgradient Smoothing Method for Nonsmooth Nonconvex Optimization

open access: yes, 2021
In this chapter an unconstrained nonsmooth nonconvex optimization problem is considered and a method for solving this problem is developed. In this method the subproblem for finding search directions is reduced to the unconstrained minimization of a ...

On Switching Times Optimization and Second‐Order Sufficient Conditions for Optimal Bang‐Bang Boundary Control of the Heat Equation

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT We consider optimal control of the heat equation where the control variable appears linearly as a boundary control. We establish switching times optimization for bang–bang controls with multiple switching times. Particularly, representations of variational derivatives of the state and the cost w.r.t. switching times are given.

Subgradient and bundle methods for nonsmooth optimization

open access: yes, 2013
The nonsmooth optimization methods can mainly be divided into two groups: subgradient and bundle methods. Usually, when developing new algorithms and testing them, the comparison is made between similar kinds of methods.

A Smoothing Method with Appropriate Parameter Control Based on Fischer-Burmeister Function for Second-Order Cone Complementarity Problems

open access: yesAbstract and Applied Analysis, 2013
We deal with complementarity problems over second-order cones. The complementarity problem is an important class of problems in the real world and involves many optimization problems.

Distributed stochastic nonsmooth nonconvex optimization

open access: yesOperations Research Letters, 2022
Distributed consensus optimization has received considerable attention in recent years; several distributed consensus-based algorithms have been proposed for (nonsmooth) convex and (smooth) nonconvex objective functions. However, the behavior of these distributed algorithms on {\it nonconvex, nonsmooth and stochastic} objective functions is not ...

An Adaptive Multiple Shooting Strategy for Optimal Control

open access: yesOptimal Control Applications and Methods, Volume 47, Issue 6, Page 1453-1471, November/December 2026.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.
