Limited memory discrete gradient bundle method for nonsmooth derivative-free optimization

, 2012
Typically, practical nonsmooth optimization problems involve functions with hundreds of variables. Moreover, there are many practical problems where the computation of even one subgradient is either a difficult or an impossible task.

A Distributed Primal-Dual Framework for Composite Optimization with Nonseparable Coupled NonSmooth Function

Mathematical and Computational Applications
This paper investigates a distributed convex optimization problem whose objective contains three terms: a local smooth convex function, a local nonsmooth function, and a globally shared, possibly nonsmooth, nonseparable coupling function.

State Estimation and Tracking Control of Saturation Sandwich Systems Based on Particle Swarm Optimization

IEEE Access
This paper proposes an integrated control framework combining a nonsmooth observer and a switching feedback law to address the state estimation and tracking control challenges of sandwich systems with saturation nonlinearities.

A two-point heuristic to calculate the stepsize in subgradient method with application to a network design problem

EURO Journal on Computational Optimization
We introduce a heuristic rule for calculating the stepsize in the subgradient method for unconstrained convex nonsmooth optimization which, unlike the classic approach, is based on retaining some information from previous iteration.

Certificates of infeasibility via nonsmooth optimization

, 2016
An important aspect in the solution process of constraint satisfaction problems is to identify exclusion boxes which are boxes that do not contain feasible points.

Variational Optimality Conditions with Feedback Descent Controls that Strengthen the Maximum Principle

Известия Иркутского государственного университета: Серия "Математика", 2014
We derive nonlocal necessary optimality conditions that strengthen both classical and nonsmooth Maximum Principles for nonlinear optimal control problems with free right-hand end of trajectories.

Optimization problems with quasiconvex inequality constraints [PDF]

The constrained optimization problem min f(x), gj(x) 0 (j = 1, . . . , p) is considered, where f : X ! R and gj : X ! R are nonsmooth functions with domain X Rn.
