Global convergence via descent modified three-term conjugate gradient projection algorithm with applications to signal recovery

open access: yesResults in Applied Mathematics, 2019
In this article, we propose a three-term conjugate gradient projection algorithm for solving constrained monotone nonlinear equations. The global convergence of the algorithm was established under suitable assumptions.

A new convergence proof for the higher-order power method and generalizations [PDF]

open access: yes, 2015
A proof for the point-wise convergence of the factors in the higher-order power method for tensors towards a critical point is given. It is obtained by applying established results from the theory of \L{}ojasiewicz inequalities to the equivalent ...

A comparison of four approaches from stochastic programming for large-scale unit-commitment

open access: yesEURO Journal on Computational Optimization, 2017
In energy management, the unit-commitment problem deals with computing the most cost-efficient production schedule that meets customer load, while satisfying the operational constraints of the units.

Interiors of completely positive cones [PDF]

open access: yes, 2014
A symmetric matrix $A$ is completely positive (CP) if there exists an entrywise nonnegative matrix $B$ such that $A = BB^T$. We characterize the interior of the CP cone.

PONTRYAGIN PRINCIPLES IN INFINITE HORIZON IN PRESENCE OF ASYMPTOTICAL CONSTRAINTS

open access: yes, 2015
We establish necessary conditions of optimality for discrete-time infinite-horizon optimal control in presence of constraints at infinity. These necessary conditions are in form of weak and strong Pontryagin principles.

On the rate of convergence of the proximal alternating linearized minimization algorithm for convex problems

open access: yesEURO Journal on Computational Optimization, 2016
We analyze the proximal alternating linearized minimization algorithm (PALM) for solving non-smooth convex minimization problems where the objective function is a sum of a smooth convex function and block separable non-smooth extended real-valued convex ...

Improving the linear relaxation of maximum k-cut with semidefinite-based constraints

open access: yesEURO Journal on Computational Optimization, 2019
We consider the maximum k-cut problem that involves partitioning the vertex set of a graph into k subsets such that the sum of the weights of the edges joining vertices in different subsets is maximized.

Discrete time pontryagin principles in banach spaces

open access: yes, 2017
The aim of this paper is to establish Pontryagin's principles in a dicrete-time infinite-horizon setting when the state variables and the control variables belong to infinite dimensional Banach spaces. In comparison with previous results on this question,
