Convergence analysis of M-iteration for 𝒢-nonexpansive mappings with directed graphs applicable in image deblurring and signal recovering problems

Demonstratio Mathematica, 2023
In this article, weak and strong convergence theorems of the M-iteration method for 𝒢-nonexpansive mapping in a uniformly convex Banach space with a directed graph were established.

A Dai-Liao-type projection method for monotone nonlinear equations and signal processing

Demonstratio Mathematica, 2022
In this article, inspired by the projection technique of Solodov and Svaiter, we exploit the simple structure, low memory requirement, and good convergence properties of the mixed conjugate gradient method of Stanimirović et al.

Equilibrium of a production economy with non-compact attainable allocations set

Advances in Nonlinear Analysis, 2018
In this paper, we consider a production economy with an unbounded attainable set where the consumers may have non-complete non-transitive preferences.

Signal recovery and polynomiographic visualization of modified Noor iteration of operators with property (E)

Demonstratio Mathematica
This article aims to provide a modified Noor iterative scheme to approximate the fixed points of generalized nonexpansive mappings with property (EE) called MN-iteration.

A globally convergent algorithm for MPCC

EURO Journal on Computational Optimization, 2015
We propose a penalty formulation based on the new regularization scheme for mathematical programs with complementarity constraints (MPCCs). We present an active set method which solves a sequence of penalty-regularized problems.

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

EURO 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.

On the construction of quadratic models for derivative-free trust-region algorithms

EURO Journal on Computational Optimization, 2017
We consider derivative-free trust-region algorithms based on sampling approaches for convex constrained problems and discuss two conditions on the quadratic models for ensuring their global convergence.
