A new LQP alternating direction method for solving variational inequality problems with separable structure
Bnouhachem, Abdellah; Hamdi, Abdelouahed; Xu, M. H. ( Taylor and Francis Ltd. , 2016 , Article)We presented a new logarithmic-quadratic proximal alternating direction scheme for the separable constrained convex programming problem. The predictor is obtained by solving series of related systems of non-linear equations ... -
An algorithm approach to maximal monotone operators and pseudo-contractions
Zhu, Xinhe; Yao, Zhangsong; Hamdi, Abdelouahed ( International Scientific Research Publications , 2016 , Article)The purpose of this article is to find the minimum norm solution of maximal monotone operators and strict pseudo-contractions in Hilbert spaces. A parallel algorithm is constructed. Some analysis techniques are used to ... -

On Indefinite Quadratic Optimization over the Intersection of Balls and Linear Constraints
Almaadeed, Temadher; Karbasy, Saeid Ansary; Salahi, Maziar; Hamdi, Abdelouahed ( Springer , 2022 , Article)In this paper, we study the minimization of an indefinite quadratic function over theintersection of balls and linear inequality constraints (QOBL). Using the hyperplanesinduced by the intersection of each pair of balls, ... -
Parallel LQP alternating direction method for solving variational inequality problems with separable structure
Bnouhachem, Abdellah; Hamdi, Abdelouahed ( Springer International Publishing , 2014 , Article)In this paper, we propose a logarithmic-quadratic proximal alternating direction method for structured variational inequalities. The predictor is obtained by solving series of related systems of nonlinear equations, and ... -
Portfolio Selection Problem Using CVaR Risk Measures Equipped with DEA, PSO, and ICA Algorithms
Hamdi, Abdelouahed; Karimi, Arezou; Mehrdoust, Farshid; Belhaouari, Samir Brahim ( MDPI , 2022 , Article)Investors always pay attention to the two factors of return and risk in portfolio optimization. There are different metrics for the calculation of the risk factor, among which the most important one is the Conditional ...
