A method for global minimization of nonconvex quadratic functions
Adil Bagirov, Vivek Laha, Juan Enrique Martínez-Legaz
The problem of global minimization of nonconvex quadratic functions subject to box constraints is studied. Applying Gershgorin theorem we reduce the main matrix A to its diagonal f…

Hybrid subgradient and simulated annealing method for hemivariational inequalities
Piotr Bartman-Szwarc, Adil M. Bagirov, Anna Ochal
In this paper, we employ a global aggregate subgradient method for the numerical solution of hemivariational inequality problems arising in contact mechanics. The method integrates…

A truncated epsilon-subdifferential method for global DC optimization
Adil M. Bagirov, Kaisa Joki, Marko M. Makela +1
We consider the difference of convex (DC) optimization problem subject to box constraints. Utilizing epsilon-subdifferentials of DC components of the objective, we develop a new me…
