Exploring constraint qualification-free optimality conditions for linear second-order cone programming
Autor: Olga Kostyukova, Tatiana Tchemisova
Publikováno v: An International Journal of Optimization and Control: Theories & Applications, Vol 14, Iss 3 (2024)
Linear second-order cone programming (SOCP) deals with optimization problems characterized by a linear objective function and a feasible region defined by linear equalities and second-order cone constraints. These constraints involve the norm of a li

Regularization Algorithms for Linear Copositive Programming Problems: An Approach Based on the Concept of Immobile Indices
Autor: Olga Kostyukova, Tatiana Tchemisova
Publikováno v: Algorithms, Vol 15, Iss 2, p 59 (2022)
In this paper, we continue an earlier study of the regularization procedures of linear copositive problems and present new algorithms that can be considered as modifications of the algorithm described in our previous publication, which is based on th
