AS-BOX: Additional Sampling Method for Weighted Sum Problems with Box Constraints
Nataša Krejić, Nataša Krklec Jerinkić, Tijana Ostojić +1
A class of optimization problems characterized by a weighted finite-sum objective function subject to box constraints is considered. We propose a novel stochastic optimization meth…
A Hessian inversion-free exact second order method for distributed consensus optimization
Dusan Jakovetic, Natasa Krejic, Natasa Krklec Jerinkic
We consider a standard distributed consensus optimization problem where a set of agents connected over an undirected network minimize the sum of their individual local strongly con…
Exact Spectral-Like Gradient Method for Distributed Optimization
Dusan Jakovetic, Natasa Krejic, Natasa Krklec Jerinkic
Since the initial proposal in the late 80s, spectral gradient methods continue to receive significant attention, especially due to their excellent numerical performance on various…
