Global convergence of the Heavy-ball method for convex optimization
Euhanna Ghadimi, Hamid Reza Feyzmahdavian, Mikael Johansson
This paper establishes global convergence and provides global bounds of the convergence rate of the Heavy-ball method for convex optimization problems. When the objective function…
Sub-homogeneous positive monotone systems are insensitive to heterogeneous time-varying delays
Hamid Reza Feyzmahdavian, Themistoklis Charalambous, Mikael Johansson
We show that a sub-homogeneous positive monotone system with bounded heterogeneous time-varying delays is globally asymptotically stable if and only if the corresponding delay-free…
Asymptotic Stability and Decay Rates of Homogeneous Positive Systems With Bounded and Unbounded Delays
Hamid Reza Feyzmahdavian, Themistoklis Charalambous, Mikael Johansson
There are several results on the stability of nonlinear positive systems in the presence of time delays. However, most of them assume that the delays are constant. This paper consi…
