Time rescaling of a primal-dual dynamical system with asymptotically vanishing damping
David Alexander Hulett, Dang-Khoa Nguyen
In this work, we approach the minimization of a continuously differentiable convex function under linear equality constraints by a second-order dynamical system with an asymptotica…
Fast convex optimization via time scale and averaging of the steepest descent
Hedy Attouch, Radu Ioan Bot, Dang-Khoa Nguyen
In a Hilbert setting, we develop a gradient-based dynamic approach for fast solving convex optimization problems. By applying time scaling, averaging, and perturbation techniques t…
Fast Krasnosel'skii-Mann algorithm with a convergence rate of the fixed point iteration of
Radu Ioan Bot, Dang-Khoa Nguyen
The Krasnosel'skii-Mann (KM) algorithm is the most fundamental iterative scheme designed to find a fixed point of an averaged operator in the framework of a real Hilbert space, sin…
Fast Optimistic Gradient Descent Ascent (OGDA) method in continuous and discrete time
Radu Ioan Bot, Ernö Robert Csetnek, Dang-Khoa Nguyen
In the framework of real Hilbert spaces we study continuous in time dynamics as well as numerical algorithms for the problem of approaching the set of zeros of a single-valued mono…
