Fast convex optimization via inertial dynamics with Hessian driven damping

We first study the fast minimization properties of the trajectories of the second-order evolution equationx¨(t)+αtx˙(t)+β∇2Φ(x(t))x˙(t)+∇Φ(x(t))=0, where Φ:H→R is a smooth convex function acting on a real Hilbert space H, and α, β are positive parameters. This inertial system combines an isotropic v...
