Abstract: This paper investigates fast first-order methods for nonconvex optimization, inspired by a second-order dynamical system with vanishing damping and strongly convex dry friction. By ...

To study fine touch, selecting samples based on how many mechanical instabilities they can form is more predictive than using the friction coefficient, which has been the default choice.

Reservoirs smooth out the natural ups and downs of water supply. When refilling stops, power generation, water delivery, and flood control all degrade at once. Dry conditions expose limits built into ...
