Optimizing the diffusion coefficient of overdamped Langevin dynamics
Tony Lelièvre, Grigorios A. Pavliotis, Geneviève Robin +2
Overdamped Langevin dynamics are reversible stochastic differential equations which are commonly used to sample probability measures in high-dimensional spaces, such as the ones ap…
