Accelerated sampling using SamAdams variable timesteps and position-adaptive Langevin dynamics

Benedict Leimkuhler, Peter A. Whalley

We introduce an accelerated Langevin-based sampling method that is based on two complementary devices: \emph{SamAdams} adaptive timestepping, which automatically shrinks the effective integration step in stiff regions of phase space using a relaxed stiffness monitor, and \emph{po…Read more
