Consider gradient-based Markov chain Monte Carlo methods, including Hamiltonian Monte Carlo (HMC), applied to rough energy landscapes. Generic-gradient-stiffness conjecture. The we…

Let $V$ be a potential admitting a decomposition of the type referred to in the source, and let approximate or smoothed energy landscapes be used to construct proposals for samplin…

Let an independence sampler target a distribution on $n$ coordinates, and consider a Metropolis-within-Gibbs sampler in which only a subset of those coordinates is altered at each…
