Truncated Log-concave Sampling with Reflective Hamiltonian Monte Carlo

1 code implementation25 Feb 2021 Apostolos Chalkis, Vissarion Fisikopoulos, Marios Papachristou, Elias Tsigaridas

We introduce Reflective Hamiltonian Monte Carlo (ReHMC), an HMC-based algorithm, to sample from a log-concave distribution restricted to a convex body.
