Online Hamiltonian Monte Carlo Demo
(formerly known as `Hybrid Monte Carlo')
Task: sample from the posterior distribution of a bivariate Gaussian
distribution given ten data points.
The left-hand image shows the details underlying a sequence of
HMC transitions. The right-hand image shows 50 of the successive states
produced by the Markov chain - the endpoints of the trajectories.

There is also an introductory
that explains Hamiltonian Monte Carlo
and contrasts it with the Metropolis method,
using the same "strongly-correlated Gaussian"
example as is used in the
Adler Overrelaxation demo.
