Can anyone point me to some source code for monte carlo methods for free energy estimation. Standard metropolis/hamiltonian dont work since its the integral not the expectation I'm interested in.(adsbygoogle = window.adsbygoogle || []).push({});

candidates seem to be path sampling/ bridge sampling and annealed importance sampling of which anealed importance sampling seems to be the best.

However I cant quite understand the algorithm from Neal's paper

http://www.cs.toronto.edu/~radford/ais-pub.abstract.html

So does anyone know of any source code/pseudo code or even just a good expination of what the algorithm is?
