Free energy estimation (Monte Carlo)

  1. Jan 5, 2005 #1
    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.

    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

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