Tuning the hybrid Monte Carlo algorithm.
We apply the Hybrid Monte Carlo Algorithm to pure gauge QCD and to QCD with 4 flavors of staggered dynamical fermions. We show how the acceptance in the global Metropolis step depends upon the parameters of the algorithm. By tuning the values of the coupling constants in the algorithm to be different from those in the global Metropolis step, we find that the acceptance can be kept large without...
متن کاملGeneralized Hybrid Monte Carlo
One of the most demanding calculations is to generate random samples from a specified probability distribution (usually with an unknown normalizing prefactor) in a high-dimensional configuration space. One often has to resort to using a Markov chain Monte Carlo method, which converges only in the limit to the prescribed distribution. Such methods typically inch through configuration space step ...
متن کاملGeneralized Hybrid Monte-carlo
We propose a modification of the Hybrid Monte-Carlo method to sample equilibrium distributions of continuous field models. The method allows an efficient implementation of Fourier acceleration and is shown to reduce completely critical slowing down for the Gaussian model, i. e., z = 0.
