Generalized 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 کاملHybrid Monte Carlo Without
We introduce a dynamical fermion algorithm which is based on the hybrid Monte Carlo (HMC) algorithm, but without pseudofermions. The molecular dynamics steps in HMC are retained except the derivatives with respect to the gauge elds are calculated with the Z2 noise. The determinant ratios are estimated with the Pa de Z2 method. Finally, we use the Kennedy-Kuti linear accept/reject method for the...
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.
