Noisy Monte Carlo algorithm reexamined
Abstract
We present an exact Monte Carlo algorithm designed to sample theories where the energy is a sum of many couplings of decreasing strength. Our algorithm, simplified from that of Lin, Liu, and Sloan, avoids the computation of almost all nonleading terms. We illustrate its use by simulating SU(2) lattice gauge theory with a five-loop action, and discuss further applications to full QCD.
