Overrelaxed heat-bath and Metropolis algorithms for accelerating pure gauge Monte Carlo calculations

Journal Article · · Phys. Rev. Lett.; (United States)
The lattice-gauge-theory generalization of Adler's over-relaxed heat-bath algorithm and an over-relaxed Metropolis update are shown to accelerate the decorrelation of physical observables. The heat-bath's microcanonical limit is especially attractive. Numerical tests for pure gauge SU(3) (4/sup 4/ lattice, ..beta.. = 5.6) show, for example, that over-relaxation reduces the Polyakov-loop magnitude autocorrelation time for the Cabibbo-Marinari algorithm from 28 sweeps to 9, increasing computational efficiency threefold. These approaches are applicable to a large class of physical systems.
