Abstract:
I study a simple variation of the algorithm of Metropolis et al. for simulating statistical systems. The trial changes in any given variable are taken from a region of phase space far from the old value but involving only small changes in energy. This results in correlation times which are short com- pared to the usual applications of the algorithm of Metropolis et al. Tests with SU(2) and SU(3) lat- tice gauge theories indicate substantial possible savings in computation time relative to standard ap- proaches.
