RT Journal Article T1 A multisite microcanonical updating method A1 Cruz, A. A1 Fernández Pérez, Luis Antonio A1 Íñiguez, D. A1 Tarancón, A. AB We have made a study of several update algorithms using the XY model. We find that sequential local overrelaxation is not ergodic at the scale of typical Monte Carlo simulation time. We have introduced a new multisite microcanonical update method, which yields results compatible with those of random overrelaxation and the microcanonical demon algorithm, which are very much slower, all being incompatible with the sequential overrelaxation results.
