Adler 过度松弛热浴算法的晶格规范理论推广和过度松弛 Metropolis 更新被证明可以加速物理可观测量的去相关。热浴的微规范极限尤其有吸引力。例如，纯规范 SU(3)（${4}^{4}$ 晶格，\ensuremath{\beta}=5.6）的数值测试表明，过度松弛将 Cabibbo-Marinari 算法的 Polyakov 环幅度自相关时间从 28 次扫描减少到 9 次，计算效率提高了三倍。这些方法适用于一大类物理系统。
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) (${4}^{4}$ lattice, \ensuremath{\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.
