We study the overrelaxation algorithm developed by one of us (S.A.) for the SU(2) gauge theory in four dimensions. We find improvement in the decorrelation time for the plaquette by a factor of 2 to 3. However, our results suggest that the Monte Carlo application of overrelaxation behaves quite differently from the classical differential-equation analog. In particular, the optimum value of the overrelaxation parameter ..omega.. may depend on what order parameter one measures. In addition, there are order parameters that do not appear to improve by overrelaxation.
