Cluster-flipping Monte Carlo algorithm and correlations in "good" random number generators
Selke W. , Talapov A. L. , Shchur L. N.
Monte Carlo simulations of the two-dimensional Ising model at criticality are performed using the cluster-flipping Wolff algorithm. Correlations found recently in a widely used "good" random number generator are observed to depend strongly and systematically on the size of the Monte Carlo system. Rather long-range correlations seem to cause trouble, in growing clusters of specific size in a biased way.
