The evidence for systematic errors that occur due to linear congruential random number generators and the diagnosis of their origin were presented. The implementation of Swendsen-Wang algorithms was also modified to eliminate these systematic errors. The errors arised from correlations within a single bond-update half-sweep. They can be eliminated by updating the bonds in a random order or in aperiodic manner.
