摘要：The effectiveness of various dilution schemes in the evaluation of baryonic two-point functions is
compared. The error of a representative set of observables as a function of the number of Dirac
matrix inversions is used as a basis for comparison. To achieve an equivalent reduction in error,
we demonstrate that an increase in the number of dilution projectors on a single noise source
usually requires fewer inversions than the use of multiple noise sources. This exploratory study
was performed on 100 quenched gauge configurations and will be applied to the calculation of
low-lying hadron spectra.
