Abstract
A Monte Carlo method for obtaining exact ground-state properties of a class of Hubbard Hamiltonians is described. Results are presented for two special cases, nearest-neighbor Coulomb and on-site interactions, where previous exact results are known. The straightforward applicability of the method to a wider variety of interactions is demonstrated.Keywords
