Abstract

We present an exact algorithm for finding all the ground states of the two-dimensional Edwards-Anderson ±J\pm J spin glass and characterize its performance. We investigate how the ground states change with increasing system size and and with increasing antiferromagnetic bond ratio xx. We find that that some system properties have very large and strongly non-Gaussian variations between realizations.
