Abstract

The ground state energy of the +-J 2-dimensional square and 3-dimensional cubic spin glasses are determined by the Genetic Algorithm. System sizes of linear dimensions 6 to 20 are considered in 2-dimensions and from 4 to 9 in 3-dimensions. We estimate that the ground state energy of the infinite system is -1.400 +-0.005 (2d) and -1.765 +-0.01 (3d) in units of J.
