摘要：

Large numbers of ground states of three-dimensional (3D) Edwards-Anderson Ising spin glasses are calculated for sizes up to 10(3) using a combination of a genetic algorithm and cluster-exact approximation. A detailed analysis shows that hue ground states are obtained. The ground-state stiffness (or domain wall) energy Delta is calculated. A \Delta\similar to L(Theta)s behavior with Theta(s)=0.19(2) is found that strongly indicates that the 3D model has an equilibrium spin-glas a-paramagnet transition for nonzero T-c.
