摘要：
The damage spreading technique is applied to +/- J and Gaussian Ising spin glasses and ferromagnets in dimensions 3 and 4. By comparing with established values for the ordering temperatures in the spin glasses, it is shown that an independent damage spreading criterion can be used to obtain a reliable estimate of T(g), as long as precautions are taken concerning size effects. The physical significance of the damage spreading parameter is discussed.
