摘要: Aging phenomena are observed in many spin class experiments. Heuristic state space models were presented the past to reproduce these effects. We here start investigation by considering real of an Ising glass Hamiltonian. A branch-and-bound algorithm is used find low-energy part space. solve problem still huge size employing a special coarse-graining algorithm. The system can be reduced computational treatable size. demonstrate that systems contain all properties necessary for aging
