摘　　要：采用模拟退火法并借助二维伊辛模型研究了自旋玻璃的基态问题,使得这类问题的计算量大大缩减,同时也得到了相当准确的系统基态能量值,并对系统基态的状态进行了分析.By use of an algorithm called simulated annealing, the problem of ground states of spin glass is studied based on the twodimensional Ising model. The calculating results show that this method can gratly reduce the calculation and give precise energies of the ground states. In addition, the spining distribution of the ground states for amultipartical system is analyzed by this method.
