摘要

在模拟退火优化方法中确定残余熵可以提供关于真实基态能量的有用信息。以一维伊辛自旋玻璃为例,残余熵与单自旋翻转稳定亚稳态的数目有关。剩余熵随逆冷却速率呈对数缓慢下降至零。在monte que la determination de l’entropie residuelle上,采用了一种基于优化模型的方法,采用了四种基于基本熵的信息实用程序。在一个一维空间里,我们的研究是正确的。L 'entropie residuelle est减轻非盟和政变的亚稳剩下的马厩par retournement d一个单独的自旋。熵残差与熵残差之间的对数关系为零,熵残差与熵残差之间的对数关系为零

Residual entropy and simulated annealing
Determining the residual entropy in the simulated annealing approach to optimization is shown to provide useful information on the true ground state energy. The one-dimensional Ising spin glass is studied to exemplify the procedure and in this case the residual entropy is related to the number of one-spin flip stable metastable states. The residual entropy decreases to zero only logarithmically slowly with the inverse cooling rate On montre que la determination de l'entropie residuelle, dans la methode d'optimisation par recuit simule, fournit des informations utiles sur l'etat fondamental vrai. On etudie un verre d'Ising a 1 dimension. L'entropie residuelle est reliee au nombre d'etats metastables qui restent stables par retournement d'un seul spin. L'entropie residuelle ne decroit que logarithmiquement vers zero avec le taux inverse de refroidissement
