摘要翻译:
经典系综中复杂系统的传统模拟存在拟遍历性问题。广义系综中的模拟克服了这一困难,在势能空间和其他参数空间中进行随机游动。通过单直方图和/或多直方图加权技术,只需一次模拟,就可以得到物理量作为温度函数的正则系综平均值。本文综述了广义集成算法。首先介绍了三种常用的算法,即多点算法、模拟回火法和副本交换法。文中给出了蒙特卡罗算法和分子动力学算法。然后,我们给出了上述三种方法的进一步扩展。

英文摘要:
Conventional simulations of complex systems in the canonical ensemble suffer from the quasi-ergodicity problem. A simulation in generalized ensemble overcomes this difficulty by performing a random walk in potential energy space and other parameter space. From only one simulation run, one can obtain canonical-ensemble averages of physical quantities as functions of temperature by the single-histogram and/or multiple-histogram reweighting techniques. In this article we review the generalized-ensemble algorithms. Three well-known methods, namely, multicanonical algorithm, simulated tempering, and replica-exchange method, are described first. Both Monte Carlo and molecular dynamics versions of the algorithms are given. We then present further extensions of the above three methods.
