基于随机增长算法的稀有事件抽样

Rare event sampling with stochastic growth algorithms

T. Prellberg

摘要:

我们讨论均匀采样算法,是基于随机增长的方法,使用简单的晶格模型作为动机的聚合物的极端配置的采样。我们将展示如何一系列聪明的增强五十多年的老算法,Rosenbluth方法,导致了一个尖端的算法能够均匀抽样的平衡统计力学系统的聚合物的情况下,竞争的算法未能表现良好。例子从粘性表面附近的塌陷的均聚物到蛋白质折叠的模型。

英文摘要:

We discuss uniform sampling algorithms that are based on stochastic growth methods, using sampling of extreme configurations of polymers in simple lattice models as a motivation. We shall show how a series of clever enhancements to a fifty-odd year old algorithm, the Rosenbluth method, led to a cutting-edge algorithm capable of uniform sampling of equilibrium statistical mechanical systems of polymers in situations where competing algorithms failed to perform well. Examples range from collapsed homo-polymers near sticky surfaces to models of protein folding.
