摘要翻译:
采用路径交换的方法可以大大提高路径采样仿真的效率。为此,我们设计了一种新的基于过渡界面采样技术的算法程序。在同样的平行锤炼的精神下,不同系综之间的路径是互换的,但温度的作用在这里由界面位置发挥。我们用Peyrard-Bishop-Dauxois模型对DNA变性转变的方法进行了测试。我们发现新算法的计算量减少了20倍。

英文摘要:
The efficiency of path sampling simulations can be improved considerably using the approach of path swapping. For this purpose, we have devised a new algorithmic procedure based on the transition interface sampling technique. In the same spirit of parallel tempering, paths between different ensembles are swapped, but the role of temperature is here played by the interface position. We have tested the method on the denaturation transition of DNA using the Peyrard-Bishop-Dauxois model. We find that the new algorithm gives a reduction of the computational cost by a factor 20.
