曲面存在下自回避行走的切割置换算法
Cut-and-permute algorithm for self-avoiding walks in the presence of surfaces
摘要:
我们提出了一个动态的非局部混合蒙特卡罗算法,包括主元和“切割和置换”移动。该算法适用于研究聚合物的非线性几何在普通的过渡,枢轴算法表现出准遍历问题。在d = 3的情况下研究了该算法的动态特性。混合动力学是遍历的,并表现出相同的最佳临界行为的枢轴算法在散装。
英文摘要:
We present a dynamic nonlocal hybrid Monte Carlo algorithm consisting of pivot and ``cut-and-permute'' moves. The algorithm is suitable for the study of polymers in semiconfined geometries at the ordinary transition, where the pivot algorithm exhibits quasi-ergodic problems. The dynamic properties of the proposed algorithm are studied in d = 3. The hybrid dynamics is ergodic and exhibits the same optimal critical behavior as the pivot algorithm in the bulk.
