本文研究了一种避免混合蒙特卡罗方法及相关算法中的拒绝现象的方法——额外机会广义混合蒙特卡罗方法。本着延迟拒绝的精神,无论何时出现拒绝,都要做额外的工作,以找到一个有望被接受的新提案。我们提出的实验清楚地表明,在额外机会方法中进行的每个样本的额外工作在生成样本的质量方面显然是值得的。
We study a method, Extra Chance Generalized Hybrid Monte Carlo, to avoid rejections in the Hybrid Monte Carlo method and related algorithms. In the spirit of delayed rejection, whenever a rejection would occur, extra work is done to find a fresh proposal that, hopefully, may be accepted. We present experiments that clearly indicate that the additional work per sample carried out in the extra chance approach clearly pays in terms of the quality of the samples generated.
