摘要我们提出了多点Metropolis算法,作为Frenkel和Smit的方向偏向蒙特卡罗算法的扩展。引入了类似于Metropolis算法中的比率统计来维持详细的平衡。多点思想可以应用于提高一般的基于马尔可夫链的蒙特卡罗算法的效率。为了说明这一点,我们描述了这一思想的两种变体--随机网格大都会和多点混合蒙特卡罗--并将它们应用于许多例子。
Abstract We propose the multipoint Metropolis algorithm as an extension of the orientational-bias Monte Carlo of Frenkel and Smit. A ratio statistics similar to that in the Metropolis algorithm is introduced to maintain the detailed balance. The multipoint idea can be applied to improve the efficiency of a general Markov chain-based Monte Carlo algorithm. To illustrate, we describe two variations of the idea—the random-grid Metropolis and the multipoint Hybrid Monte Carlo—and apply them to a number of examples.
