论文摘要
我们构建了用于哈密顿（或混合）蒙特卡洛采样的集成剂。新的集成商很容易实现，对于给定的计算预算，可以提供五倍的接受提案，而不是标准的Leapfrog/Verlet而不会以任何方式损害样品的质量。它们基于J.C. Butcher首先引入的处理技术的适当修改。修改处理的想法也可能对其他目的有用，例如构建具有正系数的高阶分裂积分器。
We construct integrators to be used in Hamiltonian (or Hybrid) Monte Carlo sampling. The new integrators are easily implementable and, for a given computational budget, may deliver five times as many accepted proposals as standard leapfrog/Verlet without impairing in any way the quality of the samples. They are based on a suitable modification of the processing technique first introduced by J.C. Butcher. The idea of modified processing may also be useful for other purposes, like the construction of high-order splitting integrators with positive coefficients.
