标题： The Rational Hybrid Monte Carlo Algorithm

摘要： 近年来，在生成包含动力费米子效应的规范场的算法开发方面取得了显著进展。 有理混合蒙特卡洛（RHMC）算法是这些发展之一，在该算法中，混合蒙特卡洛通过使用有理逼近来替代通常的逆夸克矩阵核来进行。 该算法被发现在格点QCD的许多领域（手征费米子、有限温度、威尔逊费米子等）中极为有益。 我们回顾了该算法及其一些益处，并将其与其他最近的算法发展进行了比较。 最后，我们更新了柏林墙图，对比了所有流行的费米子形式的成本。 显示英文摘要

摘要： The past few years have seen considerable progress in algorithmic development for the generation of gauge fields including the effects of dynamical fermions. The Rational Hybrid Monte Carlo (RHMC) algorithm, where Hybrid Monte Carlo is performed using a rational approximation in place the usual inverse quark matrix kernel is one of these developments. This algorithm has been found to be extremely beneficial in many areas of lattice QCD (chiral fermions, finite temperature, Wilson fermions etc.). We review the algorithm and some of these benefits, and we compare against other recent algorithm developements. We conclude with an update of the Berlin wall plot comparing costs of all popular fermion formulations.
