摘要：We apply the UV-filtering preconditioner, previously used to improve the Multi-Boson algorithm,
to the Polynomial Hybrid Monte Carlo (UV-PHMC) algorithm. The performance test for the
algorithm is given for the plaquette gauge action and the O(a)-improved Wilson action at b =
5.2,csw = 2.02,Mp /Mr » 0.8 and 0.7 on a 163×48 lattice. We find that the UV-filtering reduces
the magnitude of the molecular dynamics force from the pseudo fermion by a factor 3 by tuning
the UV-filter parameter. Combining with the multi-time scale molecular dynamics integrator we
achieve a factor 2 improvement.
