Abstract
We test globally corrected hybrid updating algorithms for various lattice theories: a chain of coupled harmonic oscillators, pure SU(3) theory, and QCD with four flavors of dynamical staggered quarks. Systematic errors, acceptance, and time correlations are studied as functions of discretization step size, momentum refreshing frequency, volume, coupling and fermion-matrix-inversion residue.Keywords
