Query: A comparison of updating algorithms for large N reduced models   We investigate Monte Carlo updating algorithms for simulating $SU(N)$
Yang-Mills fields on a single-site lattice, such as for the Twisted
Eguchi-Kawai model (TEK). We show that performing only over-relaxation (OR)
updates of the gauge links is a valid simulation algorithm for the Fabricius
and Haan formulation of this model, and that this decorrelates observables
faster than using heat-bath updates. We consider two different methods of
implementing the OR update: either updating the whole $SU(N)$ matrix at once,
or iterating through $SU(2)$ subgroups of the $SU(N)$ matrix, we find the same
critical exponent in both cases, and only a slight difference between the two.
