Abstract
We have measured the dynamical critical exponents for the
Swendsen-Wang and the Wolff cluster update algorithms, as well as a
number of variants of these algorithms, for the q=2 and q=3 Potts
models in two dimensions. We find that although the autocorrelation
lengths differ considerably between algorithms, the critical exponents
are the same.
