Abstract. It is shown that a certain class of generalizations of over-relaxation algorithms is incapable to further reduce the dynamical exponent z below its standard over-relaxed value of z=1 approximately. Approximately means that the mean field value is one, while the true value can be somewhat different in certain dimensions. The generalizations are obtained by viewing over-relaxation as a slightly deformed deterministic algorithm and should, therefore, hold for Hybrid Monte Carlo algorithms as well.
