The elements of order two are reflections $s_i$, whose action on $\Z$ is transitive. The coupling can be any function of the absolute difference $|i-j|$. Because random choice of reflection will almost always result in energy changes so large that the whole system is flipped, it is -better to select random reflections about integers close to the average state +better to select random reflections about integers or half-integers close to the average state of the system. A variant of the algorithm has been applied without a field +whose success relies both on this and on using nonzero $q$ \cite{evertz_stochastic_1991}. \section{Performance} |
