The Stillinger-Lovett ion pairing procedure was adapted to allow for the association of multivalent cations iwth their counterions and combined it with the reservoir grand canonical Monte Carlo method of Errington and Panagiotopoulos. By doing so, they were able to significantly increase the acceptance rates of the simulations which resulted in the CPU time to be proportional to Q2 rather than exp(Q). This allows to extend the study of the critical behavior of asymmetric electrolytes beyond a charge asymmetry of 3:1, which was not possible using only the distance bias method, and to try to corroborate the predictions of Linse et al.
