MCMC2 : A Monte Carlo code for multiply-charged clusters

The running time depends on the number of Monte Carlo steps, cluster size, and type of interactions selected (e.g., polarisation turned on or off, and method used for calculating the induced dipoles). Typically a complete simulation can last from a few tens of minutes or a few hours for small clusters (N≤100, not including polarisation interactions), to one week for large clusters (N≥1000 not including polarisation interactions), and several weeks for large clusters (N≥1000) when including polarisation interactions. A restart procedure has been implemented that enables a splitting of the simulation accumulation phase.
