# MCMC2 (version 1.1): A Monte Carlo code for multiply-charged clusters

## Description

Abstract This new version of the MCMC^2program for modeling the thermodynamic and structural properties of multiply-charged clusters by means of parallel classical Monte Carlo methods provides some enhancements and corrections to the earlier version [1]. In particular, histograms for negatively and positively charged particles are separated, parallel Monte Carlo simulations can be performed by attempting exchanges between all the replica pairs and not only one randomly chosen pair, a new random numb...
