Stochastic simulation Boltzmann distribution

A last increasingly popular family of MC simulations, not to be confused with the Metropolis method, exploits sampling from non-Boltzmann distributions to simulate kinetic events which are extremely rare compared to the typical molecular timescales, e.g., as is the case of charge transfer (dynamic or Kinetic MC [105], KMC) or reactive events (Gillespie s stochastic simulation algorithm [106]).
