In chemistry, dynamic Monte Carlo (DMC) is a Monte Carlo method for modeling the dynamic behaviors of molecules by comparing the rates of individual steps with random numbers.
Unlike the Metropolis Monte Carlo method, which has been employed to study systems at equilibrium, the DMC method is used to investigate non-equilibrium systems such as a reaction, diffusion, and so-forth (Meng and Weinberg 1994).
Although the FRM and RSM give the same results from a given model, the computer resources are different depending on the applied system.
The RSM decides whether the reaction of the selected molecule proceeds or not by comparing the transition probability with a random number.
In this method, the reaction does not necessarily proceed in one event, so it needs significantly more computation time than FRM.
