In its original form the Manta Carlo technique was devised in order to handle with stationary states. The proper introduction of the time variable in the Monte Carlo scheme in order to use it in the framework of diffusion studies, is the purpose of this article. With reference to the jump theory we
Implicit Monte Carlo (IMC) is often employed to numerically simulate radiative transfer. In problems with regions that are characterized by a small mean free path, IMC can take a prohibitive amount of time, because many particle steps must be simulated to advance the particle through the time step.
Diffusion Monte Carlo (DMC) is a random walk computational method for solving the ground-state Schrodinger equation for atoms or molecules. One obtains a biased simulated energy which is used to estimate the exact energy, where the bias increases with the time step used in the simulation. We present
