MONTE-CARLO SIMULATION IN DIFFUSION STUDIES - TIME SCALE PROBLEMS

In its original form the Monte Carlo technique was devised in order to handle 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 subject of this article. With reference to jump theory the authors analyze the meaning of the various Monte Carlo schemes which have been used and propose a different algorithm of increasing efficiency which solves problems of diffusion in disordered media.
