Stochastic simulations

[dnavarrocueto]

Hi,

I've been using MOLUSCE to simulate land uses. I wonder how does the software perform the cellular automata simulations. If I'm right the land use transitions are based on a 'potential transition value', calculated via any transition model implemented, for each cell which is a probability to change to another land use. So I would expect each time the simulation is run it gets slightly different results based on the potential transitions, but I get always the same results.

Does the software perform any kind of mean of the results? Or is it implementing a deterministic algorithm? And the main question, is it possible to simulate different results based on the potential transition values?

Cheers

Dani
