FiatLux is a discrete dynamical systems simulator that allows the user to experiment with various models and to perturb them. It includes 1D and 2D cellular automata, moving agents, interacting particle systems, etc. Its main feature is to allow users to change the type of updating, for example from a deterministic parallel updating to an asynchronous random updating. FiatLux has a Graphical User Interface and can also be launched in a batch mode for the experiments that require statistics.

FiatLux is registered by the Agence pour la protection des programmes (APP). It is available under the CeCILL licence on the FiatLux website :

In 2014, FiatLux was internally re-shaped in order to facilitate the reproducibility of experiments. In particular, attention was given to the generation of pseudo-random sequences for the stochastic models.
