Rukia

Random Uniform walK In Automata

Rukia is a C++ library to generate paths (or traces) in automata according to a defined coverage criterion. Thus, it provides generic algorithms to count the number of elements to be covered, and generic algorithms to explore automata at random while ensuring a uniform distribution among those elements.

lgpl Rukia is a free software: see the Lesser GNU Public license (LGPL). So basically, this means that you are free to use it anywhere but you need to make available any modification you did.

Rukia is also deposited in the Agency for the protection of programs (APP):

To understand how to use the Rukia library, the simplest way is to download the archive and refer to the README file inside.

If you are still not convinced by the interest of using Rukia instead of classical (isotropic) random walks, please compare the results from our experiments. Even better, try it on your models and send me back your results.
