To obtain algorithms for these problems, we make the use of abstract interpretation techniques which provide over-approximations of the transitions set to be disabled. To our knowledge, with the hypotheses taken, the improved version of our algorithm provides a better solution than what was previously proposed in the literature. Our tool SMACS allowed us to make an empirical validation of our methods to show their feasibility and usability %U http://www.irisa.fr/vertecs/Publis/Ps/2009-ecc-control.pdf %8 August %D 2009
