These problems are related to the state avoidance problem where one must compute a controller which prevents the system from accessing a set of bad states and which is maximal for a defined criterion, based on inclusion of the set of states remaining reachable after the control. We focus our study on memoryless controllers %U http://www.irisa.fr/vertecs/Publis/Ps/icca2009.pdf %U http://dx.doi.org/10.1109/ICCA.2009.5410356 %8 December %D 2009
