a, The time evolution of actuators with (blue) and without (black) the AI control. Possible tearing stability limits are indicated in red. b, The tearability expected by actuators' control. c, The normalized plasma pressure expected by actuators' control. d, The expected plasma evolution by the desired AI control in parametric space.
