Transient time for robust elementary cellular automata

Transient time, in number of time steps, for distinct Elementary Cellular Automata when subject to distinct synchrony rates. The plots show the transient time for ECA 4, 36, 72, 76, 94, 104, 108, 132, 164, 218, 222, and 232. Updating scheme: 1 - Perfect synchrony -- all cells are updated simultaneously and in parallel. 2 - $\alpha$-asynchrony -- at each time step, every cell is updated with an independent and equal probability alpha. 3 - $\kappa$-asynchrony -- Given a synchrony rate $\alpha$- , at each time step, $\kappa$ = 1/$\alpha$ updates are performed. For non-integer $\kappa$ = 1/$\alpha$, decimal values are probabilistically used for deciding between performing n or n + 1 intermediate updates. The resulting con guration is considered as the automaton's next stage. See "An Experimental Study of Noise and Asynchrony in Elementary Cellular Automata with Sampling Compensation".
