(color online) Numerical estimating results. (a) Successful clicking rate of the presented protocol as a function of the noise rate B. Here, c = 0, corresponding to the worst case, is chosen as a better sample to make a comparison with the SLAZ protocol. The solid (dash–dot) curve is plotted for M = 25 (50). (b) Successful clicking rate of the SLAZ2013 protocol as a function of the noise rate B. The solid (dash–dot) curve is plotted for M = 25 (50), N = 320 (1250).
