Figure 2: Interim output from Clavier simulation on Police Artist task. The target pattern is displayed on the right. The output of the current cycle is displayed on the left. The cycle number is displayed beneath the output. The Hamming distance (the number of mismatched pixels between the two images) is displayed above and between the output and target. Since the simulation displays the output only when the difference between output and target is less than for any previous output, the 1136th output is only the 12th display, with a difference of six pixels.
