Figure 4.

Changes in population distribution beyond the error threshold for different values of Kq. Part A. Hamming class distribution beyond the error threshold for different values of Kq. All the distributions have been obtained for q = 0.8. The population for Kq = 1 is the uniform distribution obtained in classical error catastrophe (see text for details). For a greater or lesser value of Kq, the population is displaced to nearest or farther Hamming classes, respectively. Part B. Average Hamming distance as a function of 1-q, for different values of Kq. The changes in Kq does not modify the error threshold, but the average Hamming distance at the error catastrophe is modified as a consequence of the displacement of the population showed in part A of the figure.
