Figure 3From: zipHMMlib: a highly optimised HMM library exploiting repetitions in the input to speed up the forward algorithmNumber of pattern occurrences against the number of iterations performed. The number of occurrences of the most frequent pair of symbols plotted on a log-scale against the number of iterations performed of the preprocessing procedure on an alignment of the human and chimpanzee chromosome 1 encoded using the alphabet {0,1,2} for identical sites, differing sites or missing data, respectively.Back to article page
