Figure 4From: Biological sequences as pictures – a generic two dimensional solution for iterated mapsImproved map coverage by the proposed solution when compared with that of Fiser and co-workers. The relative coverage is calculated as (1-s2)/(1-s1), where s1 is the solution by Equation 1 and s2 is the proposed solution, by Equation 2. At regular increments of 4 in the length of the alphabet (number of vertices) the two solutions are equivalent, as discussed in the text.Back to article page
