Distribution of triangle areas and number of triangles per cellular process. a. The area of a gene's triangle is a proxy for its impact on phenotype and fitness. For each run, the genes of the final best individual were binned into area classes. The red (resp. green) bar plot is the average of the four distributions obtained from the final best individuals of the four runs where k = 750 (resp. k = 250). b. Distribution of the number of triangles per cellular process for the best individual of one simulation with k = 750 in red and one simulation with k = 250 in green. Under relaxed selection, the number of triangles per process is reduced.
