Figure 3.

Algorithm performance for a range of perturbation, with no constant genes. This series of three plots illustrates the performance of the algorithm. Each run of the algorithm is represented by a symbol in all three plots. The symbol "×" represents poor runs. In all three plots, the horizontal axis gives the effective perturbation (the average of the absolute difference to 1 of all scaling mismatches k_a). The vertical axis in the top plot is the number of iterations required to reach convergence. In the second plot, we present the accuracy of the rescaling factors (11). In the bottom plot, the vertical axis gives the size of the final set U_m. This series of plots are obtained through the same process shown in Figure 2 except that no genes were forced to be constant. In this situation, the algorithm yields only poor results, there are no good runs.
