Figure 2

Algorithm performance for a range of perturbations, with 5% of 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 good runs, "×" represents poor runs and "" represents helped 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 . For all the runs represented in those plots, 5% of the genes were pre-set to be constant.
