Increasing the number of transcription factors increases the complexity and decreases
robustness. We trace the steady state attractors of 1000 random networks with 100 nodes and 246
edges each (preserving the node-edge ratio of the E.coli network) where the number of TFs have been varied from 5 to 90 for 100 random initial
conditions and report the number of attractors (plot a) and size of the largest attractor (plot b) against the number of transcription factor in the system. As we increase the number
of TFs, the number of attractor (and the variance) increases and the size of largest
attractor (and the variance) decreases.We also plot knockout (plot c) and initial condition robustness (plot d), in terms of SRR values, of these networks. Both knockout and initial condition
robustness are strongly affected by the number of attractors, although the trend is
stronger for the initial condition robustness.
