The Relationship between the Noise Amplitude <i>σ</i> and the Growth Rate <i>v_g</i>

<p>Starting from randomly chosen initial conditions against the noise amplitude <i>σ</i> ranging 10⁻⁴ < <i>σ <</i>3, the growth rates <i>v_g</i> after 10⁵ time steps are plotted. In the intermediate range <i>σ</i> of the noise strength 10⁻² < <i>σ <</i>1, cellular states with high growth rates are selected among a huge number of possible cellular states, as depicted in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.0040003#pcbi-0040003-g002" target="_blank">Figure 2</a>.
