Computational time assessment of the FSP method vs balanced reduction approach.

<p>Comparison of the computational time required to obtain the reduced order model via balanced realisation (filled circle) and to obtain the approximative model via the FSP method (empty markers), with different, predefined error bounds (). The reaction network analysed is (28). The parameters used for simulation are those of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0103521#pone-0103521-g003" target="_blank">Figure 3</a>. Panels , , and consider 10, 30, and 50 initial molecules for <i>E</i> and <i>S</i> and zero molecules for the rest of the species, respectively.
