Fit the double Monod model to the data shown in the plot. The sliders control the parameters of each single Monod model, and the double Monod model is the sum of the two single Monod models. The expression for a single Monod model is described by the following ODE: $$\frac{d S}{d t} = - \frac{\alpha S}{\beta + S}.$$ The parameters of this model are \(\alpha\), \(\beta\), and the inital condition \(S_0\).
