+The generic_rk module is an attempt to modularize solvers for ordinary differential equations (ODEs).

+Below is the result of an example problem known as the Brusselator using an adaptive timestep control. The first subplot shows the raw results of $y_1$ and $y_2$ within the range $t \in [0, 20]$. The second subplot shows the acceptable $dt$ used throughout the simulation.

+\begin{array}{r l}
+y_1' &=& 1 + y_1^2 y_2 -4y_1 \\
+y_2' &=& 3y_1 - y_1^2 y_2 \\
+\end{array}

+$$ y_1(0) = 1.5, ~~~ y_2(0) = 3, ~~~ t \in [0, 20]$$
