The Isomerization of Alpha-Pinene problem tries to determine "reaction coefficients in the thermal isometrization of 
-Pinene." (Cite and problem taken from the COPS library)
Mathematical formulation
The problem is given by
![\begin{array}{llcl}
\displaystyle \min_{\theta} &\sum\limits_{j=1}^{8} &&||y(\tau_j; \theta) - z_j||^2 \\[1.5ex]
\mbox{s.t.}
& \dot{y}_1 & = & -(\theta_1 + \theta_2) y_1, \\
& \dot{y}_2 & = & \theta_1 y_1, \\
& \dot{y}_3 & = & \theta_2 y_1 - (\theta_3 + \theta_4) y_3 + \theta_5 y_5, \\
& \dot{y}_4 & = & \theta_3 y_3, \\
& \dot{y}_5 & = & \theta_4 y_3 - \theta_5 y_5, \\
& \theta_i & \geq & 0.
\end{array}](https://mintoc.de/images/math/6/3/5/635e0acc7a448aa68d8ee3cc7dd6f359.png)
Parameters
The values 
are measurements for the concentration for 
at time points 
and initial conditions are known.
