 We have tested a variety of potential objectives for the SimpPleAC model, some of which are as follows:
 \begin{itemize}
-    \item $W_f$: Fuel weight, the default objective in the ```main``` method.
+    \item $W_f$: Fuel weight, the default objective.
     \item $W$: Total aircraft weight. Like fuel weight, but also adding extra cost for airframe weight.
     \item $D$: Drag. 
     \item $\frac{W_f}{T_{flight}}$: Product of the fuel weight and the inverse of the time of flight.
