+
+NOTE: this should provide a higher-level overview of the written code:
+
+\begin{itemize}
+    \item State machine (which functions call when).
+    \item Algorithmic complexity.
+    \item Expected runtime given the number of bends/vertices, some performance
+        experiments.

 \section{Results of Experiments}
 
 NOTE: this can only be filled after the algorithm implementation is complete.
