\subsection{Detailed Description}
Various functions for strongly typed tree-based Genetic Programming.
The St\-Parse\-Tree functions use the same {\bf eo\-Parse\-Tree}{\rm (p.\,\pageref{classeo_parse_tree})} class for the individual but now each node class must have two additional functions. \begin{itemize}
\item int type(void) which returns the return type of the node \item int type(int child) which returns the required type for child 0, 1 or 2\end{itemize}
Pruning strongly typed trees is not possible at the moment.
