\subsection{Testing}
To test the theories learned, load \texttt{test.pl} with
\begin{verbatim}
?:- use_module(library('cplint/test')).
\end{verbatim}
and call
\begin{verbatim}
?:- main([<stem_fold1>,...,<stem_foldn>],[<testing_set_fold1>,...,

For example, if you want to test the theory in \verb|ai_train.rules| on the set \verb|ai.kb|, you can call
\begin{verbatim}
?:- main([ai_train],[ai]).
\end{verbatim}
The testing program has the following parameter:
\begin{itemize}
\item \verb|neg_ex| (values: \verb|given|, \verb|cw|, default value: \verb|cw|): if set to \verb|given|, the negative examples
are taken from \verb|<testing_set_foldi>.kb|, i.e., those example \verb|ex| stored as \verb|neg(ex)|; if set to \verb|cw|, the negative examples are generated according to the closed world assumption, i.e., all atoms for target predicates that are not positive examples. The set of all atoms is obtained by collecting the set of constants for each type of the arguments of the target predicate.
\end{itemize}
\subsection{Learning Examples}
The subfolders \verb|em|, \verb|rib|, \verb|slipcase| and \verb|slipcover| of the \verb|packages/cplint| folder in Yap git distribution
contain examples of input and output files for the learning algorithms.
