Therefore, a match is -represented as a tree of moves. The state of the board at any given move must -also be stored so liberties, captures count and legality of moves can be -addressed, so it is represented with its own class, which holds a reference both -to the game tree and the current move. Moves depend on a representation of the -game board to have access to its current layout and count of captured stones. -These classes and their relationships can be seen in -\fref{fig:gameRepresentation}. - -\begin{figure}[h] - \begin{center} - \includegraphics[width=0.7\textwidth]{diagrams/gameRepresentation.png} - \caption{A game is represented as a tree of moves.}\label{fig:gameRepresentation} - \end{center} -\end{figure} - -\subsection{SGF} - -To parse SGF files a lexer and parser have been implemented using PLY.\@ The -result of the parsing is an AST (Annotated Syntax Tree) reflecting the contents -of the text input, each node with zero or more properties, and with the ability -to convert themselves and their corresponding subtree into a GameTree.
