Tutorial Project Evolutions

Written by Victor Yukhtenko. Email: victor@pdc.spb.su

This is an example of Visual Prolog project development evolution beginning from the initial idea till the today status. A very easy game has been chosen as the basic idea. We do not know the initial name of this game so we call it Polyline.

Each release expands the functionality of the application. Moving along the way the code is extended, modified and restructured or only restructured and modified.

Game description

The game is played on an M x N board.

Game rules

• Each player on his turn adds a new point. The point must prolong the existing Polyline (or start the Polyline, if it doesn't exist).
• The resulting Polyline must be non-interrupted and each move can be taken in any of end of the line.
• The player, which locks the line (the point is set on the polyline), wins.
