Description
This is the fourth and final part of the video called "Intensive PROLOG" and it forms a bridge between the earlier introductory lessons about PROLOG and the more practical and difficult c...oncerns of building real and useful systems in PROLOG. Taking part are Malcolm Dixon and Frank Kriwaczek. For a real-life system, this part of the video looks at the Thomas Cook expert system for planning routes on the Autstralian Railway network. Of course real-life is not like example programs. The Thomas Cook program introduces depth-first and breadth-first searching, the use of "cut" to save memory, and the incorporation of expert knowledge. By the end of the video, the early example of route-finders used in parts one and two have been adapted to a working route-finder not dissimilar to the one actually used by Thomas Cook. The video closes with a commentary ny Frank Kriwaczek on whether the end program can be called an "expert system". The answer is left undecided since the follow-up written work covers just this topic. Note, this video is incorporated as part of a text and software package and also includes "Stop The Tape" points where problems set in the video must be attempted.
