July 2004

As work slowed down for the summer, and inspired by the thriving interactive fiction (IF) community detailed in last month’s newsletter, I decided to spend more time on interactive fiction (IF) tools, so that’s what this newsletter is about. In one sense, its a specialized application area, but the issues with IF tools apply to other areas of AI as well, such as: pitfalls with “intelligent” interfaces; when to use rules versus when to use objects; and how to augment logic for a particular application area....

Fantasy Games Adventure was the first computer fantasy game. It had all of the elements we see today in Nintendo and Play Station fantasy games, where the computer has a model of an environment and the player manipulates a character in the game, travelling from place to place, encountering various challenges and puzzles along the way, collecting points for challenges met, and in general being entertained by unfolding story line and discovered scenarios....

Interactive Web-Based Experts Like all computer programs, expert systems take input, process it, and provide output. For example, an expert system might input symptoms and output a diagnosis; input customer requirements and output a product configuration; or input a robot’s situation and output an action.

Notes The diagrams that were supposed to appear in the last two month’s newsletters didn’t display on most people’s systems. The newsletters are archived at an alternate site, www.ainewsletter.com, that has copies of the issues with the pictures. This month’s newsletter has some further applications of the fuzzy logic system developed in the February newsletter. Contact me to get the the latest version of the fuzzy logic system and the full source for this month’s examples....

February 2004

The February 2004 newsletter is really a companion piece for the January 2004 newsletter. January discussed fuzzy logic and its usefulness for control systems, and included discussions of some simple examples. This month’s newsletter has the code used for the experiments in January. It is a fuzzy logic laboratory intended for modification and experimentation. The full code for the system is included in the newsletter, but if you are interested in getting the files directly, send me an e-mail....
