The Wumpus Advisor program offers advice to a player involved in choosing the best move in a game for which competence in dealing with incomplete and uncertain knowledge is required. The design and implementation of the advisor explores a new paradigm in Computer Assisted Instruction, in which the performance of computer-based tutors is greatly improved through the application of Artificial Intelligence techniques. This report describes the design of the Advisor and outlines directions for further work. Our experience with the tutor is informal and psychological experimentation remains to be done.
