  • 3. Reasoning: Goal Trees and Rule-Based Expert Systems

    Reporting on a Goal Tree program A Goal Tree program can answer questions about its own behavior by reporting steps up (why questions) or down (how questions) in the actions it takes. Simon’s Ant The complexity of a program’s behavior is a consequence of the environment, not the complexity of the program. Complexity (behavior) =…

  • 2. Reasoning: Goal Trees and Problem Solving

    Problem reduction Take a complicate problem and transform it into a simpler problem. Start with safe transformations, the ones you are sure will work in any case. Then apply heuristic transformations, the ones that could work. The problem simplification schema, may create “and node“, where the problem forks in several sub problems and “or node”…
