A structure for systems that plan abstractly
Walter Jacobs · 1971
The advantages of introducing planning procedures in systems that deal with complex tasks are generally recognized. Here the special benefits of using abstraction in the planning process will be considered, and a structure particularly well suited for abstract planning, the purposive system, will be described. An example will be presented to show how abstract planning operates under the purposive system; this is the program PERCY, which simulates the behavior of a nest-building insect.
