Structured Planning and Debugging: A Linguistic Theory of Design
Unknown author (1976-12-01)
A unified theory of planning an debugging is explored by designing a problem solving program called PATN. PATN uses an augmented transition network (ATN) to represent a broad range of planning techniques, including identification, decomposition, and reformulation. (The ATN [Woods 1970] is a simple yet powerful formalism which has been effectively utilized in computational linguistics.)
