AFOSR-sponsored research completed during 1989 and 1990 has advanced the basic understanding of the structure of tasks in problem solving and how method selection can occur within knowledge based problem solving systems. The important notion of task-structure, providing a means of characterizing the relation of task, method, and subtask, aids in the construction of large, complex, and versatile systems. The analysis of the design task provides a good illustration of task structure methodology. Complexity analysis complement our understanding of the computational resource requirements of various cases of central solving tasks.
