Sacerdoti, E. D. (1981). Problem solving tactics. AI Magazine, 2(1), 7-7.
This paper describes the basic strategies of automatic problem solving, and then focuses on a variety of tactics for improving their efficiency. An attempt is made to provide some perspective on and structure to the set of tactics. Finally, some new directions for problem-solving research are discussed, and a personal perspective is provided on where the work is headed: toward greater flexibility of control and more intimate integration of plan generation, execution, and repair.
