Plan Execution: Problems and Issues: Papers from the AAAI Fall Symposium
Louise Pryor, Chair
Traditionally, work on planning has concentrated on how plans can be constructed, but as the planning community has begun to address more complex, real-world problems, the issues surrounding the execution of plans have come to the fore. Systems are being built that construct plans that are used in domains ranging from robot navigation to image processing and information retrieval. Such systems must often be able to handle actions with duration, simultaneous execution of actions, plans with conditionals and loops, and plan failure. These new demands on an agent require considerable extensions to the classical model of plans as simple sequences of actions guaranteed to achieve their goals.
The program included sessions consisting of presentations of two or three papers on a common theme, comments by a designated commentator, and open discussion; panel presentations followed by open discussion; poster presentations; and demonstrations of implemented systems. Themes included the role of deliberation in execution-based systems, the role of execution in deliberation-based systems, matching domain characteristics and architectures, multi-agent systems, the uses of formalism; and much more.
