- "Temporal and Spatial Constraint
- Propagation Management"
-
- The problems of plan generation (PG) and the problems of plan execution
- monitoring (PEM), including updating, answering queries, and resource-
- bounded replanning, have different computational, reasoning and representa-
- tion requirements. This proposal is for work that focuses on the computa-
- tional constraints of dynamic problems such as PEM for large scale, real
- world problems. We present a hierarchy based model of spatial and temporal
- constraints useful for application to such problems. The focus of this work
- is to address the computational restrictions on constraint propagation
- necessary for anytime performance. Control of propagation through a
- structured hierarchy of locally compiled and cached constraints is presented.
- Local consistency and explicit relations are preserved while global
- consistency and relations are subject to effects of limited propagation. A
- preliminary implementation, using MATS as the temporal reasoner, will be
- described.
