Case-study: DerSNLP
Modifiable derivational traces are reused
Traces are automatically acquired during problem solving
- Analyze the interactions among the parts of a plan, and store plans for non-interacting subgoals separately
- Use of EBL failure analysis to detect interactions
All relevant trace fragments are retrieved and replayed before the control is given to from-scratch planner
- Extension failures are traced to individual replayed traces, and their storage indices are modified appropriately
- Improves retrieval accuracy
