Where does guidance come from?
Learned from (planning) experience
- EBL-based search control rule learning
- inductive learning
- Case-based reasoning (DerSNLP)
Given by humans (often, they are quite willing!)
- As declarative rules (HTN Schemas, Tlplan rules)
- Don’t need to know how the planner works..
- Tend to be hard rules rather than soft preferences…
- Whether or not a specific form of knowledge can be exploited by a planner depends on the type of knowledge and the type of planner
- As procedures (SHOP)
- Direct the planner’s search alternative by alternative..
