Search in the space of conjunctive partial plans
- Disjunction split into the search space
- search guidance is nontrivial
- Solution extraction is trivial
Examples:
- STRIPS & Prodigy
- SNLP & UCPOP
- NONLIN & SIPE
- UNPOP & HSP
Search in the space of disjunctive partial plans
- Disjunction handled explicitly
- Solution extraction is non-trivial
Two classes of refinement planners
Both are based on the same
three refinement strategies
