Conjunctive vs. Disjunctive planners
Progress depends on the effectiveness of the heuristics for judging the goodness of a partial plan
Search control may be easier to articulate
Space consumption can be regulated
Better fit with mixed-initiative, incremental planning scenarios(?)
Space consumption is a big issue
- Creation and storage of disjunctive structures
- The AT&T benchmark experiments were done on a 8-gig RAM m/c!
- E.g. TLPlan beats disjunctive planners at 800-block problems…
Better integration with non-propositional reasoners (?)
Hybrid planners--Controlled splitting &
Search in the space of disjunctive plans
