Conjunctive planners: The State of the Art
Vanilla state-space (FSR/BSR) planners were known to be less efficient than vanilla plan-space planners
- Several research efforts concentrated on extending plan-space approaches to non-classical scenarios
However, State-space planners seem to have better heuristic support than plan-space planners at this time
- Distance-based heuristics seem particularly useful for state-space planners
But, plan-space planners are alleged to provide better support for incremental planning, durative actions etc.
- replanning, reuse and plan modification, temporal reasoning
Charge: Either develop effective approaches for replanning etc. in state-space planners or develop good heuristics for plan-space planners
