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
Forward state-space planners using greedy regression heuristic are competitive with the best available planners
- At this time, there do not seem to be comparably effective heuristics for plan-space planners.
Plan-space planners still provide better support for incremental planning (replanning, reuse and plan modification)
