Where 'Ignoring Delete Lists' Works: Local Search Topology in Planning Benchmarks
2005
The Journal of Artificial Intelligence Research
Preserved Fulltext
Other Versions
The key technique behind this progress is the use of heuristic functions based on relaxing the planning task at hand, where the relaxation is to assume that all delete lists are empty. ...
We *prove* connections between domain structure and local search topology -- heuristic cost surface properties -- under an idealized version of the heuristic functions used in modern planners. ...

The ignoring delete lists relaxation is of paramount importance for both satisficing and optimal planning. ...
In earlier work, it was observed that the optimal relaxation heuristic h+ has amazing qualities in many classical planning benchmarks, in particular pertaining to the complete absence of local minima. ...
This raises the question what h + actually is, in finite-domain variable planning, where there are no "delete lists". That question is easily answered. ...

Despite recent progress in AI planning, many benchmarks remain challenging for current planners. ...
As shown before, FF computes this heuristic by solving a relaxed planning problem (i.e., the delete effects of actions are ignored) in a graphplan framework. ...
