A pattern database (PDB) stores shortest distances from abstract states to a set of abstract goal states. For many search problems the best heuristic function is obtained using PDBs. We aim to find optimal solutions for Sokoban using PDBs. Due to the domain-specific characteristics of the goal states a straightforward application of PDBs ...More
