Researchers have accumulated much evidence on the impor- tance of appropriate representations for the efficiency of AI systems. The same problem may be easy or difficult, dependi

Abstractiontruct a solution outline that ignores less significant aspects, and use it to guide the search for a complete solution. The applications of this approach take different shapes, and their utility varies widely across systems and domains. The related analytical models give disparate efficiency predict

Statistical selectionon (Section 7.1), derive a solution to this problem (Sections 7.2 and 7.3), use it in choosing a representation (Sections 7.4), and give empirical results that confirm the effectiveness of the selection algorithm (Sections 7.5 and 7.6).
