Observation of Plasma Fluctuations,The Sokoban puzzle (see Section 3.7.2) is more difficult than the Machining Domain; it usually requires long search, and it includes unsolvable problems. In most cases, PRODIGY cannot find near-optimal solutions, and cost bounds may lead to gross inefficiency; hence, we use PRODIGY without cost limits.

Plasmas in Planetary Interiors,The . world is larger than the other domains; it includes ten object types and twenty-three operators (Figures 3.38-3.41). We have tested .. with two linear and one nonlinear gain functions (Figure 12.1).

https://doi.org/10.1007/b103882The last series of experiments is based on the Logistics Domain [Veloso, 1994], which includes eight object types, six operators, and two inference rules (Figure 3.43). We have experimented with three linear gain functions and three nonlinear functions (Figure 13.1).

Summary and extensionsWe have described techniques for reducing . search based on primary effects and abstraction. First, we have presented algorithms for the selection of primary effects, and given an analytical and empirical evaluation of the resulting search reduction. Second, we have extended Knoblock’s abstraction technique to the full domain language of .4.

Summary and extensionsWe have described statistical procedures for evaluating representations. We now outline heuristic rules for choosing representations (Section 9.1), and review the results of the work on ..’s top-level control (Section 9.2).

Machining DomainWe apply .. to the model of a machine shop described in Section 3.6.2. All problems in this domain are solvable, and they never cause a failure of PRODIGY search.
