    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (388 KB)

    Expert systems for applications that include the creation of a least-cost design or plan will frequently need built-in search procedures. Sometimes optimizing cannot terminate soon enough, and satisficing methods must be used. Quicksearch is a set of techniques for quickly obtaining good, but not necessarily optimal, solutions. These techniques are very specialized. The author simplifies and gener... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (615 KB)

    The application of probabilistic reasoning in building a practical decision support system for servicing large physical systems is described. Certainty factors (CFs) with probabilistic semantics reduce both the representational and the computational complexities of probabilistic reasoning. When the modularity assumption is violated, however, their use results in counterintuitive beliefs. To overco... View full abstract»
