(cid:863, machines are programmed to demonstrate human intelligence in problem solving and decision making. Artificial intelligence techniques: search- many different search algorithms exist. Implement one or more mental processes for both study and application purposes: visual perception or image recognition, language processing and, 1. find how humans do it. 4. communication, problem solving and decision support, motor movement. A case is defined by disease symptoms and paired with treatments, a case is the characteristics of a problem on a device and the corresponding solution. Expert system: employs knowledge (facts); logic (rules, primarily in the form of an if-then structure) and algorithms or procedure for searching and choosing rules. Search in artificial intelligence: blind searches contain no information about the layout of the problem space.
