MYCIN was developed at Stanford University as an expert system to aid in the diagnosis of bacterial meningitis. The difference between an expert system with a normal problem-solving system is that the latter is a system where both programs and data structures are encoded, while for expert system only the data structures are hard-coded and no problem-specific information is encoded in the program structure. The savings produced by XCON has convinced DEC management that artificial intelligence, particularly its application to expert systems, has a bright future. MYCIN: This was one of the earliest expert systems that was based on backward chaining. In addition to this information, the editors had information indicating which components can or must be associated with other components. But one, MYCIN, most clearly introduced two essential characteristics of an expert system: modularity and justification. Once a sample’s chemical formula is known, the chemist may use the sample’s mass spectrogram to work out the way the atoms are arranged in the chemical’s structure, thus identifying the isomer of the chemical. The examples are: 1. Let’s call the first significant organism from this culture U1. This section focuses on "Expert System" in Artificial Intelligence. Fixed freeze() with frozen objects. Those decisions are accurate and prefect by considering specific set of rules. For example, there are expert systems that can diagnose human illnesses, make financial forecasts, and schedule routes for delivery vehicles. The tester compares the real mass spectrogram with those produced by the generator. Loan departments are interested in expert systems for mortgages because of the growing cost of labor which makes the handling and acceptance of relatively small loans less profitable. It could also recommend drugs based on the patient's weight. There are numerous examples of expert systems.
