Fuzzy LogicAbstractThis article provides a general overview of the theory of fuzzy logic. Describes the concepts of fuzzy sets and the operations used in their manipulation, developed by Lofti Zadeh in 1965. The article provides examples of applications of fuzzy logic, with emphasis on the field of artificial intelligence. Fuzzy Logic"When Theseus returned from killing the Minotaur, Plutarch says, the Athenians preserved his ship and, as the planks rotted, replaced them with new ones. When the first plank was replaced, everyone agreed that it was still the same ship. the Athenians could have replaced every plank of the ship. Was it a different ship? At what point did it become one? [1]Questions of this kind have bothered people familiar with classical logic for centuries logical preposition must be completely true or false, does not seem to meet the expectations of today's very technical and logic-dependent world However, most computer engineers, control systems engineers and many other people involved in behavior modeling and programming do still rely on True/False conditions and differential equations. Many people tried to adapt classical logic to accept a broader concept of something being true or false. In the early 1900s, Lukasiewicz presented his three-valued logic, where the proposed third value could be described as "possible", and had a numerical value between True and False [2]. His efforts were followed by Knuth, but neither idea gained widespread acceptance. It wasn't until 1965, when Lotfi Zadeh published his work on fuzzy sets and the mathematics that accompanied them. The theory quickly with... half of the article......trol, Peter Bauer, Stephan Nouak, Roman Winkler, 1996, (http://www.flll.uni-linz.ac.at/fuzzy /fuzzy .html) References: Fuzzy Logic Research and Life, Japanese Technology Evaluation Center, 1995, (http://itri.loyola.edu/kb/c5_s4.htm) Two responses to Elkan's paper, Enrique Ruspini, 1993, (http: //www-cgi.cs.cmu.edu/afs/cs/project/ai-repository/ai/areas/fuzzy/doc/elkan/response.txt)Fuzzy Logic Primer - A brief introduction to fuzzy logic, Togai InfraLogic Inc ., 1992, (http://www-cgi.cs.cmu.edu/afs/cs/project/ai-repository/ai/areas/fuzzy/doc/intro/primer.tgz)The Seven Noble Truths of Fuzzy Logic , Earl Cox, 1992, (http://freeware.aus.sps.mot.com/freeweb/pub/fuzzy/news5.txt) Creating a Fuzzy Expert System, William Siler, http://members.aol.com / wsiler/index.html) The Logic of the Future, Earl Cox, http://darwin1.ucsd.edu:8000/connect/articles/success/logic.html)
