The history of AI can frame it in three stages: - Years 50-70: Romantic Era, Years 70-90: Pragmatics .- was 90-years now: It was Realista.Años: 1956 - Newell and Simon developed The Logic Theorist, considered by many the first program IA1957 - the first version is presented Program General troubleshooting. It aims to demonstrate any kind of problema.1958 - McCarthy creates language LISP (Listing Processing), considered a language of IAFinales 50 - Frank Rosemblatt, Perceptron, the first attempt to simulate the neural computation to perform the 60 tasks complejas.En - Joseph Weizembaum develops the Eliza program, considered the first system in the field of Language Processing Natural.1965 - It develops the first successful expert system DENDRAL, Stanford University, system oriented to the determination of the chemical structure of a compound and at MIT, developed the Macsyma, Expert System oriented to solving complex math problems by the use of integration and simplification algebráica.Años 70 - David Marr proposes new theories of Computer Vision, for example, how to distinguish a desired image in the nuances of it, color, edges, texture and forma.Años 70 - It develops the first system for Natural Language Understanding, implemented by Terry Winograd, a researcher at MIT, the SHRDLU, which is integrated a robot must obey orders humanas.1972 - the first implementation is developed language PROLOG (Programming in Logic) by Frenchman Alain Colmerauer, programming language for AI, based on predicate calculus logic (Horn clauses ) and the Resolution Principle. This language was considered by the Japanese, the language of the machines of the future.
