I think this week three important discuss . one is person Alen Turing.
He was one of the genius. He was a founder of computer science-Artificial intelligence.
and He was mathematician, philosopher and codebreaker.
But he arrested as a homosexual and he loss of security clearance. So he suicided.
Turing make a "imitation game". It is played with three either sex. The interrogator stays in a room apart from the other two. the object of the game for the interrogator is to determine which of the other two is the man and which is the woman. This game give us question 'Can machines think?'. That's a wonderful thinking by that time. That was influence make a AI(Artificial intelligence).


Second is GPS (General Problem Solver). Separated its knowledge of problems form its strategy of how to solve problems : not real- world problems : Soar GPS as a “solution”: The General Problem Solver by Herbert Simon, Allen Newell, and Clifford. (Sorry,I'm lose my memory. I don't remember Dr.yoon said. ㅜ.ㅜ)


third is Artificial intelligence. Artificial intelligence is the science of making machines do things that would require intelligence as if done by humans.
artificial intelligence: research areas are Knowledge Representation,ProgrammingLanguages,Natural Language (e.g., Story) Understanding ,Speech Understanding,Vision,Robotics ,Machine, Learning and Planning GPS is what is known in AI as a “planner.” (not global positioning system!!! it is a computer program for theorems proof, geometric problems and chess playing Newell, Alan, Shaw, J. C., and Simon, Herbert A. “GPS, A Program That Simulates Human Thought.” In Computers and Thought, ed. Edward A. Feigenbaum and Julian Feldman. pp. 279-293. New York, 1963 .To work, GPS required that a full and accurate model of the “state of the world” (i.e., insofar as one can even talk of a “world” of logic or cryptoarthimetic, two of the domains in which GPS solved problems) be encoded and then updated after any action was taken (e.g., after a step was added to the proof of a theorem).



Next friday mid-term exam. This lesson very difficult. So I'm not confidence. But Dr.yoon hint the exam. so I will study hard as is usual with me and I get good mark. thank you ^^
