From the decade of 1950 to 1970, Artificial Intelligence showed a great amount of development, with computers able of performing several human like actions, such as solving word problems, proving theorems and even speaking languages. As such, in the 60s there were already numerous laboratories established all over the world dedicated to this area, but all this progress slowed down, entering a phase referred to as the AI Winter. The AI winter represents the period of time during which the research of Artificial intelligence had lost interest and the government pulled back on AI research. However, in the 80s the research of AI was brought back, with the success of “expert systems”, a computer system designed to be able to solve complex problems, modelling human expertise. These systems increased the use for industrial applications, with many companies becoming involved in developing and making use of these systems. But even with this fervor around expert systems, AI research declined after some time once again, entering another period on which the area of AI experienced a stalemate. However, AI still managed to show progress, and after some time machines begun to show even greater signs of intelligent development, AI began to challenge human skill in games such computer chess, with “Deep Blue” becoming the first ever AI to beat a chess world champion, Garry Kasparov, in 1997. AI continued growing until our days, improving its logical skills, with faster computers, improvements to algorithm and gaining access to huge amounts of data. AI is now present in many aspects of our daily life, such as our phones, computer programs and video games, internet algorithms, etc.
