Out of winter
During this period, researchers began to explore artificial intelligence problems from multiple angles and no longer relied too much on a single method. Some emerging research fields, such as machine learning, natural language processing, computer vision, and reinforcement learning, gradually emerged.

However, as their research progressed, they found that achieving artificial intelligence was much more difficult than expected. Early AI systems performed well when dealing with simple problems, but their panama mobile database performance dropped significantly when faced with complex, ambiguous problems or those that required background knowledge. These limitations prompted researchers to seek more efficient and powerful methods to improve the performance of AI systems.
Take the Logic Theorist, a machine developed by Simon and Newell, for example. It is an artificial intelligence program based on logical reasoning that can prove mathematical theorems. Although it has been successful in solving some simple mathematical problems, it still faces challenges in computing resources and knowledge expression when dealing with more complex problems.
