美国行记5

Today，we continued our second study of UCB. We studied. another course about AI，but from a different perspective. We studied it from computer programming and biological and mathematical way. We study it from，what is AI， it，s history，how to plan agent，different searching  method ：the BFS，DFS，greedy and A star.  We then watch different programming videos about how to design games using AI technology. We also learned a lot of theories about AI ：minimax values，evaluation functions and how to learn from error. Overall，it was a great lesson. At noon，we ate in a Sichuan restaurant，the food tastes delicious. I haven，t eat Sichuan meal for a long time. In the afternoon，we saw the campus of Berkeley by climbing the mountains. The mountain was so big. Then we found a place where we played frisbee in a group. It was great. We had a really powerful and relaxing day.
