GMCM(4)

This is the final day. I went to sleep at 4:00 and get up at 7:00. The third problem was more difficult than the above two. We must finish a emluator as the solution of the fourth problem. But as the circumgyratetion of the tapers were not clearly we could not realize it.

The left five problems were be solved by Qiyue Yu and Yu Liu.

There were nine hours after my getting up to hand in our paper. It was so quickly that we could feel it. When we finished our work we had not yet any food.

So tired! We all need a good rest.
