这一次写的内容是黄金豆小游戏，由于现在偏重写服务器端。对于算法层面其实涉及不多，更多偏于工程上的架构。

总而言之本次作业的服务器核心是用web.py所写，而且为了方便其他用户写客户端，架构非常简单。

具体而言，首先从接口上来说，服务器只涉及到两个表单操作，注册表单和提交表单，注册也同样可以在网页上进行。

由于是测试服务器通讯的，为了方便客户端调试很多细节与题设有所不同，但修改起来非常简单。

注册模块：

　　　注册需要提交用户名和密码{[username],[password]}

　　　1.只有在游戏开始前可以进行注册。

　　　2.注册失败，会返回-1.

　　   3.注册成功，会返回0.

　　   4.注册信息会录入注册表中。

提交模块：

　　   提交模式需要提交用户名和密码以及给的数字{[username],[password],[nut]}

　　   1.如果下一轮还未开始用户已经提交，便会等待。

　　   2.如果用户提交后，本轮还未结束，依然等待直到，结束，返回G值

　　   3.若登录失败，则返回-1（测试完毕后，若为按时提交也返回-1）

游戏模块：

　　   1.会等待本轮用户提交完毕才会给出G值（测试完毕后改为，若1秒之后仍未提交，直接失败）。

　　   2.分数策略如提所述。

即服务器与客户端同步，以免发生一开始客户端设计的缺陷引发客户端一次都无法返回有意义的结果。

正式发布时，服务器将不等待客户端的同步。

画图由一个monitor实时返回此时AVG的值。值得一提的是，由于web.py对于线程数有限制（10），我们修改了web.py source里的代码，把THREAD数目放宽才使得该项目成为可能。

测试程序：

开了30个线程测了50组数据，图像反应正常。
