国庆看着女篮比赛，中国 vs 美国，落后 20 多分，还不放弃的追赶，实在太难了。
还好用 OptaPlanner 做 APS 排程，也没有那么难嘛！
1、代码工程
这个是在官方 sample 基础上，做了简化优化的版本，方便各位初学者调试。
git clone https://gitee.com/optaplanner/optaplanner-study.git
复制代码
用 IDEA 工具，打开 optaplanner-study\OptaPlannerHelloworld，如下图，更新 maven 配置后，运行主程序 TimeTableApp，即可。
2、运行效果
控制台输出以下信息，说明运行正常。输出的是 教师、教室、课程的排程表。

3、进阶
当你已经可以运行第一个 OptaPlanner 的程序，我们来点高阶的：
布置一个小作业，如果教室从 3 个，变成 4 个；
年级从 9、10 两个年级，变成 9、10、11 三个年级。
如何修改程序，获得最优的课程表？ 做
完的朋友，欢迎把结果发给我；遇到困难的同学，也欢迎留言说明遇到的问题。
