遗传算法 本部分主要为了了解遗传算法的应用，选择一个复杂的二维函数来进行遗传算法优化。函数显示为y=10*sin(5*x)+7*abs(x-5)+10， 另附上雷达手册(genetic algorithm This part is mainly to understand the application of genetic algorithm, select a complex two-dimensional function to optimize genetic algorithm. The function is shown as y=10*sin (5*x) +7*abs (X-5) +10,)

这是一个小闹钟程序，可以进行一些简单的时间提醒，很小巧-This is a small alarm clock procedures can be carried out some time to remind the simple, very compact

　　由于音像制品的品种繁多,所以音像租赁对于数据的查找,修改,删除和添加等功能的需求量很大,用人工手记的方式显然很烦琐,所以本项目就是为此设计.本项目可以对音像制品进行规范化管理,进而提高经营效率,实现中小音像租赁店日常工作的管理.-as audio and video products, the wide variety and audio data for the lease to search, modify, delete and add features such as the high demand for use of artificial Notes obviously very cumbersome, so this is the project design. This item can be audio-video products for regulation and then mention the high operating efficiency, small and medium-sized audio-video rental shops daily work management.
