图书馆管理系统是图书馆管理工作中不可缺少的部分，它对于图书馆的管理者和使用者都非常重要，所以图书馆管理系统应该为管理者与读者提供充足的信息和快捷的数据处理手段，但长期以来，人们使用传统的人工方式或性能较低的图书馆管理系统管理图书馆的日常事务，操作流程比较繁琐。一个成功的图书馆管理系统应提供快速的图书信息检索功能、快捷的图书借阅、归还流程。从读者与图书馆管理员的角度出发，本着以读者借书、还书快捷、方便的原则，本系统具有以下特点：  确保系统具有良好的系统性能，友好的用户界面。  较高的处理效率，便于使用和维护。  采用成熟技术开发，使系统具有较高的技术水平和较长的生命周期。  系统尽可能简化图书馆管理员的重复工作，提高工作效率。  简化数据查询、统计难度。 -Library management system is the work of library management indispensable part of its managers and users of the library are very important, so the library management system for managers and readers should provide sufficient information and efficient means of data processing, but a long time , the use of traditional artificial or lower performance of the library management system of the day-to-day management of library services, operating relatively cumbersome process. A successful library management system should provide rapid information retrieval library features, and quick to borrow books, the return pro

实现求解平面最近点对的复杂度为nlgn的算法。程序要求能够自动生成至少100万个点，并利用该算法求解。此外，要求支持图形界面的算法输入与输出。在此基础上，添加n^2级算法的实现，并比较相同规模下，两种算法的时间消耗。-Solving the nearest point on the plane to achieve the complexity of the algorithm for nlgn. Program requires the ability to automatically generate at least 1 million points, and the use of the algorithm. In addition, the algorithms required to support graphical user interface input and output. On this basis, add the n ^ 2 Ji Implementation of the algorithm and compare the same scale, the two kinds of algorithm" s time consuming.
