代码注重B树插入、删除的算法逻辑，适用于 学习者研究B树实现的核心思想。代码中无庞杂的无关操作(focus on B-tree code insertion, deletion algorithm logic applies to B-tree research learners to achieve the core idea. The code has nothing to do with the complex operation )

说明：  C++实现摄影测量后方交会程序（Photogrammetry）(photogrammetry resection)

一个类似遥控器的源码程序。可以有多种功能，可以听，打开等。 你如果能连接到具体的硬件上，小小修改。就可以直接用了。(A similar remote control of the source program. Can have multiple functions, you can listen to, open and so on. If you can connect to specific hardware, a small modification. Can be directly used.)

用通用图搜索算法实现农夫过河问题，建立了通用图搜索算法的模板，可以稍作改动解决其他如汉诺塔问题、水壶倒水问题等(The general graph search algorithm is used to realize the problem of farmer crossing the river, and the template of the general graph search algorithm is established, which can solve other problems such as the Hannover Tower problem and the water pouring problem of the kettle with slight modification.)
