八数码问题也称为九宫问题。在3×3的棋盘，摆有八个棋子，每个棋子上标有1至8的某一数字，不同棋子上标的数字不相同。棋盘上还有一个空格，与空格相邻的棋子可以移到空格中。要求解决的问题是：给出一个初始状态和一个目标状态，找出一种从初始转变成目标状态的移动棋子步数最少的移动步骤。 -8 issue of the digital problem, also known as Nine-palace. In the 3 × 3 chessboard placed eight pieces, each piece is marked 1 to 8, a number of different pieces on the subject are not the same. There is also a board space, and spaces adjacent pieces can be moved to the space. To be resolved is: given an initial state and a target state, to find a target state from the initial movement into the least number of pieces of mobile steps step.

This functions displays GUI for selecting square or rectangular part of the input image IMG. To perform selection user must click mouse twice: at two corners of the selection area. User can change the shape at any moment, even when first point is set, unless it is not forbidden by additional parameters.

用DELPHI XE10+IW 14.1编写的网页程序的服务器界面不太友好，我就编写了这个网页程序的自定义服务器界面，可以显示当前连接数，还可以自动检测移动端并显示适合移动端的网页。 有需要的朋友可以借此来开发更适合自己的网站。

Voronoi图 - 计算Voronoi图和Delaunay三角概要Voronoi图[-s-t]输出文件沃罗诺伊读取标准输入为一组点中的平面，要么写入Voronoi图和Delaunay三角到标准输出。每个输入行应该包含两个实数，用空格隔开。如果-t选项存在，Delaunay三角就产生了。每个输出线是三I J K这是在一个德洛奈三角形的三个点的索引。点编号从0开始。如果该选项不存在，Voronoi图产生。有四个输出的记录类型。是个B表示在输入点坐标LABC表明受= C与方程AX+线。 V A B表示一个顶点处A B。 Ë升V1 V2表示的Voronoi段这是行数l的子段;有编号的端点v1和v2。如果V1或V2是-1，则线延伸到无穷大。作者史蒂夫J.财富（1987）一Sweepline算法Voronoi图，Algorithmica2，153-174。
