A*算法解决八数码
题目
The
15-puzzle has been around for over 100 years; even if you don"t know it by that
name, you"ve seen it. It is constructed with 15 sliding tiles, each with a
number from 1 to 15 on it, and all packed into a 4 by 4 frame with one tile
missing. Let"s call the missing tile "x"; the object of the puzzle is to
arrange the tiles so that they are ordered as:
1
2 3 4
5
6 7 8
9 10 11 12
13 14 15 x
where the only legal operation is to exchange "x" with one of the tiles with
which it shares an edge. As an example, the following sequence of moves solves
a slightly scrambled puzzle:

文件修改监控
ReadDirectoryChangesW 有同步和异步2种方式,
根据前面打开的文件夹对象句柄决定。
1. 异步方式,如果 CreateFile 指定了打开类型 FILE_FLAG_OVERLAPPED 就是异步方式,ReadDirectoryChangesW 调用的时候就需要指定 OVERLAPPED 参数.
接下来对文件夹I/O变化的响应判断有多种方式。
A通过不断的调用HasOverlappedIoCompleted函数(非阻塞,参数就是前面的OVERLAPPED 对象指针)的返回值来判断是否发生了 关注文件句柄的I/O操作。如果发生变化,再执行你的 switch(Buffer[0].Action) 操作过程。
B GetOverlappedResult 读取 OVERLAPPED 对象的结果。(阻塞)
C 完成端口 GetQueuedCompletionStatus (阻塞)。
其中阻塞方式,必须采用多线程的方式,否则你的主线程被阻塞的话,对话框就动不了了。非阻塞方式也可用多线程,结合hEvent对象来使用。
2.同步方式,如果CreateFile不指定FILE_FLAG_OVERLAPPED ,就是同步方式。
同步方式操作比较简单。lz的程序看来就是使用的同步方式。
在同步下,ReadDirectoryChangesW 将被阻塞,直到一个文件夹句柄的I/O操作到来,然后才能判断。所以lz的程序会死掉。
同步方式必须采用多线程,再创建一个线程,线程函数采用如下方式:
UINT ThreadProc(PVOID)
{
CreateFile();
while(1) // 如果只想监视一次文件的I/O变化,可不用while循环。
