这篇文章并不试图对这个话题作权威的陈述。取而代之的是，它只是描述算法的原理，使你可以在进一步的阅读中理解其他相关的资料。

　　最后，这篇文章没有程序细节。你尽可以用任意的计算机程序语言实现它。如你所愿，我在文章的末尾包含了一个指向例子程序的链接。 压缩包包括C++和Blitz Basic两个语言的版本，如果你只是想看看它的运行效果，里面还包含了可执行文件。

-This article does not attempt to be authoritative on the subject of the statement. Instead, it merely describes the algorithm theory, so you can further understand the reading of other relevant information. Finally, this article does not procedural details. You could do any computer programming language to implement it. If you like, I end of the article contains a link pointing to an example program. Compressed package includes C++ and Blitz Basic two languages, if you just want to see it run effects, which also contains the executable file.
