监控文本文件内容变化的文本比较算法

Text comparison algorithm for detecting content change in text files

为了判断文本文件的内容是否发生变化,确定变化的内容,并尽量降低系统开销,提出了一种基于位置的文本文件比较算法。算法利用位置优先原则,简化了比较过程。实验结果表明该算法可以应用于文件监控,而且易于理解。

In order to know whether the content of a text file is modified and determine what is changed, while making the system spend as small as possible, an algorithm based on locality was presented. Because of the locality priority, the process was simplified. The experiment results show that this algorithm which is easy to understand can be used for file detection.
