The algorithm needn't generate candidate itemsets and scan database, because it employs FP-Tree to store trasanctions in database compressedly and takes full advantage of the characteristic of FP-Tree.Consequently,the complexity of space and time the algorithm used is reduced obviously in the procedure of data mining.In a thorough experimental analysis of our algorithm on real and synthetic data,we isolate the effect of the individual components of the algorithm. Our performance numbers show that MFP-Miner outperforms previous work.

该算法利用频繁模式树来压缩存储数据库中的事务，并充分利用频繁模式树的特点，在挖掘最大频繁项目集的过程中不需要产生候选项目集和扫描数据库，从而减少了算法在挖掘过程中使用的存储空间和计算时间，通过实验结果显示，该算法的性能优于同类算法。

When should searching engine spider to get when requesting a certain URL 404 condition are responded to, know this URL namely already invalidation, index no longer this webpage, feedback to delete this URL denotive webpage from inside index database to data center, of course, delete a process to need for a long time likely, and when should searching engine to get 200 condition are responded to, can think this Url is effective, can index, can collect its index database, such result is these two different Url have identical content: Define the content of 404 wrong pages oneself, this meeting is brought about appear duplicate webpage problem.

当搜索引擎蜘蛛在请求某个URL时得到404状态回应时，即知道该URL已经失效，便不再索引该网页，并向数据中心反馈将该URL表示的网页从索引数据库中删除，当然，删除过程有可能需要很长时间，而当搜索引擎得到200状态回应时，则会认为该url是有效的，便会去索引，并会将其收录到索引数据库，这样的结果便是这两个不同的url具有完全相同的内容：自定义404错误页面的内容，这会导致出现复制网页问题。
