摘要 对Pincer Search进行了改进,提出了一种新的发现最大频繁项目集的WDMFS算法。由于WDMFS算法采用了位阵存储技术和自底向上、自顶向下双向搜索策略,从而进一步提高了算法的效率,显著降低了系统的I/O成本和CPU时间。 In this paper,Pincer-Search algorithm is improved,and proposesa new algorithm for mining maximum frequent item sets based on set-enumeration tree.The proposed algorithm makes enough use of bit matrix-stored technology,and combines the bottom-up and top-down.Efficiency of algorithm is more high,cost of I/O and CPU time is reduced remarkably.
