数据挖掘里面 需要频繁项集的算法 因为当初还没有学习数据库 所以算法只能算是模拟的-It needs data mining algorithm for frequent itemsets because the study database was therefore not only a simulation algorithm

数据挖掘（概念与技术）书上的apiori算法实现。apiori剪枝算法使用候选项集产生发现频繁项集。-Data Mining (conceptual and technical) in a book apiori algorithm. apiori pruning algorithm uses candidate item set generated frequent itemsets found.
