In this paper, the author mainly explores, analyzes and evaluates the algorithms FUP and FUP for association rules updating.

本文主要对典型的关联规则更新算法FUP及FUP进行分析、探讨和评价。

An improved incremental updating algorithm SFUP is developed based on study of the principle and efficiency of FUP algorithm.

通过对挖掘关联规则增量更新中FUP算法的关键思想以及性能进行了研究，提出了改进的FUP算法SFUP。

FUP officials criticized the use of back-ups, composed of managers and supervisors, declaring that the crews did not have enough personnel and that they were poorly trained.

而FUP工作人员则指责管理方招用这些由管理人员和监工组成的后援军，宣称这些员工人力不足并且未经过适当培训。

First, the article discusses the basic ideas of current FUP algorithm, then improves it on this basis, proposes an enhanced FUP algorithm EFUP, and presents the concrete process.

首先，该文讨论了现有的FUP算法的基本思想，然后在此基础上对其进行改进，提出了改进的FUP算法EFUP，给出了具体实现方法。
