Association Rule Mining Is One of the Most Important Data Mining Problems. the Purpose of Association Rule Mining Is the Discovery of Association Relationship Among a Set of Items. the Mining of Association Rule Include Two Sub Problems (1) Finding All Frequent Item-Sets That Appear More Often Than a Minimum Support Threshold and (2) Generate Association Rules Using These Frequent Item-Sets. the First Subproblem Plays an Important Role In Association Rules Mining. This Paper Provides an Overview on the Design of Frequent Pattern Mining Algorithms
