A brute force approach for mining association rules ispute the sup port and confidence for every possible rule. This approach is prohibitively expensive because there are exponentially many rules that can be extracted from a data set. More specifically, the total number of possible rules extracted from a data set that contains d items is R =3d 2d+1 +1. 6.3 The proof for this
