Why did we use temp? How do isExists and isContained help us? What's going on exactly in these two parts of code? But I can't see how this is implemented in the previous code. Now I know of the Apriori Gen process where we make itemsets into larger item sets by joining them together. If (!Lk.ToString().Contains(subTemp ) ) isContained = false and the focus is not with the candidates seeking the same items set temp

If temp contains the entry for L in the (itemset size +1) If (subL1mInsubL2 = false) temp = temp + "," + subL1 If (subL1 = subL2 ) subL1mInsubL2 = true Compare two items in L, and set them in temp Static ArrayList AprioriGen (ArrayList L)ĪrrayList Lk = new ArrayList () //List to store generated Candidate Itemsets I found an implementation for the Apriori algorithm on the Internet but there is something I can't understand in it.
