Algorithm 1

The Apriori algorithm.

(1)	Ck: Candidate itemset of size k
(2)	Lk: frequent itemset of size k
(3)	Ll = {frequent items};
(4)	for do begin
(5)	Ck+l = Candidate generated form Lk;
(6)	for each transaction t in database do
(7)	increment the count of all candidates in
(8)	Ck+l that are contained in t
(9)	Lk+l = candidates in Ck+l with min_support
(10)	end
(11)	return ;
