Input:

I//item-sets

D//affair dataset

S//support

Output:

L//item-sets

Process of the Apriori algorithm:

K = 0://K means the times of scanning

L = Φ:

Ci = I://the initial candidate set is set to a single item

Repeat

K = K + 1:

Lk = Φ:

For each IiCk do

Ci = 0://the initial data of each item set is set to 0

For each tjD do

For each IiCk do

If Iitj then

Ci = Ci + 1:

For each Ii Ck do

If Ci ≥ (S × D) then

Lk = LkIi:

L = LLK:

CK + 1 = Apriori-Gen (LK)

Until Ck + 1 = Φ
