at 1:47, since site1 was approved for his request, shouldn't the token be passed from site2 to site1??? and then when site3 requests next, the process goes on...?
{(ab)} is frequent and {b,f} is frequent and the have common item b. So we can join those two sequences to form 3-length sequence. While forming 3-length sequence in first sequence a,b are in same transaction and in second sequence b,f are in different transactions. Therefore we form 3-length sequence {(a,b),f}.
Thanks for your explanation. At the last step, is the support of {abfe} = 2? It seems that support of {abfe} = 1. Would you mind to answer this please?
What if the item in superset has greater support count than it predecessor? Suppose, in the given example support(B) = 4 and what if support(BE) = 5; in that case would B be considered as Closed? TO summarize, do we check equality or greater than/less than for clossness?
