Dr. Fournier-Viger

Many thanks for your work on SPM. Your paper bring me into this domain.

But when I read your paper, I found some conflict between the theory and the example. In the paper:
Closed sequential patterns [56, 48, 30, 108, 109] are the set of sequential patterns that are not included in other sequential patterns having the same support, that is: CS = {sa|sa ∈ FS∧ ̸ ∃sb ∈ FS such that sa

Good evening,

I have fixed the PDF of the paper that is hosted on my website to remove this error.

If you spot some other problems, please let me know.

Best regards,
