Hi @AP,
as far as I know, this parameter is not part of the GSP algorithm. You can work with other variations like CloSpan, PrefixSpan for that.

Hi @AP,

I worked with this parameter in other algorithms but not directly in GSP, but I think that the windows size parameter of GSP is equivalent in this case.

you mean the windows size parameter of GSP is equivalent to maxspan ？

Hi @AP,
I implemented the maxspan in python using the Clospan algorithm, not the GSP, but as mentioned this blog
http://simpledatamining.blogspot.com/2015/03/generalized-sequential-pattern-gsp.html

" Window sizes limit the span of time when transactions are deemed to support a sequence. (e.g. I only want buying patterns for pregnant women during a 9 month window)"

there is no maxspan parameter for operator Generalized Sequential Patterns？why？
