What's the meaning of Parameter “max gap” of Operator Generalized Sequential Patterns？

Hi @AP, 

Nice to see you again.
GSP is an algorithm for search sequences and the max/min gap parameter is useful to determine the maximun or minimun time gap between adjacent elements, to be part of same sequence.

here you have a nice explanation of this algorithm

best.
