hello all,
I have a column generation problem,
in the slave model i find all the duties for each trip...

somtimes my cp model slave cant find any column for a specific trip so the master model cant find solution for my problem.
how i can know which constraint i have to modify or to ignore in the slave model (cp model) in order to get at least one column for  a specific trip

Thank you
