Dear Xypron,
Thank you very much, I just subscribed to the list. So about my question, you think then this is theoretically possible to solve my problem by callback functions?

Dear Alreva,

your mail had to be forwarded manually because you are not subscribed to
the GLPK help list, cf.

The source distribution of GLPK is available at

In glpk-4.47/doc/glpk.pdf read the following chapters:
5.4 The cut pool routines
5.1.1 Using the callback routine

Best regards
