Dear Alreva,

your mail had to be forwarded manually because you are not subscribed to
the GLPK help list, cf.
https://lists.gnu.org/mailman/listinfo/help-glpk

The source distribution of GLPK is available at
ftp://ftp.gnu.org/gnu/glpk/glpk-4.47.tar.gz

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

Xypron
