Dear Christian,
Thank you for your reply first, and I will try to give more details.
In fact, I've worked with scip and implemented new projects . And these
worked perfectly.
Now, I've just moved to GCG to use branch and price algorithm. I've just
installed gcg with the help of the official documentation :
http://www.or.rwth-aachen.de/gcg/doc/INSTALL.html. After that i would use
gcg example according to the offcial documentation also :
http://www.or.rwth-aachen.de/gcg/doc/EXAMPLE.html.
When using this last page, and precisely after typing the command *optimize*,
I got the errors mentionned before.
I tried more examples, but had similar errors.
I've just used scip in interactive shell, on TEST0055.lp and it worked.
Thank you in advance.
Cordially,
Mohamed Mustapha KABBAJ
