@LucaCappelletti94 you can have a look at https://github.com/SCIP-Interfaces/PySCIPOpt/blob/master/tests/test_pricer.py
you can implement your pricer within SCIP, so you don't need to have a new model.
If you are interested, you can learn more about pricers in http://scip.zib.de/doc-5.0.1/html/PRICER.php
Matthias is referring to the examples that we have in PySCIPOpt. We've been lazy because we do not really have example written the scip-way. However, the tests, they are the scip-way
pyscioptway. I suppose it would take at most one hour.
