About cut selection support. #319

Open only-changer opened 2 years ago

Hi, thanks for such a great repo. I have read your paper from nips20, where you mentioned that "We are actively working on node selection and cut selection." I wonder if the Ecole supports cut selection now?

Hi @only-changer ,

We have students working on those topics here, but nothing ripe enough to be integrated into Ecole.

Regarding cut selection, please note that SCIP 8 offers a new API for cut selection, which should make the development of a cut selection environment in Ecole much easier. https://www.scipopt.org/doc/html/group__PublicCutSelectorMethods.php

If you would like to contribute, that could be a nice way to go :)

Best, Maxime
