I am not quite sure how such an integration could look like TBH.
Can you create minimal, reproducible example showing the problem here? Ideally using the {reprex} package.
Yeah, seems like a good idea. Not sure if ROI supports it though.
[HiGHS](https://github.com/dirkschumacher/ompr.highs) also supports semi continuous/integer variable. We should really do that.
It has always been possible to use other solvers apart from ROI. You just need to write your own glue code connecting the `ompr` model to an `ompr` solution. If...
You cannot at the moment.
Yes, that would be nice, but it is currently not implemented. I am not even sure the specific solver packages in R implement this feature.
Heyho @CleKraus , please also use the current github version of `ompr.roi`. I implemented this uneccessary check in the CRAN version 🙃. Will be fixed in the next version.
Can you please send me an email - the semantics of the milp backend are slightly different. This is unrelated to this issue. @CleKraus PS: really excited that you try...
