It doesn't check _everywhere_ in presolve. If you can let me have your model then I'll investigate. Thanks
I've reproduced this behaviour. Presolve is normally a relatively small proportion of solution time so, a time limit that's meaningful for solution time is very rarely reached in presolve. There...
Thanks: with that number of binary variables, it's probably a good job that presolve works well! I'll still put in the time-out, as it's easily done
This is rather better now. MIP presolve spends a lot of time `probing` to fix binary variables, and during this call there's no test for time-out (although I could add...
The time limit is imposed for some presolve operations, but others can go into a "black hole" where the current run time isn't tested
Your experts wouldn't know what's happening in presolve. If you can give me a small instance of your model using https://linopy.readthedocs.io/en/latest/generated/linopy.model.Model.to_file.html I can try to reproduce the issue (with an...

I was just thinking that someone will want to plot it sometimes, although that is done by parsing HiGHS.log with the Python utility
