Just for background, the original specification for the MPS format goes back decades, literally to the time when punch cards were used for input, and only allowed for minimization (which...
This is almost certainly because of coin-or/CoinUtils#211. CoinUtils needs to be installed before you build Cbc. This will likely go much smoother if you use coinbrew.
I have had some bug reports from people trying to use Clp/Cbc on M1, but they were related to bugs in the build system. My impression is that there are...
Thanks all for poking at this. I don't have much bandwidth for it at the moment, maybe next week.
Since this bug was reported fixed for version 1.2 on 6/5/2009, I went back and checked the commit log around that time. It appears that there was a series of...
Great, if you are willing to do a PR, that would be helpful.
[CyLP](https://github.com/coin-or/CyLP) will read in MPS files and solve them in Cbc (but not LP, unfortunately). See [here](https://coin-or.github.io/CyLP/modules/CyCoinMpsIO.html).
Looks like this was resolved in duplicate issue https://github.com/coin-or/python-mip/issues/276. Also related to https://github.com/coin-or/coinbrew/issues/73.
The Cbc project is completely separate from `python-mip` and only provides binaries for a limited set of platforms (the ones we do build and test for using Github Actions). Providing...
@SBuercklin, thanks for the thorough bug report. I guess this is more of a feature than a bug. I believe that Cbc doesn't ever interrupt the LP solver (Clp), which...
