Okay @blegat this is a problem. Pavito uses Cbc as a sub-solver, and the switch to MatrixOfConstraints broke it because it no longer supports incremental modifications. What Pavito really needs to do is use Cbc inside a caching optimizer, but it isn't clear how to know whether a given solver needs a cache |

This failed because of the solver name checks :( |

I've marked a number of TODOs in the test where I commented out some failing tests. They're mostly issues with Pavito cycling. Since I haven't really changed any functionality in Alpine directly, I'd suggest we merge this PR first to get a version working with the latest JuMP and then fix the remaining issues.

Tests are passing (with the exception of the excluded ones due to Pavito cycling), so I'll merge this so I can make some other fixes. |
