Hi @DaveLanday! I'm currently working on a similar project, and I think you'd just need to have a persistent Highs Model that you keep adding rows to (from cutting planes or branching).
Although here some functions like the ones that change the bounds of variables could be helpful (for enforcing branching decisions) they don't exist yet in the safe interface. @lovasoa have you thought about allowing (unsafe) access to the underlying highs pointer through an unsafe function? that would probably help projects like this reach the full highs API and test it with their code before contributing with PRs.

I appreciate the feedback. Would use of the highs-sys crate directly suit me better? It looks like it may be a bit more low level. For example, it looks like I can build with support for reading mps.gz files etc…
