Other than the use of `np.save` and `np.load`, what you're doing here is exactly what I'm doing when saving the `col_value` in code. Hence I'm tempted to assume that there's...

> Just passing along some real-world usage experiences to the HiGHS developers; I'd appreciate any feedback or opinions. I assume that you're looking at HiGHS as an alternative to OML...

The problem with 'EFD_2029.mps' is that the file is incomplete. It ends in the COLUMNS section with > O0462233 SRmiss3C 0.35432097 and an MPS file must end with a >...

We'll try to reproduce this There are a couple of reasons why presolve can take an excessive amount of time. One solution would be to have a separate time limit...

Hmm... Can you easily switch off the flow cover constraints by default? That way the code is merged, possibly avoiding conflicts that might occur if merged later. Probably a useless...

Thanks, we will add this to the C# API

Sure, although the situation isn't quite what Gurobi needs to resolve. If HiGHS presolve identifies that the LP is dual infeasible then the LP is (primal) infeasible or unbounded and,...

So long as folk realise that if the ray's not already available then to find it could be a significant cost, then it's easy to add the code to calculate...

I'd rather leverage the current functionality, where users can query whether a ray is already available by passing `nullptr` for the ray data. If the user passes valid pointers, then...
