Indeed, I think it's significantly faster run from the command line in debug.

What happens if you use the MATLAB integer programming solver - which (since 2024a) is HiGHS?

I've looked at this with detailed logging on, and see what's happening. Implementing a fix isn't difficult, but it's slightly scary, as it will change the behaviour of the simplex...

I don't think this is the same as the original case in this issue. I don't quite understand why simplex is stopping with 23 small primal infeasibilities, although you have...

Odd problem. Origin is primal feasible with one dual infeasibility of 0.000263582, so its square is less than the dual feasibility tolerance of 1e-7. Hence `HEkkDual::solve` forces phase2 with the...

Actually needs > enum class Status { kNotSet, kOptimal, kInfeasible, kUnscaledDualFeasible, kUnscaledPrimalFeasible, kUnscaledInfeasible, kUnbounded, **kTimeLimit, kInterrupt, kMemoryLimit,** kError }; feeding into > enum class HighsMipInstruction { kContinue, kTimeLimit, kInterrupt, kMemoryLimit...

There are a couple of presolve rules that lack timeout checks. Similarly in the MIP solver. In the case of the presolve, I have the example in #2217, and for...

Does this happen with v1.9.0, and/or if you set threads=1?

We will be writing our own version of PDLP, and will look to enable it to run on Macs

Work has started on the new PDLP solver but it's not yet part of the repo. We've got external funding to develop it that will grease the wheels and will...
