I'll try to get it working myself and update the HiGHS API to handle MIPs and QPs in the process

Thanks to @berkorbay, I've installed PuLP and used it to call HiGHS for https://coin-or.github.io/pulp/CaseStudies/a_blending_problem.html and https://coin-or.github.io/pulp/CaseStudies/a_sudoku_problem.html I've made some modifications in my `highs_api.py` [highs_api.py.txt](https://github.com/coin-or/pulp/files/9000392/highs_api.py.txt) and documented these, together with some...

So, am I right in thinking that the Highs MIP solver can now be called from PuLP?

Will it help that HiGHS is now available as `pip install highspy` (on Linux and MacOS, with Windows WIP)? Accompanying this will be a `pybind11` thin wrapper around each of...

Sorry about this. The LP file reader hasn't been tested on files of this size - not that it's particularly large. Thanks for your detailed observations: I'm sure that they...

Thanks. @feldmeier found the reported behaviour to be odd, but if you've seen it in GAMS, then anything you can do to address it would be much appreciated.

Is this improved if you use `master` now that @svigerske has improved the performance of the .lp reader?
