What does it mean to not have RealConstraint? As far as I tested the model used all integer variables and integer coefficients and still got the error. Is there a...

Thanks for the issue report. Do you have an example in the form of reproducible python code or json file of the problem lp you're trying to solve? On Thu,...

Hello and thanks for the detailed report and MWE. Unfortunately, I think it may be hard to make it work like you expect. In PuLP, we only store the variables...

I was unsure on whether it should be pulp, the solver or the user who should identify (and potentially extract) empty columns in the matrix. Many modelers do offer warnings...

can you update with master again? the tests were failing for another reason. thanks.

do you feel like doing a PR with the change? check this part https://github.com/coin-or/pulp/blob/de4dbb7cc3a9ed2bd0e88fe9e45f7a66571bad1f/pulp/apis/cplex_api.py#L432-L463 to see how we feed the cplex library with the current configuration.

Thanks! There's two things: 1. Users should be able to create variables with duplicated names (at least that's was the design decision). 2. 100% agree they should be better notified....

I've seen this issue when using CPLEX. For some reason, and with some versions of CPLEX, if the solver does not find an integer solution in the timeLimit, the solver...

Yes, we use the command line interface of HiGHS in HiGHS_CMD. We should probably update the pip version soon. But as the comment in the other issues says, you can...

could you please provide an example? better yet a completely reproducible one?
