A python Linear Programming API
### Discussed in https://github.com/coin-or/pulp/discussions/698 Originally posted by **TCRichards** November 3, 2023 Hello, I’m working on a real-time decision making tool that uses PuLP with the CBC solver to solve optimization...
Details for the issue -------------------- #### What did you do? Consider writing the following simple LP to an MPS file: ```python model = LpProblem("Test problem", LpMaximize) x = LpVariable("x") model...
Hi there. I am testing out different open-source LP solvers for performance on my LP problem. While I had recently been using `PULP_CBC_CMD`, which works great, I wanted to try...
Describe the new feature -------------------------- Add support for Github Actions ARM Linux testing of built CBC monolithic binary. While a test for the CBC project might also be done and...
Maybe @siwy knows about this since it was him who brought the changes with setLogCallback in https://github.com/coin-or/pulp/commit/6a8e4631fdc09575834b2017e339c74017a5ac07. The test that fails is `test_msg_arg`. It only fails in Ubuntu, not in...

The result is that the current master branch is producing the same...
**System:** MacBook (INTEL CPU), Ventura 13.2, Python 3.8 PuLP 2.7.0 When calling either HiGHS or CBC via PuLP on the MipLib2017 benchmark problems, (at least) two of them seemed to...
----------------------- I am new to pulp. when use pulp with CBC solver. it shows ``` At line 2 NAME MODEL At line 3 ROWS At line 29 COLUMNS At line...
I have a linear problem, and I found that the problem is infeasible. And the model status is : Linear relaxation infeasible but it can return a solution and I...
Details for the issue -------------------- #### What did you do? I am currently encountering a very weird issue with the `PULP_CBC_CMD` solver via `pulp` package in Python (CBC MILP Solver...
