**Describe the bug** When changing the preprocess-parameter of the model preprocess is still performed as default. **To Reproduce** Set preprocess parameter to 0, still observe preprocess to be performed in...
After seeing "Reduced cost fixing - 45 rows, 117 columns - restarting search" message, variable access in lazy_constrs_generator callback will fail. All variable names are changed. I see that both...
Consider the following code to model the maximum independent set problem to solve the maximum clique using MIP and NetworkX: ``` import mip import networkx n = 2 ** 3...
Hi, @h-g-s , @tuliotoffolo , I'd like to report a vulnerability issue in **mip_1.13.0**. ### Dependency Graph between Python and Shared Libraries  ### Issue Description As shown in the...
When running a model with lazy constraints generator enabled I observe that strong branching finds an integer solution but finally there is no solution found. Below you can find log...
**Describe the bug** `max_seconds` doesn't work for me currently, it leads to: ``` Starting MIP optimization Unrecognized parameter - maxSavedSolutions=10, exiting... ``` This is with: ``` Welcome to the CBC...
when mip is installed it comes with binaries for windows, mac, and linux. These are very large - in my experience making mip larger than even numpy or pandas! It...
Hi there, I have been using mip for a long time on python, but these days I switched to pypy and noticed the following problem: NameError: name 'cbclib' is not...
**Describe the bug** I am writing a program that solve MIP and it works well when I directly run the code. But after I use pyinstaller to pack my code...
