`max_seconds` parameter not working

See original GitHub issue

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 MILP Solver 
Version: devel 
Build Date: Mar  8 2022

compiled from master as indicated above on a Mac M1.

I can provide a minimal example, however I’m pretty sure this is a simple oversight. The only difference between my code working and not working is addition of the max_seconds parameter in the optimize() call. Let me know if you need any other info.

To Reproduce

model.optimize(max_seconds=1234)

In the same code base, calling optimize() without any parameters works perfectly.

Expected behavior

Solver terminates after at most 1234 seconds.

Desktop (please complete the following information):

Operating System, version: macOS Monterey Version 12.1 (21C52)
Python version: 3.9.9
Python-MIP version (we recommend you to test with the latest version): 1.13.0

Additional context Add any other context about the problem here.

I’m not actually a maintainer here. I did assign the ticket to you, which I can do, but I would leave it to the maintainers to add you to the project. That’s not required to submit a PR, however.

@gewesp You can easily fork this project in your private space and from there you can create a pull request (PR) into the python-mip repository. You don’t need any rights to the project to create it, only as a maintainer you can merge the PR.
