parallel CBC

[mhechthz]

Since making python-mip fit for Python >=3.13 is on track I wonder, if CBC could be added with parallel mode?

As far as I know or understood, CBC can run in parallel if properly compiled. Since no CPU comes without cores these days I think this could be default or configurable from python-mip.

EDIT: CPLEX and SCIP can do this and get a big advantage over CBC only by parallelization which is a pity.

Probably your issue is already addressed with the new releases of python-mip because now CBC is provided via the Python distribution of CBC called cbcbox, which optionally also supports parallel branch-and-cut, see cbcbox's list of highlights.
