I created a MIP model with GAMS and with Python-MIP. Gams finds the optimal solution.

Python-Mip start computing, but interrupts the output before the given time limit.

Operation System Windows 11 i9 processor:

I startet with: py sclsp.py > sclsp.out

The same model runs perfectly with other data (smaller problem size)

The attached file contains the complete python-mip model sclsp.py.txt sclsp.out.txt

@Krasscheck Which python version and mip version are you using?

Krasscheck commented 2 years ago

This issue (from mip version 1.12) has disappeared in mip version 1.14.
