I have a large MILP model in Pyomo on Python and I am running into problems for a certain set of input parameters. After finding an optimal objective after the barrier solving in 65 iterations and completing the root crossover it gets stuck int the root simplex...
See the three screenshots of the log attached.
On the last screenshot it can be seen that it does twice exactly the same thing at iteration 445562 with the same result and then after this nothing happens anymore.
Thanks a lot for your help and all the best
