Times are wallclock time. 14 14 15 No fixing of continuous variables at the moment, as the resulting EF MIP is solvable. 16 Slamming after iteration 100, but not really  we haven't defined variable slam priorities. Cycle breaking when length exceeds 30. 15 No fixing of continuous variables (or waiting for their convergence), as the resulting EF MIP is solvable. 16 Slamming after iteration 100, but not really  we haven't defined variable slam priorities.
