How to terminate once barrier solves problem

Answered

Debopam Bhattacherjee

The log shows:

"Barrier solved model in 57 iterations and 5505.27 seconds
Optimal objective 4.36903012e+00

Root crossover log..."

I want gurobi to terminate after barrier finds an optimal objective without moving over to root crossover.

Is there an easy knob to do this? Below is the current command:

"gurobi_cl Method=2 BarConvTol=1e-2 Crossover=0 ResultFile=result.sol lp_input.lp"

Thanks in anticipation!

If you have an LP, those options should do the trick, but for a MIP, Crossover is unavoidable. Note that SOS constraints and General Constraints (usually) make the model a MIP.
