BarConvTol

Barrier convergence tolerance
 Type: double
 Default value: 1e-8
 Minimum value: 0.0
 Maximum value: 1.0

The barrier solver terminates when the relative difference between the primal and dual objective values is less than the specified tolerance (with a GRB_OPTIMAL status). Tightening this tolerance often produces a more accurate solution, which can sometimes reduce the time spent in crossover. Loosening it causes the barrier algorithm to terminate with a less accurate solution, which can be useful when barrier is making very slow progress in later iterations.

Note: Barrier only
