Barrier convergence tolerance for QCP models
  Type: double
  Default value: 1e-6
  Minimum value: 0.0
  Maximum value: 1.0

When solving a QCP model, 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 may lead to a more accurate solution, but it may also lead to a failure to converge.

Note: Barrier only
