| iterate | - the current iterate number (>=0) | |
| f | - the current function value | |
| gnorm | - the square of the gradient norm, duality gap, or other measure indicating distance from optimality. | |
| cnorm | - the infeasibility of the current solution with regard to the constraints. | |
| xdiff | - the step length or trust region radius of the most recent iterate. | |
| reason | - The termination reason, which can equal TAO_CONTINUE_ITERATING |
