View a description the nloptr status codes
Prints a description of the status codes from the nloptr optimization routine.
statusCodes()
| Code | Description |
| 1 | Generic success return value. |
| 2 | Optimization stopped because stopval was reached. |
| 3 | Optimization stopped because ftol_rel or ftol_abs was reached. |
| 4 | Optimization stopped because xtol_rel or xtol_abs was reached. |
| 5 | Optimization stopped because maxeval was reached. |
| 6 | Optimization stopped because maxtime was reached. |
| -1 | Generic failure code. |
| -2 | Invalid arguments (e.g. lower bounds are bigger than upper bounds, |
| an unknown algorithm was specified, etc.). | |
| -3 | Ran out of memory. |
| -4 | Halted because roundoff errors limited progress (in this case, the optimization still typically returns a useful result.). |
| -5 | Halted because of a forced termination: the user called nlopt_force_stop(opt) on the optimization's nlopt_opt object opt the user's objective function or constraints. |
No return value; prints a summary of the nloptr status codes to
the console.
