MAX_STEEP_STEPS |
|
| MAX_STEEP_STEPS {integer}
|
| Maximum number of steepest descent steps before starting the conjugate gradients optimization.
|
| This optional keyword expects an integer. Default value: 0
|
RESTART_LIMIT |
|
| RESTART_LIMIT {real}
|
| Cosine of the angle between two consecutive searching directions. If the angle during a CG optimization is less than the one corresponding to to the RESTART_LIMIT the CG is reset and one step of steepest descent is performed.
|
| This optional keyword expects a real. Default value: 9.0000000000000002E-01
|
FLETCHER_REEVES |
|
| FLETCHER-REEVES
|
| Uses FLETCHER-REEVES instead of POLAK-RIBIERE when using Conjugate Gradients
|
| This optional keyword expects a logical |
| This keyword behaves as a switch T
. Default value: F
