| TYPE GOLD
|
| 1D line search algorithm to be used with the CG optimizer, in increasing order of robustness and cost.
|
| This optional keyword expects a keyword. Default value: GOLD
|
| valid keywords: NONE : take fixed lenght steps
2PNT : extrapolate based on 2 points
3PNT : extrapolate based on on 3 points
GOLD : perform 1D golden section search of the minimum (very expensive)
FIT : perform 1D fit of a parabola on several evaluation of energy (very expensive and more robust vs numerical noise)
