nlp_scaling_max_gradient:

Maximum gradient after NLP scaling. $ \;$
This is the gradient scaling cut-off. If the maximum gradient is above this value, then gradient based scaling will be performed. Scaling parameters are calculated to scale the maximum gradient back to this value. (This is g_max in Section 3.8 of the implementation paper.) Note: This option is only used if "nlp_scaling_method" is chosen as "gradient-based". The valid range for this real option is $ 0 < {\tt nlp\_scaling\_max\_gradient } < {\tt +inf}$ and its default value is $ 100$ .
