How to scale each nonlinear constraint
Alias: nonlinear_equality_scale_types
Argument(s): STRINGLIST
Default: no scaling
Each string in scale_types
indicates the scaling type for each nonlinear inequality (equality) constraint. They only have effect when the associated method specifies scaling
.
The options are:
'value'
 characteristic value by which nonlinear constraint values will be divided. If this is chosen, then scales
must also be specified; 'value' is assumed if scales are given without scale_types
'auto'
 automatic scaling based on bounds (inequalities) or targets (equalities)'log'
 logarithmic scaling (can be used together with scales
, which can be helpfully used to negate values prior to log transformation)If a single string is specified it will apply to all of the nonlinear inequality (equality) constraints. Otherwise a string must be specified for each nonlinear inequality (equality) constraint.
Usage Tips:
See the scaling information under specific methods, e.g., method*scaling for details on how to use this keyword.
