Characteristic values to scale each nonlinear constraint
Alias: nonlinear_equality_scales
Argument(s): REALLIST
Default: 1.0 (no scaling)
Each real value in scales
is a nonzero characteristic value to be used in scaling each nonlinear inequality (equality) constraint. They only have effect when the associated method specifies scaling
.
This keyword is required for scale_types
of 'value'
and optional for 'log'
. When specified in conjunction with log, scale values are applied prior to the logarithm, to permit log scaling of strictly negative response functions.
If a single scale value is specified it will apply to all of the nonlinear inequality (equality) constraints. Otherwise a value must be specified for each nonlinear inequality (equality) constraint.
Usage Tips:
When scales
are specified, but not scale_types
, the scaling type is assumed to be 'value' for this set of nonlinear inequality (equality) constraints.
Use scale values of 1.0 to selectively avoid scaling a subset of response functions.
See the scaling information under specific methods, e.g., method*scaling for details on how to use this keyword.
