scales
Characteristic values to scale each nonlinear constraint
Specification
Alias: nonlinear_inequality_scales
Arguments: REALLIST
Default: 1.0 (no scaling)
Description
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.
