Define the characteristic values to scale linear equalities
This keyword is related to the topics:
Alias: none
Argument(s): REALLIST
Default: vector values = 1 . (no scaling)
Each entry in linear_equality_scales
may be a userspecified, nonzero characteristic value to be used in scaling each constraint.
See the scaling keyword in the method section for details on how to use this keyword.
Scaling for linear constraints is applied after any continuous variable scaling.
For example, for variable scaling on continuous design variables x:
we have the following system for linear inequality constraints
and userspecified or automatically computed scaling multipliers are appplied to this final transformed system, which accounts for continuous design variable scaling. When automatic scaling is in use for linear constraints they are linearly scaled by a computed characteristic value, but not affinely to [0,1].
