Specify how each linear equality constraint is scaled
This keyword is related to the topics:
Alias: none
Argument(s): STRINGLIST
Default: vector values = "none"
linear_equality_scale_types
provide strings specifying the scaling type for each linear equality constraint, in methods that support scaling.
An entry may be selected for each constraint. The options are:
'none'
 no scaling 'value'
 characteristic value if this is chosen, then linear_equality_scales
must be specified 'auto'
 automatic scaling If a single string is specified it will apply to all constraints.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 equality 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].
