Specify weights for each objective function
Alias: multi_objective_weights
Argument(s): REALLIST
Default: equal weights
For multiobjective optimization problems (where the number of objective functions is greater than 1), then a weights
specification provides a simple weightedsum approach to combining multiple objectives into a single objective:
Default Behavior If weights are not specified, then each response is given equal weighting:
where, in both of these cases, a "minimization" sense will retain a positive weighting for a minimizer and a "maximization" sense will apply a negative weighting.
If scaling is specified, it is applied before multiobjective weighted sums are formed.
