preconditioner or preconditioning for Constrained Nonlinear Optimization VI and Downhill Simplex nD VI

Dear users,

 

do optimisation algorithms, such as the Constrained Nonlinear Optimization VI and the Downhill Simplex nD VI, use internal preconditioning or does the user have to do it on their own? There is no note or word in the help about (pre)scaling the functions or the variables. On the other hand, there is no word about any nonnecessity to do so.

 

Cheers,

Hello ghighuphu,

 

the VI's "just" do their algorithm, so they aren't using internal preconditioning. The user have to do this by himself.

 

Best regards
