Optimization VIs and parameter bounds

[jeanlucpicard]

Hi,

I have a question which I can't seem to solve: I want to use optimization VIs (Global Optimization or Unconstrained Optimization). I have some parameters which denote a distributions two endpoints, and therefore it is important, that one of them is higher than the other. Is there a way to fix this relation, that let's say parameter no. 1 is always less or equal to parameter no. 2?

I tried applying a min&max function to select the lower and higher one of the two parameters, however I think that it would converge better if I could force their relation.

Thanks

I forgot to add that I use a two-step optimization by using the constrained global at first to give a reasonable initial guess for the unconstrained one, this might be important
