Constrained Nonlinear Optimization

Hello,

I have some trouble using the  "Constrained Nonlinear Optimization.vi"

Apart from the manual I could not find much information on the algorithm on the internet... It look like often my program gets stuck in a loop inside the subvi "isisubopt.vi" (L-->inf , matrix inversion results in a matrix of zeros). This happens with some datasets, not with others, but when it gets stuck, there is no possibility to leave the loop and thus I have to quit the vi.

Is there reason for this eternal loop, and it there any way to avoid this situation?

Thanks, Dirk

Hi Dirk,

 

I'm not familiar with the algorithm, but the Wikipedia page is likely a good start point. There's a PDF at the bottom called "Introduction to Sequential Programming".

 

What is the difference in your data sets? Same size?
