Hi Zemax Team,
I was pleased to see the new optimization routines in 21.1, but I have not yet succeeded in getting a better result (either in MF value or speed) with them than with the DLS optimizer.
For example, in a typical imaging system design, optimizing for best RMS spot, I have a design with a starting MF of 0.02 with 12 variables, all thicknesses and radii. The results I get are:
DLS: 0.0011 in 1.7 secs
DLSx 0.0035 in 3.6 secs
PSD 0.0035 in 3.6 secs
For reference, Orthogonal Descent (which I know is not intended for this kind of optimization) gave 0.0037 in 2.9 secs. Can you give us some color on what kind of optimization problems these new algorithms are intended for?
