Is it possible to extract the
Method which is used in functions like
FindMinimium, and partners when one doesn't set this option explicitly? Basic example:
NMinimize[x^4 - 3 x^2 - x, x]
What is used as
I expected to find some setting in
SystemOptions but was unable to. Obviously
AbsoluteOptions[expr] cannot be used in such a case since unlike a e.g. graphic, the minimization result does not contain this option information anymore.
Here is what is stated in the documentation of
With the default setting
Method -> Automatic, Mathematica will automatically try to pick the best method for a particular computation.
This tells us the chosen
Method depends on the input problem. Therefore, a fixed setting in
SystemOptions wouldn't make sense.
Additionally, there exists a document describing some internal implementations. Basically, you can extract most information from there, but I was hoping for a way to extract the used
Method during a run.
