Hello.
I have two problems with RooFit and MINUIT2, and despite extensive searching, I haven’t been able to find solutions. I would greatly appreciate any help or guidance on these issues.
-
The RooFitResult class in RooFit has a
status()
method that returns a MINUIT status code according to the ROOT Reference Guide. I would like to understand the meaning and interpretation of this status code. Could someone provide more information about that? -
I have encountered several flags in the output from MINUIT, as shown in the example image below:
I have been unable to find detailed descriptions or explanations for these flags. I would greatly appreciate it if someone could provide me with the meanings or interpretations of these flags.
Thank you in advance.
ROOT Version: 6.26
Platform: ubuntu 22.04
Compiler: gcc version 11.3.0
