Description

Hi. I am trying to minimize a sum of three terms for a parameter estimation problem where the magnitude of one of the terms is larger ( about an order of magnitude) than the other two. When I perform the optimization, it results in a much better fit on the parts of the system that affect the term with the larger magnitude. Could you please suggest how this can be avoided ?

Research direction

The issue names no file, test, or entry point. First clarify which Optimization.jl interface and objective-scaling behavior are involved, then establish a reproducible example for terms with different magnitudes. Done would require an agreed scope and a test or documentation change showing the intended behavior.
